Currently have two TD gliders using Stylus tx on 72mHz with original Airtronics rf modules. Receivers are both Hitec Fusion 9. (they were on sale for $18 each!!!, normally much more). Now have two Airtronics FHSS-1 modules and thinking of switching over, but I have a lot of 72 mHz rx's and not so many on 2.4gHz. I should explore the programming in more depth to get another flight mode setting in there. Right now I have reflex, normal, launch. Will probably go to SD10g at some point.

I'm just now maxing out my Optic 6 Sport. The main thing lacking is flap/ail mix for full span ailerons/camber. No biggie though... at least not yet.

I'm hoping over this winter i'll be one of the lucky ones to bag a Futaba 9C Super 2.4 for a decent price...say, $250?

I think you realize that the 9C Super was a 72 MHz radio and was not sold as a 2.4 radio. So you will have to add 2.4. It is pretty easy to do. Or you have to find one where they have already upgraded to 2.4.

This article may be helpful.

yup. I already have a "dial-a-crash" ready to go. I've many many receivers and a smorgasborg of various crystals. I'd slowly gather 2.4 rx's as well.

I have my old 9C Super on FrSky 2.4 Telemetry available. It has no issues other than being a little old and dirty. I picked up a nearly new 9C Super a little while back, so my original has become a spare. I occasionally use it as a wireless buddy box using a FrSky CPPM receiver. (Got to love halving a buddy box that can be a mile away. LOL) Can let it go for $260 shipped. Drop me a PM if interested.

Many think you need a high end radio to fly full house gliders, but you don't. I had not looked at the Optic 6 sport in a long time. I am impressed with the glider mixes is contains for such a low cost radio. I see aileron diff, camber and crow mixing. Impressive.

Interested in what full house glider you are flying on the Optic 6 sport. What mixes, if any, are you using?

It's a Spider 60 carbon. Using snap flaps, ail/rud, crow, and reflex/normal/camber 3-way switch-mix with elevator compensation.

However, it's just independent flap and aileron operation. I.E. reflex/camber is just the flap part of T.E. without the ailerons following suit. Vice versa with ailerons only without the flaps also working as ailerons.
Is it really necessary? No. Would it be nice to have? Sure.

Additionally, a 9c would mean I could do both FM and 2.4 and not have to carry two transmitters with multiple planes.

YMMV ...
You're entitled to your opinion, feeling good about crashing with brand name stuff as opposed to having no problems whatsoever with "cheap" chinese stuff??? My "brand" stuff goes out the door, I prefer reliability over "name"...Moreover, the Open9X software has possibilities none of the brand stuff was able to give me all these years...But hey, to each his own...

Thanks. After your post I pulled up the manual. I was quite impressed with the mixes this radio has at such a low price. I was not aware of its capabilities.

Ailerons as part of camber and reflex is better, but necessary? No.

I looked at the post at the link you provided. What I seem to get from your post is, even if you spend money on a high end brand name radio it can still fail on you which can lead to the loss of a plane.

My philosophy is that every take-off is an act of faith and every landing a moment of relief. No matter who you buy your equipment from, they won't gurantee you will never have a problem and they won't replace your plane if the problem causes a crash.

You do your research, draw your own conclusions, then do what is comfortable for you.

I figured this was as good a thread as any to ask this question without sucking bandwidth with a new thread.

For those A9 folks...is a 7ch rx adequate or 9ch required for a 4 servo wing with full TE control. I'm assuming each servo needs its own rx plug in order for full span aileron/flaps.

I use an A9 with a 7 channel receiver. 4 servos for the wing, 2 for the tail, and 1 spot for the ESC. That's the 7.
