I'm in the process of building a HobbyClub Danny with hopes of using a 2.4GhZ system in it. There's a fair amount of carbon fiber in the plane. CF uni in-between layers of fiberglass in the pod. All CF weave in the boom. CF spars, CF / Kevlar weave in the D-Tube & Ailerons+Flaps, AND cf uni cap-strips on the ribs. My plan is to stuff the RX up in the wing between ribs, and add 2 more satellites between other ribs. I have no idea if this will work well enough for full range. :rolleyes:

Question: What modern TD airframes have you sucessfully used 2.4GhZ on? How did you install the gear? Obviously, nostalgia & woodies are OK, but have you specked out a late model moldie with 2.4, or an AVA type airframe, or whatever ??

I think this list would be useful for many prospective 2.4 buyers looking to fly TD.
Thanks,
RD

Avas are coming now 2.4 friendly if you want.. I would ask Alberto if they are following suit..
Also check some of the 2.4 threads for hints to use 2.4 in carbon fuzes. Brian

I have successfully installed a 2.4GHz RX in a all carbon fuse Gladiator II DLG. Somewhere on RC Groups there is a thread about 2.4GHz and carbon fuses. Trick is to lay a wire next to the antenna wire that is an exact multiple of wavelengths. You then run the wire out the fuse (though an opening or hole) and make sure one wavelength is hanging out. I seem to recall you wanted multiples of 31mm, but not sure.

In any case I did this with my GII DLG and an AR6100 RX. Range test is fine, and I have had zero issues flying this setup. Before the mod it wouldn't even work across the room.

I've just ordered an Organic 2.5E which I will use with the AR7000. Plan is to do the above trick for the RX in the pod, and place the satellite RX in the wing.

When XPS starts making end plug Rx's, could be flush mounted, single annt. straight up? I know the guys at XPS are working on it big time.

There is now a 2.4 friendly pod for the Supra at www.kennedycomposites.com

I will be trying 2.4 in my Thermal Dancer over the Christmas holidays. This is a mostly Kevlar pod.

Also, Pike Perfect has one available now too I believe.

Hey Marc, send me your radio and I'll test it in my Thermal Dancer. Just send the whole Zenith, I take the radio out for you. :-)

At the Visalia Fall Festival, Larry Jolly Flew a Danny with a JR 9303 2.4 radio, the only mod was he made up a glass canopy, got rid of the full carbon canopy, the receivers were mounted in the canopy opening area, I timed for him and never sew a glitch.

The 2.4 antenna's are very short compared to 72. All you need is some fuse space that is not 100% carbon. As mentioned, several models now are coming with glass nose cones. The carbon up front was just for show anyway.

We, Kennedy Composites, have almost our entire line of sailplanes and electrics 2.4 gHz friendly. As the leader in sailplane technology the Supras, AVAs, and Blaster 2s have been flying successfully all summer using the Specktrum line of 2.4 radios.

We offer retro fit fuselages you can use to update your current sailplane at a modest cost.

I have flown the AR7000 in my Psyko. Fuselage is all fiberglass on that model and the wing is pretty much all carbon ahead of the flaps (it is a bagged wing).

One thing I noticed (and this could be a coincidence, or perhaps not) is in the Psyko when I moved over from JR700 to the AR7000 the flap servos used to buzz when I held the plane with the transmitter in my other hand (like when launching, carrying it, etc.). They don't do that near as much with the AR7000.

I have done a little testing of the AR7000 in my Alllegro Lite (kevlar fuselage with carbon tow along the sides) but have not really flown it yet.
