Pete,

You can set up a for 1 AIL, and still have two aileron servos on separate channels with aileron differential. Assign the AIL function to two channels - let's say channels 1 and 5, do the proper reversing and subtrimming (if needed) then setup the aileron differential with the endpoints for each channel.

OTOH there is an advantage to a 2 AIL setup as already mentioned (flaperons, and spoilerons become possible). And you are correct - even if the plane has a single aileron servo it won't hurt at all if the radio is set up for 2 AIL.

Or, give the freedom to change the wing type, which again is the logical thing, rather than trying to fit the change in by assigning channels. It appears that the tendancy is to change wing type, but you don't necessarily want to because it is more of a pain, to lose all the settings. At a bare minimum, I would ask that no servo reversing already made is returned to factory default. All other settings, I haven't really thought much about that, but leave my settings for reversals alone, please.

Can anyone tell me if people have been having good luck with the Orange RX in combination with the 8FG?

And I'm sure this has been asked, but, can you really feel a difference when going from a DX7 to 8FG?

What are you guys using for receivers in say 42", 60" and 72" sized planes? For that matter, how about in a small foamy?

This radio has a throttle curve, correct? That would be a big reason (or excuse) that I would buy one.

I have several Orange and Frsky RXs in my planes but only in some of my smaller and slower models, primarily foamies and park flyers. All my large, fast and expensive stuff has Futaba receivers in them. That being said, I have personally not noticed a difference, they all seem to fly just as well, never a glitch on any plane except twice when I flew planes with R6004FF receivers in them too far away (totally my fault as I way exceeded the specified range of the receiver), one I recovered, one went in.

Said it earlier in some post(s) - The FrSky clones work well with all FASST Tx.es (Ive only used/using the 7 and 8ch incl SP and S). Some issues thus, according to the known chinese QC: The cases have no heels moulded at the antennas positions, neither the HK orange nor FrSky (or re-labelled) boxes. Weve got a few Rx:es with one antenna off out of the box. Easy to fix but poor range if unnoticed.
The other issue has been if using analog servos. With the Rx on for some reason, and changing model memory (actually RF protocol in Tx) might cause the 8Ch to go back to default HS mode; unnoticed it will wear or burn servos.
Otherwise range is as good as (or better) with original stuff. Also FS has several options (depending on clone model); either hold, Tx set (and limited) or Rx set (all channels).

You talk about planes, as almost any Tx has curves for helis?
Yes - three curves If something called VPP (variable propeller pitch) is assigned to something.
Ive used curves eg. with car ESCs (funstuff and sponsons/aquaplanes) to switch between normal throttle stick behavior vs. REV on the lower half.
Theres no reason not to buy this Tx, those complains in former posts are things Id like to see in future updates!

I have used the OrangeRx 8 channel with my 8FG in a small electric for about two seasons and it worked perfect. Range was excellent and it never missed a beat. Unfortunately it sustained some damage after a crash due to an ESC failure. Have a couple of the new FrSky TFR6 units and they appear to work well. Have them in a couple small electrics, but have not had many flights yet. So far so good and I do like the fail safe options, although it has never kicked in that I am aware. As others have noted, on my larger glow powered planes I too only use genuine Futaba Rx. Not because I do not trust the FrSky units, but if I have over $1000 into a plane, the thought of using a $25 receiver to guide it does not sit comfortably with me. A few more bucks for a genuine Futaba receiver considering what I have in the plane is really not that significant in terms of cost.

There's no difference to be felt between DX7 and 8FG other than the 8FG being much lighter and slimmer, which I find to be quite significant. The real difference between them is in the number of channels (4+4 vs 8+6) and the programming capability (almost none vs. nearly limitless). And yes, there are curves for most everything.

Futaba offers 3 types of receivers:
- Single antenna with no failsafe which I use for park fliers and 60" sailplanes with great success.
- Dual antenna with no failsafe (R617) which offers unlimited range.
- Dual antenna with failsafe (3,8,14CH models) which are great anywhere you can afford them.

When I compare Futaba vs Spektrum or any othe radio, it is the bulletproof and reliable RF link which Futaba offers. No strings of satellite receivers required.

I offer this as another example of throttle revering when changing settings. I will be discussing with the Futaba reps at the WRAM show next Friday. Hopefully they will at least listen. If not, and no indication of caring, I will have to look for alternatives.

If nothing else, maybe this will simply serve as a reminder of what can happen. I get it, remove the prop, use a RX battery, etc. It still should not be allowed to happen, not when it's simple enough to address.

In 20 years of flying I've seen some of those with different brand of radios.

People die in car crashes everyday but if someone dies due to the car accelerates by itself (Toyota) is a different story.

The difference is that Toyotas don't accelerate by themselves, it's purely user error. Futabas on the other hand (excuse the pun) do indeed accelerate by themselves, so long as the user agrees that he is sure he wants to change some random minor unrelated mixer.
