Independent tests prove lack of frequency hopping with XPS

Is there an echo in here?

Don't be too harsh, he's obviously an XPS enthusiast just trying to spread the word.

He's only made two previous posts and here's one of them.

Crash-warranty for modules? Should give some very creative explanations of "what happened".

XJet, I enjoy reading your stuff. When these things first came out, all I remember hearing was "you absolutely don't need more antennas, but we'll put 'em there if it makes you feel better". Interesting saga.

LOL I was just checking this out, pretty sure that's the same software Kiwi was using..

Same here,i was one off their first victims!!

Indeed, WiFiSpy2. You can get it at thinkgeek, among other places.

But hey, in all fairness this DOES look genuine. Well, it adresses one of the two major concerns. Now they still need antenna diversity and stop claiming that their "magical rod" possess HF-properties that it does not.
The remaining question is whether the continuous frequency hopping keeps working under interference conditions.


A quick note as to the situation in europe: One of the largest shops over here, "Schweighofer", has recently sent out it's "latest news" catalogue for this winter. Every single RC system is in there: Futaba, JR/Spektrum, Assan, heck even ACT. But... no IFS. Graupner transmitters are shown with 35MHz modules and 2.4GHz modules by Futaba and JR. IFS is not mentioned at all.

I've been reading what JD has written and watched carefully his responses over at RCG.

It would appear that Graupner may have had a little talk with him and asked him to stick to *their* script by toning down the rhetoric, keeping the claims within the realms of reality and stick to facts not hype.

If this is the case then it's a *good* thing.

Also, if the XbeePro firmware is to be reflashed (as part of the V3 upgrade) to support it then FHSS may well be on the cards for XPS, which is another good thing.

The new JD seems to be a far more responsible, believable, honest guy than the old one and I'm hoping that the revised system (with satellites) will be a whole lot better than the original too.

I await the release of V3.0 with an open mind.

XJet, I don't see the economy of using an entire 802.15.4 module just to access the H/W layer. The JR and Futaba RF chips are maybe $1 in quantities of 1 (reel). Still, the ZigBee modulation and coding is probably more robust than our current systems. Also, 16 channels meets the ETSI FHSS def. for Graupner sales in the EU. Depending on the programming, this could be an excellent system or another botch job. However, it takes a lot of cable to daisy-chain two satellites - one in each wing.

xjet you crack me up. as you know i know jim from my past life. it just goes to show people that right it right. i commend you for standing up to the truth and making others prove what they speak. honestly a lot of people out there owe you a big thanks for saving them a bunch of money on wrecked gear. also this shows us your softer side as to somewhat forgive and let the true side of you out.....lol

Any word on the V3 upgrade yet?

If you're talking about testing i won't have a chance until after Christmas -- I'm busy tooling up for a UAV contract that starts next month and having fun like this:
