Independent tests prove lack of frequency hopping with XPS

I'm surprised to see that 'Ze Germans were fooled by JD. . .

[Julez]

Well, Graupner was.
Word is out in all german groups that XPS does not work as advertised, and most people are switching to Fasst.
However, Graupner employees have allegedly stated that more than half of all sold iFS systems go to ship drivers and construction vehicle modellers. Honestly, these guys will never notice if the system does not hop. It is difficult to crash a caterpillar

This is weird.........

I have tried to keep updated on this thread to see what's all going on in the XPS world. I have made a choice to get the newer futaba TM-8 MOD and Reciever for my 9Z.

the weird part is , that the last 30 pages or so of this thread has XPS being defended by numerous guys who are almost "ALL" new members , which have pretty much only posted in THIS THREAD.

maybe a little JD and friends spamming going on?? just a thought.

Yes, there was a call in the XPS support forum over at RCG for the "fanboys" to come over to FG and post positive comments about their experiences with the system so as to dilute the bad press the system has been getting here.

hehe....that's what i figured. Every time someone completely defends or slams a product , and they are a totally new member , you always have to read between the lines and figure out what their objective is. In this case , it seemed pretty obvious i think.

Yep. Obviously there are plenty of folks who have good luck with the product, and do not sit around all day telling everyone over and over and over...... Maybe, just maybe, they are just passing on their experience and then moving on. Sounds like a good idea, eh?

[JEFFRO503]

NO....it actually doesn't. Why is it that a ton of guys here at FG have had the problems with XPS , and a bunch of guys from RCG ( that all seem to be buddy-buddy with JD ) seem to have no problems. I like RCG , so don't get me wrong , but to be honest , most of those guys over there fly with something like $300.00 .40 size airplane. Losing something like that isn't like putting in a $8000.00 , 40% aircraft strait into the ground.

Besides the fact......i haven't seen one video , or anything proving that the stupid system hops. All i have heard was a bunch of RCG peeps over here saying it does.....but yet can't prove it.

Your right......the argument is over. "It doesn't hop"

so along with the original post in this thread......looks like the guys we're right all along.

I'd use XPS in one of my foamies i guess , but only if it was given to me. It wouldn't be worth anything more than that.

I DO honestly hope that Jims new 900mhz system is a great one. I believe he put a lot of time and effort into the system he has now , but it just doesn't perform the way he said it did.

Seems like a lot of innocent people got taken advantage of , and even lost some very expensive aircraft because they believed in Jim. I simply think he let them all down.

Sure , there are a lot of guys who have had a great experince with the XPS system. BUT , there are quite a few that haven't.


I'd say ( just a guestimation ).....maybe it was like 60% are ok with it ( just ok) and the other 40% had problems with it. ok , ok.......even if it was 90% being happy.......having 10% of the people having problems with it???? DUDE 10% of the people being unhappy with a system that is supposed to protect your aircraft.......that's pathetic!

[KrisW]

Actually I am 100% unhappy with XPS . .which is why I never bought it

As for the 900 mhz system, according to some posts about it, the Xbeemodule it uses is a bit of a power hog, but no one is sure it can HOP, protect the plane from a "rising noise floor" or do anything better than the 2.4g system. And, believe it or not, 900 mhz IS a pretty active frequency band. . .

... with small bandwidth and low datarate.

Would be hard to fit RC into it.

In Europe it would be even harder, because regulation is much harder then on 2,4GHz.

[Wojcigitty]

Even if his 900mhz system was excellent, I probably wouldn't buy it because:

a) How would I know which claims he made about the system were true/false?

b) After watching his fabrications about XPS fall apart, does he really deserve my custom? I realize that it's a tough market out there, and you've got to do a lot to get ahead. Futaba and Spektrum both seem to have oversold their system a little bit (it's not as bulletproof as the advertisements lead you to believe), but nowhere near as much as JD.

Couldn't agree more !!!

About time someone stated the above

The problem with the XPS gear is that it does have some basic RF technical flaws which do not prevent it from basically working as such but they do limit its RF performance capabilities. When flying craft worth a few thousand dollars, you want to minimise any risks so XPS would not be the first (or second) choice for any of my helis...

AMEN to that...

There IS a point you are missing here. Of those who own XPS, how many of them do you think actually get online at Flying Giants to post their experience? I would put a reasonable percent at much less than 10%. Frankly, the dollar cost is just a number.

You paint the picture as if the RCG guys are not in the same class, and are all "buddy-buddy" with JD. I would state that the number of folks who actively participate in the XPS forum who even KNOW JD is less than the number on one hand. I for one, do not know him.

Hop? With something like this system, you will find it much easier to "prove" instances of not hopping than to find instances of hopping. Just because you cannot find that instance of "hop" does NOT make it a non=event. I sure would like to SEE different, but really, it COULD be that the parameters have not been met in the tests so far. If you feel that lack of "proof" matters to YOU, get some other system. For me, it flies my planes great. I am beginning to actively research other brands based upon service much more so than the "hop."

Bottom line? Go through and actually COUNT the numbers of posters who had good experiences, and actually COUNT the numbers of posters who had bad experiences. I have little doubt that the bad will either equal or outweigh the good posters. That does not mean that the system has a 50% or greater failure rate. It only means that those who desire to post have that rate. Which side of the fence do you think is more apt to post? Those with troubles with the system.

Post counts are meaningless.

If you like XPS, fly with it. If you don't, pick something else, and for goodness sakes, MOVE ON! If anyone stays this BH over an R/C system for as long as some of you have, you REALLY need to do a little self-analysis. It ain't healthy.

Cost only matters to the person with the plane. In fact, to plenty of folks flying those $300.00 planes, they look at that cost the same way YOU look at an $8000 plane.

[Wojcigitty]

Wrightme, you raise valid points. People are much more likely to post about something that does not work as advertised than something that does, or works better than advertised.

However, the issue here isn't the success rate of XPS. Lots of people are satisfied with it because they haven't had a problem. The issue is that JD has been less than honest in hyping his product.
