Independent tests prove lack of frequency hopping with XPS

[Kiwi]

Sweetpea,

Seeing as your a close friend of Mr Drews maybe you could ask him to post irefutable evidence on any web site he wishes to, as he obviously gave up coming here after spamming the site for six months for the free advertising, showing his XPS system hopping frequencies when noise levels rise in increments that he says cause the switch.

I´m sure its a whole lot easier for him to do that and show his customer base that the product he sells is what he says it is. I mean Spektrum and FASST are posting data scans showing where and how their system works.

Sure we (FG) are going do it but like Xjet it will take time as its spare time, its not our job, its not our business, but it is his so why on earth would he not put the critics to bed really fast by posting data that shows his system hopping frequencies in a noisy environment.

I know if it was my product I would be out protecting my products reutation in a flash. You would not be able to hold me back. So just maybe the guy to answer the question is Mr Drew, then we can confirm it with our external and independent testing here on FG.

Sounds fair to me I think!!!!!

I believe Mr. Drew confines his posting to http://www.rcgroups.com/xtreme-power-systems-483/

Well I can't do any testing till I see Xjet's method and data. To hold things constant I need that. Otherwise I have to start over....This wasn't my thread that I started. And I have tested my JR PCM, XPS and Spektrum module quite extensively.....just not with a 2.4 camera yet.

1) I'm not great friends with Jim. I am an acquaintance though. I've only met him once. And we really have not talked or emailed much since I met him. So I don't think he will listen to me anymore than any of you. Of course if XPS takes the time to explain every tiny thing on their system then they would fall even farther behind on 6ch rx's, endpins, XDP and telemetry with satellites (again satellites have been an option since the system first came out with telemetry, not just recently like many people claim. ). Then everyone would be mad at me for convincing them to do that instead of produce more products since it appears more people are successful than not. Or don't care that it doesn't hop in sudden noise levels

2) I can't speak for how XPS advertises.....I'm not part of any of that. And I've stated from the get-go.....I wish XPS would have chose FG to have their forum

3) Yes, I would think that any company would want to prove their system to the customer....but what is it to prove currently? They told all of us that it won't hop in one situation and they are trying to fix that because the customer doesn't want the feature (waiting for the high noise level to subside) since in this case it won't hop but tries to wait out the noise. Granted this was not explained to the consumer.

Next you want XPS to respond to independant tests that they themselves don't have access to the data on. How can they do anything....verify or de-verify when they are in the same position as us the customer and don't know the specifics of the test? All they did was confirm a setting in their programming...they didn't confirm Xjets test. (smart move on any companies part)

Xjet's thread was labled as if XPS never hops....but he only suggested it didn't in one instance that might not matter if it hops or not (again all the 2.4 systems might fail in this "test"). Until we have the data and exact techniques we will not know and we cannot recreate what he has already done and take it a step further.

Like I said......I'm glad he did his test.....just not happy he has decided to not show his results. I'm happy to wait until he has the personal time to show us. We all have real lives outside this hobby to deal with....I was never mad about his 2 week delay.

And I look forward to FG testing......and if I can help let me know.

This statement alone was the beginning of this thread. Then it went into a discussion of how XPS did not do enough to allay the concerns. Unfortunately, XJET chose to NOT provide the data from the "independent tests." He loses credibility as a result.

Had he started the thread with a "testing to follow..." the lack of data up front would not have been harped upon as much. While I use and like the XPS system, I would like to see the actual data from these "independent tests" to better evaluate the future of the system.

Hi Allan Have been using Airtronics systems for 25 years, with zero problems. Now they have a new 2.4 system that looks very good and different from the others. I don't have one yet, however if it lives up to the claims, its gonna be a winner. If you like, ill post again about it, when I get one. This new system looks very promising. Global Hobbies will be distributing Cheers

Absolutely post the info you get on it. The more info the better.

[buttface]

I absolutely LOVE XPS products! They are the best !!!!







But I think I will try out the Futaba FASST system now instead.

When I first started to look into 2.4 I read some of a threads on rcgroups. JD's responces left me with the feeling he is a snake oil salesman. I encourage anyone considering XPS to do the same, but look in the radio thread because he is known to reread and delete a lot of his and others comments in his own forums.

Sweety, you say you met Jim Drew only once, can you tell us about that, I heard you got a free plane from him because yours crashed due to XPS failure, I believe that's an automatic disqualification for you not to post in the 2.4 threads regardless of the subject. Are you now using the XPS system and in what planes, how many flights?

Must be nice... All I got was a kiss my ...

Why doesn't everyone chill out for a little while.
Kiwi said he will do testing.

It takes some time to get the equipment together.
And to be honest, he's going out of his way to help everyone out.
Its a risk to attach a website to this kind of testing.
I'm sure you all understand that.
But he's going to do it. And knowing him for a little while, he's 100% a honest straight shooter,
so the results he will get will be 100% the results he got.

So chill out, let him gather the needed materials and get to work.
I'm just as anxious as you guys... I have a 12Z that I would like to install 2.4 into,
but I'm going to wait to see what the tests reveals!

Kiwi, you da man!

[Plane_Reaction]

Xjet,

I feel your pain. Its like bashing your head against a brick wall. We all know XPS has not lived up to what we all thought it was going to be. I remember a huge thread, everybody jazzed up including me. Hell I even was able to click the buy button. Thank God I was able to cancel that order. I went with the DX7 even though it was only a seven channel. Ive always ran an emcotec unit or powerbox with 2 Lipo battery's so the voltage issue never touched me. Its been almost a year now, no hits whats so ever. I am now looking into getting a higher end radio and have been looking hard at the 9303. Xjet your tests are very much needed and appreciated ignore the fanboys. (I bet they love having that nickname. lol)

[buttface]

I like XPS!

[canavanbob]

Plane;
Ahh, another Spektrum "fanguy". Enjoy your Spektrum!
