Exactly. I never said Xjet made money from his other interests. Only that he had them and loses credibility with just me. I was also confirming that I don't think you are a paid shill from either FASST or Spektrum/


As for JD's responses for hopping. I took the company advertising hype as just that ....Hype. I'm sure it actually hops from potential interference like it is advertising to do(under its special circumstances). Of course we have been shown so far from "PUBLISHED" tests that it doesn't hop in situations where both Spektrum and FASST work so the usefullness of it may be worthless.

So you can call it lying. I don't, I call it misleading advertising. Its done all the time. Its not an outright lie but more of a walk around the truth. Similar to the spherical antenna claims. Is it a true sphere? So far no. But it is spherical in nature and I've seen Government contractors use the same term for the same type signal. It all comes down to semantics and telling the customer what they want to hear.


And yes I was a one time user in GS planes. Yes I lost my plane to what I feel was an XPS lockout but I couldn't recreate or prove it. Was it due to interference? I don't think so. I lean more toward the shadowing effect from the plane blocking the signal. And no they didn't Buy me a brand new plane like so many think. They also didn't pay for the repairs to the motor/electronics that were damaged.

Like I said before.......hopping makes no difference to me whatsoever. I didin't have hopping on 72mhz and its quite easy to shoot you down on that one. What I wanted was the telemetry and satellite RX's. When I bought XPS back at the AMA show I never thought it would take until now for the telemetry to show up and its not the version talked about at back then. Satellites also are still not available. With Spektrum I get after flight telemetry and satellites......as a plus I get 2 freqs to operate on as well.....I got tired of waiting on XPS and wanted to get off 72mhz so I wouldn't accidently shoot someone down at an IMAC contest or practice. Its as simple as that for me. I needed to switch to 2.4 for my own comfort. I can afford to lose my own planes for whatever reason. I cannot afford to be the idiot that causes you to lose yours and have to buy you a new plane. When you start flying GS you tend to fly with other GS planes more and more. 2.4 took that fear away for me. Spektrum became my answer as XPS has taken too long. I don't plan to switch back unless XPS comes out with all the gadgets and then some that would make the monetary loss I'd take worth it to switch again. So far I've invested just a little in XPS and every plane from .40 glo to 42% has switched to Spektrum (I get to use my 10X still!). My foamies are on XPS but I'm slowly switching those over as well. The less I have to mess with the module on the radio the better INMHO

So Fanboy, No I am not but I'm not 100% against the company either and don't feel the need to bash them online. I'm also not sponsored by any company out there so I buy what I want for my own reasons.

Kiwi, the scenario that JD describes for provoking a frequency hop is just about the *only* way it can be done and (barring software bugs or a bad implementation) I'm sure that exposing a system to that slowly rising noise-floor over a 15-second period may well provoke a hop.

But it's a useless hop -- because that's just not the way interference appears on the 2.4GHz band.

Interfering signals always appear more or less "instantly" because they are invariably a result of someone turning on some equipment that is transmitting the signal (which means a in instant "appearance" of the signal) or because you've flown from an area where an existing signal was invisible due to the shadowing effect of the surrounding environment, into an area where the noise source *is* visible.

So even if XPS does hop when exposed to JD's most artificial and unrealistic test scenario, it means absolutely *nothing* to anyone flying a model.

It's kind of like making seat-belts out of cotton-candy and saying they will protect you from injury - but only if you're traveling at less than 0.5mph when you hit something.

The original scenario that JD painted in his promotion of the system was that it would hop away from an interfering signal - which it clearly does not.

The other claim he made was that it pre-emptively listens to all frequencies on the band so it can hop away from potential interference. Again, this is absolutely untrue. The XPS receiver stays on its designated frequency and does *not* constantly scan the band between data packets. That's why it could not see the signal creeping up the band in Kiwi's tests.

The claims made by JD are not "just marketing hype" they are clearly lies that I can only imagine were made with the intention of presenting XPS as something it is not. The same is true of the mythical 8-element spherical antenna that simply does not exist. If you say something has a "unique, patent-pending eight element antenna" and can't offer any proof - or even the patent application number, then you are lying. What's more, if your supplier says "nope, doesn't exist" then you've got real credibility problems.

I can understand that some XPS users have effectively backed themselves into a corner by consistently supporting JD's claims in the face of zero evidence. For them to back down now and say "oops, we were wrong" would be too much embarrassment for some to bear (it takes a big man to admit when he's been duped). However, it seems that slowly (one by one -- or in the case of the RCG report, two by two), many of those former XPS advocates are finding out that the naysayers were right, to their very real cost.

When extraordinary claims are made for a product, all that any intelligent person reasonably expects is for the proof of those claims to be forthcoming when requested.

In the case of XPS, (despite the manufacturer's promises) the proof simply hasn't been forthcoming at all. And, given the ever-increasing groundswell of evidence that supports the claims of those who question JD's hype, only someone very naive would continue to believe those unsubstantiated claims under these circumstances.

Now you've really got me scratching my head.

The very fact that I work professionally in an area which qualifies me to make authoritative comments on the technology being discussed somehow lessens my credibility?

Is it only those who have no technical knowledge whose word carries any weight in your eyes?

I don't get it (I hope someone else does).

No, hype is where you "overstate" a fact.

Saying the latest Ford has "the best paintjob in the business" or that your new 33% YAK "flies better than any competing model" is hype.

Saying your Ford has "the best paintjob in the business" when it isn't even painted, or claiming that your new 33% Yak "flies better than any competing model" when it doesn't fly at all is just a lie.

JD said XPS hops away from interfering signals -- it doesn't. That's a lie! There are no shades of grey there.

And remember that JD as consistently refused to submit XPS to an independent testing authority so that his claims could be proven once and for all. You'd have to ask why that was don't you?

Sorry SP, you're just making excuses here.

This is kind of like saying to someone who bought that new unpainted Ford and complains that "it's got no paint" -- "yes it has, you just can't see it". Whose job is it to prove that the bare-looking and slightly rusty metal is actually painted?

What about the "unique eight-element patent-pending design" that JD was raving about and which DigiChip denies exists? That is a clear lie. If you claim to have something that you clearly don't, that's not hype or marketing - that's a boldfaced lie.

SP, if you sold me something and we agreed on a price of $1,000 then found that I only sent you $50 (after you'd delivered the product), would you consider my promise to send you $1K was a lie or I was just engaging in a little "hype"? When people loose thousands of dollars worth of models because JD has engaged in "a walk around the truth" -- isn't that the same as me sending you only $50 after promising to send you $1K?

	Quote:

Yeah but it makes a *hell* of a lot of difference to someone who's flying an expensive model at the time an interfering signal suddenly appears on their operating frequency with XPS.

	Quote:

True, but at least on 72MHz you're not competing with a raft of other RF equipment, some of which is being undoubtedly operated outside the FCC regulations.

But hang on.. JD said that XPS doesn't need satellites - he's lying again! And then he said that satellites would be available at the same time as telemetry -- but they're not. And he said that satellites wouldn't be used for diversity purposes, only as part of the telemetry system so there's no gain for large-model use there.

Well I'm glad you can sleep well at night by stepping up to the plate when JD and XPS is criticized. It must be nice to know that someone might just end up buying XPS after reading your pseudo-endorsement of the company/product and lose a lot of money as a result.

Let's face it SP - JD is a huckster, he has a long record of deceit, dishonest statements and failures to fulfill promises in respect to the functionality of his products. He didn't earn three degrees while still at high-school (but he lied about it and said he did), he left a lot of people swearing and cursing at him in the Amiga and Paintball markets and now he's repeating this MO in the RC market.

That anyone would stand up for this guy beggars belief.

Please think about the next person who loses a model or might even cause injury due to JD's blatant lies in respect to this system.

You don't have to say anything bad about it but please don't stick-up for JD and XPS, it's really a bad look.

[sweetpea]

Hmmmmm

Stick up for XPS? I have not done that....I've stated facts only. What I have done is not go online and belittle a company for any reason. I don't care what JD did in his past life/job/marriage etc etc. XPS is not just JD. Ok I know JD is the one online all the time. My dealings with XPS were with Scott not JD and that is what sold me on the product in the beginning. I knew about JD's torrid past when I bought the product. Was I duped? Sure, I guess you can say that. Not the first time nor the last time it'll happen where I bought something that didn't live upto expectations. That happens all the time with all types of products.

As for the system being dangerous and I need to warn every living person not to get it? That is very far fetched and not my place. Plenty of people are happy in foamies/GS/jets flying it, and plenty of people are unhappy and plenty have crashed.

I won't join your band of merry XPS bashers. Just like I won't join the band of Futaba FASST bashers for not getting it right the first time (Zguid) and overheating issues nor will I joing the band of Spektrum bashers for the brown out and Version 6.whatever they are on.

