Independent tests prove lack of frequency hopping with XPS

[Kiwi]

Gene,

Your correct in a sense but what if the XPS signal for example was more robust than say the others but the weakness is only in the inability to dodge a bullet.

If you look at the two systems available (despite the manufacturer) there are only very few possible differences.

Look at it this way. SPEKTRUM, ASSAN, WFLY, XPS use a non hopping 2.4 GHz system with GUID. The difference between SPEKTRUM and the others is really two radios and Rx's in one. None of these dodge a bullet.

The Airtronics, FASST, Corona and others yet to be announced use frequency hopping. So there are really only two systems available, just different derivatives.

For you Wildhare this is the system I have on order and yes I will get a new ASSAN system as well to be sure I'm up to date. Same with the XPS, it will be a new version so please guys there is no hidden agenda here. In fact I might slow this thread down and start a NEW ONE with a name that is totally not brand specific.

Its going to take time and there will be many more people than me doing this. Getting the equipment and devices to test is going to take a while as living off the beaten track here means three to four weeks to get a product delivered some times.

In the mean time if you guys have anything you specifically want in the tests let me know here. I wont promise yes to them all but I will do my best.

Kiwi:

If I can assist you in acquisition of any of these items please email me tom@wildharerc.com. We ship stuff out of the US all the time so it's no great problem for me.

I looked at your profile, the phot shows you standing next to a full-scale Extra. Do you have any photos of the top and bottom of that plane? The fuse looks to be a nice scheme, I'm interested in maybe copying it for a new plane.

Tom,

Its the Chilean Airforce Aerobatic team Extra and they had 6 of them. I think they are dwn to five now after chewing up the tail of one with a prop. Sort of called for a hurried landing on the freeway.

Let me see if I can find some links to the site and thanks for the offer of some help. I will bein touch mate to share some ideas.

Here is a link to some of the stuff they do. This was in Great Britian this year but the show they put on is really some good stuff.

This really makes me believe in your qualifications (not), can you go over to JD's shop and help him out a little? FWIW I'll still listen to what Kiwi and X-Jet have to say on this subject.

Kiwi, it might be an idea to have the telemetry unit and telemetry updated XPS Rx's for the test, and also use logging on the Spectrum Rx. Just to see what was going on.

That's a great idea, I wish that there was a way to get feedback from the Futaba Rx's as well.

Once we get the new Weatronic system I doubt there will be any need for a head to head test any more.

Try dual FHSS with gps, data logging every darned thing possible to log onto an SD card. Yep take out the card, go home and see how your day went.

Now thats what I call a receiver.

Kiwi,

You are absolutely correct on that one. I will probably have to spring for one of those someday. You really get a lot of bang for your buck with them now, the 2.4 system will surely be the cat's pajamas. If I ever build my dream machine it will have a Weatronics in it.

Regards, Bill

Kiwi, be sure and get a new DSMJ system from JR Japan and test that one also !

Kiwi.....Just to let you know , i'm heading over to gerhards house ( USA distributor for weatronics ) either today or tomorrow and check out this new 2.4 Module and receiver power system he's working on. He lives just right down the road from me. I'm going to fill him in on what this thread is all about. I'm curious about a bunch of things , so i'm going to pick his brain the best i can.

P.S......i'm a complete idiot when it comes to these power systems and their capabilities but i will try my best to understand what the hell Gerhard is telling me.

Give me more info on this one please. I have not seen a thing about it. Is it modular, built in, any links please.

[sweetpea]

Kiwi-

I'm in favor of you starting a new thread once you get rolling on it.

a Head to Head of all 2.4 manufacturers.....sounds great.

I do think it requires all accessories with each one though ( I know; can get real expensive).

i.e. data logger for Spektrum and satellites, telemetry/XDP for XPS, whatever gadgets are avail for the others as well.
