Radio suggestions?? - Page 4

have you looked at the JR RS70 - it's pretty small and pretty cheap. it's a seven channel synth rx. or though maybe you need something smaller for HLG etc.

I have had good luck with the Polk Seeker 6. Small light and synth. I usually have them in stock.

Hello all, im just testing out the REX 4 MPD, and i was wondering if anyone knew what the two center pins are for, as there are 4 sets of output pins for the 4 servos and then there are 2 extra pins that have a little cover over them, what are they used for??

If you already have negative shift receivers, get the Futaba 9CAPS (if you are righthanded). Pos. shift receivers in your posession, go with the high end JR. What do others that you fly with use? They can help you with the programming.

I use the 9CAPS for all my planes. High quality, lots of support. I am sure that the same can be said for the JR. I like the Futaba because I can pull the CAMPAC module out, shove it into my buddies radio (must also be a 9CAPS) and dump in a plane template. I can also do the same thing to program my back up radio. Saves a ton of programming time.

In theroy the German radios are better for programming. That said, the Futaba covers everything that I want to do with a DLG or full house sailplane. It is sturdy and reliable. I like the synth. and it works with all the receivers that I have tried. I like to fly, not program.

I would encourage any pilot to give very serious consideration to the 2.4 GHz systems available.

For the orginal request of DLGs and Slope gliders I would believe the Spektrum DX7 is very capable for most slope and sport sailplane flying as well as most power plane uses. It can be used for competition 6 servo TD sailplanes but lacks a full complement of mixes usually desired for this type of flying. Some people have done a lot with the mixes to make up for the missing standard mixes. The transmitter, with receiver and servos goes for about $340 which is not bad!

JR's new 9303 2.4 GHz is a real winner combo for any kind of flying including competition TD sailplanes. This transmitter will do it all.

Thought I would also add a like to a thread about radio recommendations, but this one is about sailplane radios.

There are a lot of DLGs with carbon pods and canopys though. This apparently mixes very badly with 2.4. I want to try gliders, I want to try 2.4 but I am unsure of what to do. There are those DLGs without carbon pods, but it does really narrow the selection down. And wish Goldsmith and JR would jump on this problem.

aeajr · Jan 21, 2008, 10:10 PM

Many DLG pilots fly 2.4 GHz. When they have a carbon pod, IF they are Spektrum users they drill two holes through the pod and extend the antenna out. I imagine this would work with Futaba as well.

Reports seem to indicate that this works well with AR6000 and AR6100 receivers. You can do it with AR6200 too, but you would need 4 holes.

TRuss · Jan 22, 2008, 12:42 PM

I've read about this in the DS area. The attenae out the fuse was the first solution. It worked but ofcourse they were worried about aero effect at the speeds they are doing. I guess there are no aero problems using this method with HLG/DLG? If not, then I see no reason not to go 2.4 as I find DS fascinating but I am too financially and terrain challenged to do anymore than read about it. I'll probably start off with the DX7 and if my interest and skills in gliders continues then I guess I'll look at the 9303 on down the road.

Actually, the two whiskers have about as much drag as a good airfoiled stabilizer and the fin on a DLG. Small cylinders have very high drag coefficients at low Re.

I think mounting a remote receiver or antenna in the wing is the best solution for 2.4 in DLGs - unless it is a carbon or Disser wing of course...

That's what I thought. What is a Disser wing?

TRuss · Jan 22, 2008, 08:45 PM

There is a part of me that wants to try 2.4 and part that wants to say the hell with it. For those who have flown both; Can you really feel a difference in quickness. Does 2.4 feel more connected like they advertise or is it just hype. Because there are two JR XP8103s or less than $150 in the trader forums right now. There is another one brand new, never even turned on with an 8 or 9 channel rx for $250. How many of you are actually flying on 2.4?

aeajr · Jan 22, 2008, 10:14 PM

As an electic sailplane pilot using a module in my 9C, I don't notice any difference.

However I think the "connected" effect that people discuss is for the radios that are purpsoe built 2.4 systems. The DX7, the 9303 2.4, the Futaba 6EX.

Those do not have to go through a translation from the PPM stream in the radio into whatever is being transmitted. So things happen faster.

And, if you are a slow flyer or a thermal glider pilot, you may still not notice. If you are flying high speed planes, pattern, aerobatics on the slope, dynamic soaring, then you may notice a big difference.

vic20owner · Jan 22, 2008, 10:27 PM

I switched to 2.4 while i was flying helicopters because glitching with a helicopter is almost a guaranteed crash. I noticed a huge difference immediately in the response times between the 2.4ghz spektrum and my older Futaba 7CAP.

Now I'm using my DX7 in my DLG's. So far I haven't had any problems at all setting up flapperon mixes, but for a full house sailplane it may not be the best radio. I have never suffered a single glitch or lockout after a year of flying 2.4ghz in helicopters, ducted jets, and now recently DLG's.

TRuss · Jan 23, 2008, 12:48 PM

I'm really sweatin this too much. It's not like I'm in the market for a competition DLG. By the time I'm ready for that there should be some solutions to the carbon interference problems. I've read that some companies are putting kevlar windows in their carbon planes and I'm sure there will be other materials changes to meet the growing needs of 2.4 compatable airframes. Maybe the radio companies will even try to offer a solution instead of denying there is a problem at all.

aeajr · Jan 23, 2008, 08:53 PM

Truss, if you are looking at a DGL that has a carbon fuse, contact the maker and see if they will do a layup in S-Glass or Kevlar. The worst they can say is no.