If someone wants to buy XPS......power to em. I'm not that high on my self to think that explaining my own experience and reasons why I'm not currently flying it are enough for a person to go onine and buy it. I'm pretty much nobody to anybody. I prefer it that way.

I let the user read my actual real life experience and my real life decisions based on my experience. What they chose to do with it is their business. I've got no agenda to stop folks from using XPS nor push them to some other brand.

Some of the biggest things you seem to forget Xjet when talking with me. I'm not everyone else, I'm just me. I don't care about hopping I don't care what everyone else wants in a radio, in a module, in a RX.....I care what I want and that is it. I thought I made that abundantly clear. If I did care about hopping I would have waited for FASST modules for my JR radio. And I'm glad you actually read my post (but only partially quoted it) and see that I'm very unhappy that satillites are not out yet. I didn't buy into the "doesn't need them", but I also didn't think it would take 2+ years for them to show up (if they ever do).

And I'm sure JD is a huckster.......just like Billy May (who is now selling health insurance also) doesn't really effect me in the least bit. I buy what I want. Alot of things in life I've tried because they appeared to the solution to things I've had. Some have and some have not. XPS for me was a solution but its timetable of complete features has outlasted my patience. Simple as that.

Many others are like me and don't care what JD has said in the past or present, it doesn't effect my buying decisions. Others are like you and won't buy from someone that isn't 100% factual.

Some will be Pissed that they felt the adverstising was a lie and others will feel like me that it was over stated/hyped whatever you want to call it.

But in my case.......XPS antenna/hopping were not the reasons I first bought it. I could care less about any of that. So it comes out its not as expected.....no skin off my back. What rakes my skin is the lack of the system updates (telemetry and satellites) which is why I bought it in the first place.


And the you being an expert in the field? Who says I'm not one in the field also? Who are you to me other than a fellow R/Cer just like I'm only that to you. I don't feel the need to come online and tote my knowledge on everything like I'm the expert. The fact that you are doing R/C reviews online, writing manuals for other 2.4 devices, are in the 2.4 field and have stated that you want to come out with your own version of a 2.4 unit (no profit mind you)

All of that makes you lose credibility with me when you don't do the exact same belittling of Spektrum and FASST of their problems as well. And I'm not talking about the owners but the faults of the systems themselves. You don't go on those forums and tote your 2.4 knowledge about why it happened and how you could fix it.......What gives?

[Woketman]

I don't think Sweetpea gets it amd I don't think he is capable of getting it. Apparently he does not mind the manufacturer lieing to him at all. I do.

You say that now but just a couple of posts ago you stated: "I'm sure it actually hops from potential interference like it is advertising to do(under its special circumstances)"

How can you be sure? You state this as fact but there is absolutely *no* evidence to support that claim, not even from JD. XPS's hopping is *not* a fact -- it's a claim that has failed to be substantiated by any credible evidence.

It seems that it's not just your idea of what constitutes "lies" is not the only thing at odds with the norm, you have a funny definition of "facts" too.

And the implication is that others have? I think the reasons for questioning the company and its products are very valid. Ultimately it could be human life and the public's perception of the hobby that is at risk here. Just look at the "near misses" (especially in Europe) that have been attributed to XPS. I don't think it at all unreasonable that some people feel it important to speak out and challenge the unfounded claims of a company and it's principle when such high stakes are involved.

	Quote:

That's fine, I've seen nothing from Scott (apart from his implicit endorsement of JD's BS) that would lead me to believe he's not a straight-up guy and I've never criticized him.

Please read what I said, not what you *think* I said (let me quote from my previous post: " You don't have to say anything bad about it but please don't stick-up for JD and XPS, it's really a bad look". Shall I type it more slowly?

And although you clearly wish to accuse me of "bashing", I think you'll find plenty of posts from me where I quite clearly state that XPS is a fine system for sports-type models where a second tier system provides perfectly adequate control and safety -- which, by your own limited use of the system and preference for Spektrum in your more valuable/dangerous models, you now clearly agree with.

	Quote:
	I won't join your band of merry XPS bashers.

Once again... you really don't seem to be reading what's being written here. Either that just as it is with the definitions of "lies" and "facts", you attribute a completely different meaning to the term "bash" to the rest of us.

Raising valid concerns about a product and its manufacturer is *not* bashing -- except perhaps in your world where lies are "a walk around the truth" and facts are only what *you* believe to be true. Sorry SP, but you would appear to have the same "different world" problems that JD has.

