Independent tests prove lack of frequency hopping with XPS

[Kiwi]

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.

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.

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.

[dirtybird]

Please include receiver sensitivity test in dbm.

If you guys are confused about any of the technical mumbo-jumbo in this thread, just look at this chart, it should clear everything up:

I love it! ROTFL!

LMAO. with the chart.

OK it looks like the feild is growing in the 2.4Ghz markets and I have a list of what is available today or known to be available within the next six months. Guys if you can add to it anything you know please.

But what is obviously apparent is that to do a heads up on all this will need financing from the state department. There is just too much and too many to try and do as part time after work thing.

The systems available that I have found so far are:

FASST
SPEKTRUM DSM
SPEKTRUM DSM2
SPEKTRUM DSMJ
XPS
AIRTRONICS
ASSAN
WEATRONIC
IMAC
WFLY

I am sure to have missed some but when you put that pile of equipment together plus the fact that some of them are not modular and that means buying a radio as well it just does not make sense for me to do it or even attempt it.

But before we close the case on this is it possible among the brains trust we have interested here to make some sort of onboard data logger that we could pass round to different guys. Not a logger looking at your receiver, rather something that only looks at your Tx and the noise environment in your area. Sort of like a small portable frequency scanner that logs what it sees.

I am thinking of something you place in your model and go fly. After the flight you have a look at what was going on.

I see a small device like that having great merit for guys who think they have a dirty area to fly in, it could even be used to check the site before an event or something.

Scanning from the ground is pretty much useless if you want to see your flying field environment.

So what would it take to make something simple and easy to use for this, or am I on the wrong track completely.

YoMan's example has a very interesting idea that I have been thinking about:

There is no need to have satellite receivers if you can have quick disconnect satellite antennas - like in the wings.

Is there a micro quick disconnect coax connector sort of like the ubiquitous bayonet connector on the 14 MZ antenna ? It would have to be good for 1000 insertions instead of the 30 for U.FL.

Kiwi, If you are going to include DSM, DSM2, DSMJ then shouldn't you include FASST 7 CH and FASST MULT CH modes ? They are not the same protocol.

Now that is a complicated system of levers and pulleys
