Okay... I am finally moving up to a Vario Benzine Acrobatic Gasser helicopter. However, I have only used Spektrum's DX7 radio/receiver.

Anyway, my friend doing the build has advised me that the Acrobat is designed for the 4 point ccpm and that the DX7 will not do the 4 point ccpm mixing.

I did some research and found the JR X9303 will do the 4 point ccpm. Initially, I was looking at the Futaba 10CHG 2.4GHz... but got into a conversation with a veteran gasser flyer who advised against the Futaba radio.

I know people could debate which radio is best until the cows come home... But I just need to know if the JR X9303 would be a decent choice for the Vario Gasser?

I'm sure the Futaba would work okay, but I've heard the little joystick toggle for the lcd screen sticks after a while. I'm leaning towards the JR radio at this point, but I wanted to get input from more experienced heli flyers before spending $629.99 on a new radio.

Keep in mind... I am spending $3,300 on this heli build and truly need a quality radio to match the quality of a helicopter this nice. I appreciate your insight, knowledge and experience. Thanks.

For what it is worth, I am running the Futaba 10CHG on my Predator Gasser and love the radio. Never had a problem with the joystick or any other problem. I fly Futaba and had the 12FG but I prefer the 10CHG ease of programming. All the radios are fine for the gasser, just depends on what you like I guess.

Are you referring to mechanical CCPM with balls on the swash to servos x4? (i.e.: one ball at 0 deg, 90 deg, 180 deg n 270 deg?) If so, the DX7 can do that. I have an old Trex 450XL HDE setup like that and running on my DX7. I had it set at Norm on the swash menu.

Or if you wanted to spend for a new tx/rx Why not try the new AIrtronics SD-10G or the new Hitec Aurora. Or splurge for a JR 12 or Futaba 14? ANy radio will be good. Your other best bet is to see what most of the local flyers at your flying field are using. Then you have more people there for "tech support."

This is the negative input I got about the Futaba radio:

While you can get by with 7 channels, you really need 8 to do it right.

I don't like Futaba radios, especially the new 10 channel, it just looks and feels cheap. Also the little rocket knob will start to stick to the side in no time.

[U]I think you'd be better off with a JR radio[/U], I think 12 channels is overkill but the 9 channel system should be perfect. Sell your 7 channel while you're at it and get yourself a 9 channel and you'll be set for life. I'm flying old 8 channel 72Mhz radios still to this day, a JR 388 and a JR 8103 with no issues with my gassers.

Again... I'd prefer to get input about the JR radio because my only experience has been with the Spektrum DX7 (which has been good).

It is just that the guy doing the build at Taylor Made helicopters has said, "Acrobat is designed for the 4 point ccpm and that the DX7 will not do the 4 point ccpm mixing." Therefore I have to upgrade to a better quality radio. Of course, with a $629.99 purchase price on a new JR radio, I want to do my homework before forking out that kind of money.

The Vario is an expensive heli... therefore I'd feel better having a quality radio to fly it. Let me know what you think and your experiences with the JR and Futaba radios. Thanks!

I use a Futaba 12FGH. I've been a Futaba user, JR user and Airtronics user. For whatever reason I've liked the Futaba transmitters the best. I fly a Vario Benzine Acrobatic and 2 Min Air Spectra G's and the radio is up to the task for everything I do in this hobby.

from a futaba 10cg owner, i've not had any problems with it but i haven't had it long enough to find any (i've only used it for 3 months) my 9c has never let me down

as you have a dx7 i would go for the 9ch jr 2.4
as you can use the rx's from the dx7 with the jr radio
the jr did have a cable route fault but this should be corrected on the new sets

you could go 120* 3 servo eccpm with the swash and still use the dx7
but me i'd go the 4 servo eccpm with it

JR 9303

As stated you can use the rx's from your DX7..
Secondly, you will have no problem going to the 9303 from the DX7 since mostprograming is the same.... And you will have NO problem with the JR equipment, but if for some reason, you do need them, the service is outstanding....I have flown JR in just about every type of heli available, including me 3 Vario Benzin's both pod and boom and scalers!!!!
And it sounds as if your builder is more comfortable with the JR programming...
Good Luck Stan

Doing a google search on the heli you are building, you don't need to use 4 servo eccpm. It does have the capability for being set up using a 120 deg 3 servo eccpm. Your current radio is good for this setup. The spektrum radio is manufactured for Horizon by JR too. So, stick with JR.

One last thing, are you going to build this heli, or pay someone to do it for you? IMHO, building your own heli is the best way to learn how to maintain it. That way, you will know how to take it apart when you crash it. YMMV. Also, the satisfaction of seeing something that you built fly is so much better, IMHO.

The Futaba 10c would be a great choice. I had my hands on one and absolutely loved it. The display is crisp and easy to read. The radio is one of the fastest out there.

The 9303 will work fine. I have set up lots of 4 point gassers on both JR and Futaba with no complaints.

If this is your first four point, just keep in mind that swash binding is something to watch for. It doesn't exist in three point CCPM, (that would be interaction). When you're done with your setup, just pop a ball link off the awash and check that the link still centers on the ball throughout your collective travel.

Have fun!
