What if you loose your LIFE too XPS? can you afford to replace it? I think you guys are to focused on the unimportant stuff like planes and money.Safety is first on the list for me then all of the stuff that can be replaced after that.

Maybe we should all give up and just fly foamies!

I can afford to loose a few of my 40%ers, but I will be damed if I will be loosing one to XPS!

A foamy can kill you too, buttface. That would be really ironic. . you use XPS exclusively for foamies, because it's not safe for gassers, then it locks at full throttle and kills someone by hitting them in the head. . .

weirder things haver happened. Hopefully we will never have to visit this scenario.

... I went in expecting it might not work, like I do with every peice of electronic I put in my planes. Am I dissapointed that for now it appears that things were not as I percieved them to be? Yes. Am I sorry I spent my money and possibly lost a plane to it (since I cannot 100% determine that).....actually no, I'm not sorry I tried it. It does suck the time and money I was out but I never put anything in the air I cannot afford to lose.

...
Now this really confused me... If you 'went in expecting it might not work' then, are you disappointed that it works for you or are you disappointed that it was not as advertized? Of course you should not feel sorry since your expectation of the product was low in the beginning.

What happened to Quality Control and Reliability? Every piece of work we do in our shop goes thru rigorous unit testing, quality acceptance before it goes production and released to the users. So this XPS company exempted themselves and used the user community to do their unit testing and quality acceptance for them, without warning? And I was about ready to buy it proudly seeing it's made in the USA. I was following his development thread in RCG since 2005... sheeessss...

The same could be said for ANY R/C flight system. Go C/L. Of course, now you are at the mercy of a thin control line, and the aircraft is at ground level a large portion of the time. We all should do good to remember at all times that there is ALWAYS a danger of loss of control when we fly, regardless of which specific control system we use. It IS the nature of the beast, whether it is 27/49mhz, 72mhz, 50mhz, 35mhz, 900mhz, 2.4ghz, of whichever manufacturer origin. On 72mhz, an aircraft CAN get directly "shot down" simply by someone turning on the same channel.

If a signal gets blocked by another, the link WILL fail, no matter which brand you have. With that said, there are differences in the robustness of the link between the different link methods employed by 2.4ghz. No matter which you choose, you pays your money and you takes your chances. Put it in the air, and it WILL come down at some point. We all hope it is in control and upright at that time, no matter which control type we have.

While it is true that accidents can happen in RC (that's why AMA is there) no matter what electronic or equipment you are using, there is a difference between 'an accident that just happened' and 'an accident you already expected'.

If XPS know that their product is not as what it was advertised or that they haven't fully tested to verify that their product works as advertised and yet release it to the user community then that is not an accident... that is neglect. That is the same for the users... if after so many individuals had already shared some informations that the product is defective and yet continue to use it, IMO, you disregard the safety of other people around you. Never mind the $10K model you lost... but life cannot be replaced.

That's my opinion.

I don't use XPS. I went with a company with a long track record in this hobby, and I'm sorry to see the problems that XPS is having. But I have one question. Besides the fact that he may have lied about the system to his customers, which is another issue in it's self. How is XPS more dangerous then 72? Both work until they don't. Anybody that bought the system has every reason to be mad. You didn't get what you paid for. For this reason everyone has the right for a complete refund or a replacement with equipment that works the way it is supposed too. As I followed XPS I never saw how much Beta testing was done, or how many flights during the testing. For this reason I went else where for my system. Many of his customers went with his system based on price and wanted to believe his hype to justify spending their money. The lack of any answers from XPS tells me where this will all end. Remember AM, this is where XPS will be shortly. There are now two good systems on the market. For those that have XPS make the move and put this behind you much like the engine you tried and didn't like. In the drawer. Dennis

Dennis,

I'm a step ahead of you bro...got the Futaba FASST stuff on back order. The 8 channel stuff is still about three weeks out..no big deal.

As for beta testing...that's anybody's guess. How do you beta test and not realize you'll need a longer antenna? That's just one question of mine.

It's interesting, without the internet, he wouldn't have been able to get out his word of mouth advertising to start...and now, hopefully it will be his end as well as word spreads.

There are just too many smart people out there in this hobby that have the skills to do the testing themselves..which is a good thing.

I check in on this thread every few days or so and i haven't read anything about the test actually being done yet.

Did someone perform the test?

Side note: I never bought into the XPS thing , i think it was just a gut feeling. I feel sorry for the people who did buy into it.

If the test hasn't happened.........when is it?

Check post #505. Links to video of the tests are there.

Just a note on the test.

Xjet has not provided his data yet, only his results.

The other test is from a guy on RCgroups. He has video proof of his results. There are a few questions on his test raised about the intial power level and what it relates to in the real world as well as his test was performed without the antenna. But his results do show that XPS did not hop

I do not dispute his results, as it clearly shows that XPS has not hopped in that situation. I have asked for him to test FASST and Spektrum in the same test to prove that their features bypass this artifical interference he has injected. They of course should pass. He has also been asked to perform a few more tests....including lower power setting and with the antenna on.
One question I raised was what is the Minimum "large" increase in power needed for XPS to not hop (since XPS themselves admit it would not hop in that case). This recent test may fall in that category or may not.

XPS is still in Germany and have yet to comment on the thread on RCgroups (we all know they do not comment on FG anymore)

Things though, are not looking good for XPS at the moment.