Well I do have an agenda and I'm not afraid to admit it. My agenda is to ensure that people make informed decisions based on the real (not SP's interpretation of) facts. I'm sorry if that is something you can't handle but you really ought to stop and ask yourself why you'd want to stop someone from pursuing such an agenda.

Yes, but when you come out and claim that JD's lies are not lies and that your beliefs are fact - you are distorting reality and disguising the truth. In effect, that's an implicit support of JD's deceit - with the obvious implications if someone acts on your assertions.

	Quote:
	And I'm sure JD is a huckster

Well we agree on something :-)

So why lend him *any* endorsement at all? Isn't that a little unfair on someone who might be teetering on the verge of buying an XPS system (based on JD's BS) and, based on your implicit endorsement, goes ahead and does so -- possibly with dire results for himself or others?

Except I'm the one who started this thread titled "Independent tests prove lack of frequency hopping with XPS". I then withstood the barrage of insults, denials and cries for "proof" from the pro-XPS brigade". Strangely enought, some 110 pages later, I'm still right and the pro-XPS guys are still wrong. Work out for yourself who's the expert based on the evidence before you.

	Quote:
	I don't feel the need to come online and tote my knowledge on everything like I'm the expert.

So let's get this right... firstly, because I work with this technology every day, my input is of less worth (to you) than if I swept drains for a living. And now, because I am a relative "expert" in the field, I should have shut up and not said a thing about an issue that I (and most others) believe is very important. Wow SP, your world is really weird!

Once again you speak from a position of ignorance.

Why don't I do "exactly the same belittling of Spektrum and FASST of their problems as well"?

Do the research SP, clearly you haven't or you'd have read this article I wrote quite some time ago (FASST goes FuBar) and many of the other posts I have made in respect to FASST and Spektrum deficiencies.

And are you also saying that *nobody* who:

a) works in the RF/digital coms/telemetry industry
b) has an objective review/news website related to the model industry
c) creates a not-for-profit open-source RC system

has any credibility in this area?

Sorry mate, you've really lost me know.

And by the way, you never did answer my question regarding your position if I said I'd pay you $1K and only paid you $50. A lie or "a walk around the truth"? Which would that be? Don't dodge the hard questions.

[sweetpea]

I fly what I want....manufacturers and so called online experts don't make my mind up for me. I do use both for education but the final decision is upto me. I no more believe JD's hype than I believe your all knowing in the 2.4 regime because you work in the field.

You can also think what you want about what I don't know about RF......it really matters nothing to me or I'd post my resume.

You are correct you started this thread with accusations and never backed it up (similar to JD but I do give you more credit than him you'll be glad to know). Kiwi backed it up for you and I have given him great credit on his test. It proved what you only spoke about. So you were right, but someone else had to prove it for you. But you were right, I'll give you that all day long

As for those that say I don't get it? What I don't get is why so many people blindly believe every piece of advertising they see. I didn't buy into all the patent pending, spherical, freq hopping, 2 way communication , we get it right the first time, interference immune etc etc etc B.S. What I did see was for the potential of real-time telemetry and satellite RX's to enhance the ablility of a pencil beam signal to be seen. No other manufacturer was offering that at the time. Spektrum hadn't even announced modules yet and I was not about to downgrade to a 7ch parkflyer type radio just to go 2.4

Without these enhancements XPS was too much a gamble of mine to try a second time in my large investments. Plain and simple. It was reasonably priced and I gave it a shot. I waited a reasonable amount of time for the enhancements and items didn't come out. I moved on to other another system that in itself has its own shortfalls but offers these enhancements.


So yes I live in my own little world and I'm ok with that. I don't believe everything I read from online experts or companies advertising. I try items that sometimes don't work out for the best and I don't go out telling this guy and that guy not to use something or you have to use this thing. I do tell people my own experiences so they can make up their own mind if my experience is usefull to them or maybe it has no bearing on their decision at all.

But I am not in the business to tell people what to buy or not buy. I live in the Ole' USA where people don't have to be told what to buy and use, we have freedom of choice and Yes sometimes the choices are bad or the person didn't do their own research but at least we have that choice to make and I wouldn't give that up for anything.



To sum it up

1) I don't care if JD lied or overstated facts or mislead advertising, I hardly pay any attention to that in my purchase decisions or I'd own alot more useless items than I do now or I would never buy anything. There is so much false advertising and lying in advertising that you can't get away from it. Just take fuel mileage for example (since everyone brings up car and seatbelt bits). Fuel mileage is based off a car on a roller in a warehouse with no wind resistance. That is very inaccurate to what you will see "real world". Also doesn't anyone find it very funny that in less than one year every car manufacturer now has every model over 30mpg since the energy crisis? Makes you wonder how they did that so quickly.

