Independent tests prove lack of frequency hopping with XPS

[Flyfast1]

I hope that my post did not offend anyone or cause any issues. Losing a plane is not fun and I feel for those guys that lost planes. I once lost a 1/4 scale ME109G and it took me five months to get over it. I was using XPS, but the crash was 100% pilot error. I don't fly jets, but I imagine that like my ME109G, it requires complete concentration. One slip up and that's it!

As an XPS user with a significant investment in the system, I was trying to provide information to other XPS users about upcoming upgrades. At least the company is engaged in trying to improve their product, which I think is good for everyone. Here's a link to one of the discussions, but there are several in the XPS form on RC Groups-->http://www.rcgroups.com/forums/showt...=840551&page=5

This thread and others indicates that XPS is adding additional conditions under which a channel change will occur, not adding the ability to change channels for the first time.

Buttface.........

XPS has proven just fine for smaller models. Not anymore reports of crashes there than with those NAME BRAND systems.

Of course it is up to the user to decide what they want and if the lower price is worth the risk.

Its not secret I lost a 35% while flying on XPS and I cannot prove it was XPS's faults that caused it. Regardless I am not flying XPS in my larger models until the telemetry, satellite and hopping issues are resolved to my satisfaction (not Xjet's, buttface, or anyone else's).


I'm still waiting to see Kiwi's results on Spektrum/FASST/ASSAN tests though.

I'm still waiting on this as well , it'll be interesting in seeing what these systems can do. IF they hop the way they are supposed to , then that means the equipment they are using to test this stuff is a legitimate source of testing.

I still for the life of me can't understnad what JD was talking about when he was saying it would hop ( XPS) if it detected noise a certain way ( like what you would get at a flying field ) , and that's why the testing equipment wouldn't work. A blast of 2.4 is a blast of 2.4 , and these guys tried it many different ways.

I wonder if any of the XPS guys get a little worried with other 2.4 systems around at the same field? I'm done bagging on XPS , i just hope everyone that IS USING doesn't lose their aircraft. Even the guys who defend the XPS system to no end.....i really , really hope that it doesn't come back to bite you in your ass.

Didnt Kiwi show the FASST system working in one of his tests with XPS ?

Yup.

[buttface]

I talked to JD and found out he is making a new case design.The new case will have 4 spring loaded legs on the bottom of the case that bend at the knees and ankles with tiny plastic feet that wear very small Nike Air shoes. I cant wait to see the proto type of this one! JD says his new design is sure to hop.

Hmmmm?? i think i may have missed that one. What about the JR/spektrum test....did that happen as well , or is that in the works?

BTW....which post has the Fasst test?

[Pale Rider]

It wasn't a FASST only test..he was actually testing XPS but had a FASST system running in the background and you can see on the video how it was hopping around the interference.

I can assure you that FASST is a true frequency hopper. It clearly shows in the fequency analyser, there is no doubt and it hops around all the time on its 36 channels - now here, soon there:

Spektrum and Assan never hop, but neither claim to do so.

Spektrum uses two independent channels, that is also clearly visible:

Assan uses only a single channel, EU version tested therefore the low signal power, US version should have same power level as all the other systens:

Not much different to XPSs single channel:

FYI: I read earlier today in a thread over on RCG that JD said he would release a video of XPS hopping after Toledo. True? Don't know but I guess we shall see.

[XJet]

Such a video will only have any credibility if he also releases details of the test conditions such that it can be duplicated by others.

Well, gee. . pardon my skepticism. .. isn't he developing new firmware that is going to MAKE it hop now?? Is this going to be a video of the NEW firmware finally doing it's job, or of the older stuff that no one can make work??

I was thinking the same thing

How is XPS doing at Toledo?
