Bear with me..........

I have two elevator servos. They are mounted symetrically, I do not have or want to buy a servo reverser.

I want to use the master-slave feature to make the elevator halves work in unison. Channel 5 is not used in the model.

I will be using channel 6 for the aileron halves, later. I have programmed this in the past. It worked fine.

So, that leaves channel 5 to be my slave. I want to use 2 as the master and 5 as the slave. I want the switch for 5 to do nothing. I can only get movement of channel 5 but not symetrical movement with channel 2. The switch runs the throw to extremes of up or down elevator.

After 3-beers and a couple hours I am stumped.

Anyone.......Anyone??

Thanks,

Scot

After carefull research I figures out that:

1. The 6ex 2.4 does not have that function. I can get it to work but, not well. The slave channel does not respond to the master's trim.

2. If I use a Y-harnes I can do better. I flipped over one servo horn. Then, by selecting servo horns and adjusting the linkage I got a good result.

3. I lost another excuse to buy an 8FG Super.

Any master- slave combo does not respond to trim changes. I would Y cord your ailerons as well for that reason. The EX is a great radio if a little limited on its programing.

6EX has flaperon mix, so trim will work with independent ailerons.

Your right, but I can't see any advantage in it, unless you just like to home run everything in case of wiring failure etc.

Ease of setup, ability to program aileron differential and/or flaperons (my new Sig 1/5th scale Cub calls for 50% differential) are a few reasons to use two channels for ailerons. Personally, I would avoid using a Y harness.

Yeah, what they said. I run the ailerons off two different slots in the RX. By doing that you can program differental. You add add flaperons and mix in the down elevator. I did that on a Bridi Big Bee. I can't say that the flaperons do anything usefull though. The flaps are simply on or off and I do not like that. A three position swith or knob would be better. Aileron differental is real important on some models. I have a 1/4 scale Aeronca Champ. I needs lots of differental and rudder mixed in. One you get all of that set up right it turns in a very pretty coordinated way. If you try to turn it with symetrical ailern throws it does not turn. It just yaws real bad.

The 6ex 2.4 seemed like a lot of radio when I got it. Now I am feeling it's limitations. I will buy an 8FG when I can. Anyone know if the 8FG will play with the 6ex 2.4 via a buddy chord?

I have always done my differential mechanically, never tried flapperons.