2) I did buy XPS for its future enhancements which after tooooo long a wait for me have yet to come about so I moved on.

3) I do believe that XPS hops (it does it at start up and that is proven) but has no useful hopping technique that has been proven by users or manufacturer once you are bound. There is hearsay on both sides that it does hop and that it doesn't at all but neither can confirm with 100% or prove it either way. Kiwi's came the closest, but that was just a few scenarios. Will it hop if it meets JD's strict guidelines? Of course the answer is it doesn't matter because its of no use to use in the R/C. But I won't put the blanket statement that it doesn't hop out there.....I know you've used the statement it doesn't hop to any realworld use in R/C and I think you are better of using that......it is more credible and makes more sense.

4) I also think nothing will come of any of the complaints that were filed......Legalize is a very tricky thing and its quite easy to get out of it on how you interpret the wording of the advertising. People get paid alot of money to find those loopholes (more money than those who are paid to close them). But it was a step in the right direction.



And your money analogy is not quite correct. For me I paid say $200 (I can't remember exactly what I paid) for XPS to have the telemetry and satellites as future options. They never came about. I took that $200 as a loss....but not the entire $200 as I still have the module and RX that work in smaller planes just fine.....so I'm out maybe $50 bucks, at most $100. There are those of us out there that lost planes while using XPS (I won't say everyone lost one due to it but will say it happened while on it...that covers everyone using it who crashed for unknown reasons or known reasons). We are possibly out more money. Though I knew the risk of pointing a pencil beam at my plane with a 1inch RX antenna. The odds were not in my favor but I attempted the risk anyway.

Not everyone understands RF and I do feel for their lack of knowledge of how 2.4 works vs 72mhz. They risked more in my opionon because they went in blindly. And I don't blame JD/Spektrum/FASST/Airtronics......most of these folks didn't understand how 72mhz worked either, they just knew how to set it up from those that paid the price decades before them when control line went to R/C and folks built their own radios.

I guess you can say we are seeing the same thing over again with 2.4 (not just XPS). 5yrs from now when 72mhz is a distant memory and everyone treats 2.4 like 72mhz was treated will the new flyer at the field know how 2.4 operates and why? Most likely he will just put it in the plane the way the directions show him or his instructor tells him to and he'll go fly. No wiser of how the RF works and doesn't work.

I really don't want to argue with you online, it serves no point.

You don't like the XPS system for your reasons (mainly JD)

I prefer not to use it for a different set of reasons (telemetry/satellites)

You use your posts in any XPS forum to prove your point that JD is a huckster and stear clear of XPS unless you fly tiny planes.


I use my posts in XPS forums to give my experiences with the system (good and bad) and the reasons why after those experiences I chose to use it differently or not at all. I let the buyer make up their own mind whether or not they want to purchase.

We actually are doing similar things......from different angles, different prespectives and different methods.

You know, this one little paragraph pretty well sums up the entire reason you started this thread. Personal attacks, name calling, discrediting reputation, hell he just revealed that his Fiance' is battling a terminal disease. Want to take a shot at that one too? It's just as relevent.

You say that you aren't bashing, but merely raising concerns about one's product. What you have written above has nothing to do with raising concerns. It is all about trying to make one person's life absolutely miserable... and nothing more. And look what you have done along the way. On this wild crusade (agenda) about how right you are and how wrong everyone else who doesn't agree with you.

Bruce, you ripped apart SP, who has been one of the most neutral posters. The guy doesn't even use XPS gear anymore, and you jump him for not joining your little cause. All just because he choses to not speak badly of a person, or his company. He sounds kinda like me... if you find something that doesn't work, you find something else, and you move on. I don't feel the need to broadcast my bad experience to anybody and everyone who will listen, because you know what? After a while there will be something else, and then something else. Pretty soon nobody believes you or wants to hear what you have to say because it is always whining, negative, and demeaning.

I see your point about lying about degrees though. Don't you just hate it when someone says that they are something that they are not?

It's time to let it go. You have said what you have said. No need for more head games or word twisting... as long as in your mind you believe you are right, then mission accomplished. You don't need to convince the rest of us.

OMG!!!!

I don't think Sweetpea gets it amd I don't think he is capable of getting it. Apparently he does not mind the manufacturer lieing to him at all. I do.
Maybe you have been affected by the "XPS Reality Distortion Field". There is a history of these things happening in the past on other sites plus the Paintball world.

Just another Fanboy!!!

Scubacb? I wonder. Could he and all the rest really be JD under different member names? I am beginning to have my suspicions.

Yep, factual, to the point and non-biased. Typical responses against anyone that will not jump on the same band wagon.

Tomoul: "I hate to say it, but that doesn't cut the cheese either. XPS has to survive an interfering 2.4 GHz transmitter being switched on instantly. It has to survive and hop to a free channel. That's the basic test premise. Not some "slowly rising noise floor" or esoteric stuff like that. You fly, and someone switches on their FPV system on the same channel, or an ATV station goes on air across the valley."

Still don't get it do you. Count the number of planes up at SEFF. XPS was a part of it. (FACT) XPS planes flew just as well as FASST or Spectrum planes (FACT). Pretty much proves it works with other 2.4ghz systems. Duh, all these 2.4ghz systems are built to be non-interfering. That is part of why you don't need a flag.

XJet, talk about draging a dead horse. You still have a problem understanding coverage versus antenna patterns. Since I worked in communications jamming and testing of it for a number of years I do understand the difference. Yes, it is possible to have spherical coverage without having an isotropic antenna. Look at an antenna pattern at the -12 or -15 db levels or lower. Now compare them to the db requirement of the rx. At some point the RX functions no matter what the orientation. Thus you get spherical coverage. BTW I missed where you posted about where you got your EE bachelors degree or your masters degree.

Kiwi's post was the only thing even slightly new here. Good luck. Try to get some info from Futaba and Spectrum about how they work too. I understand that Spectrum does not necessarily work if one of the channels is lost. Is that true?

BTW got my telemetry system today. Enough of this time to go build and fly aircraft not wade through this.

BS... the medical status of JD's fiance' has *zero*bearing on anything that's being discussed here.

	You say that you aren't bashing, but merely raising concerns about one's product. What you have written above has nothing to do with raising concerns. It is all about trying to make one person's life absolutely miserable... and nothing more. And look what you have done along the way. On this wild crusade (agenda) about how right you are and how wrong everyone else who doesn't agree with you.

Why is it so unreasonable to expect extraordinary claims to be supported by evidence?

And you seem to forget that on several occasions I've made open and honest offers to help JD sort out the technology and the PR mess he's created. If I were trying to make his life absolutely miserable, why would I do that?

Have you ever stopped to think how miserable those people who have trusted the claims made for XPS, only to have thousands of dollars worth of models destroyed as a result?

	Bruce, you ripped apart SP, who has been one of the most neutral posters.

"ripped him apart"???

He questioned my bonafides and my motives - I responded. He also made claims about me that were patently false and I presented the evidence to refute those claims.

If simply correcting people's false allegations is "ripping them apart" then yes, I'm guilty. What do you have against the truth?

Then why do you even bother chiming in here? I think most who have seek Kiwis tests and who have learned from this thread realize full well the true state of affairs with XPS and JD and I doubt you're going to change anyone's mind by repeating JD's lies. The FG audience is a little too intelligent for that.

Remember -- I'm more than happy for people like yourself to fly XPS as much as you like for as long as you like. What I do find objectionable however, is when people like yourself try to dismiss the very real deficiencies that have been proven here and elsewhere. You can not deny the results of the tests shown here and you should not be telling other people (who may be contemplating purchasing a 2.4GHz system) lies about its capabilities. I certainly will step in when I see that happening because I don't think it's fair on those people that they are not given the right to make a properly informed decision.

And by the way -- please re-read this post. For one so hot on proof, you still owe us a whole bunch of it.

Sounds like a possible description of only one side of the discussion. Here is a pro-active suggestion. Spend more time flying, and less time arguing about systems you don't use or intend to use. Stating that I use XPS should not require you to fit me into one of YOUR definitions. AND, the most logical place to use any "manic sort of way" description of actions here in this discussion is misplaced with those who actually use XPS with no difficulties. I also quite disagree with the patently unprovable false allegations of some that ANYONE who doesn't speak badly about XPS is either: 1) a "fanboy" or 2) a "paid shill" or 3) JD himself in a multiple-user account format The first is simply derogatory. The next two are simply laughable.

Amazing that you could assertain all of that from my post, you are obviously a bit of a mind reader, but unfortunatly you where reading your own mind.
