What kind of foamy requires 9 channels?If the plane is big enough to use so many channels just get a 9 ch. Rx (the AR6100 is not that good anyway)
opc orn:

Its not likely to be possible. The 9ch rx's have extra MCU's so the Ar6100 is not likely to have 9ch code in them. The DSX9 only transmits 7ch to the Ar6100 so you would also have to trick that into sending 9.

Thanks!
Plane is a scratchbuilt JAS, as of now ch 5 is retracts, ch 6 is motor forward /reverse
7 would be missile control.

the existing 9 ch is $$$$
so, not possible to re program the 6100? probably would make it the lightest
9ch rec?

If you only need ON/OFF control then you can put several functions on one channel.

For example, you could set up channel 5 to do both retracts and motor direction. The switches for both functions would be mixed into channel 5 in your tx, giving 4 different servo positions. Then you make a simple decoder which plugs into channel 5 on your rx, detects the 4 positions, and operates the appropriate device like so:-

1.00mS = retracts down, motor reverse
1.25mS = retracts down, motor forward
1.75mS = retracts up, motor forward
2.00mS = retracts up, motor reverse

You may not even need a decoder. Retract servos usually change over at ~1.5mS anyway, and motor control could be done with a servo operating microswitches via a cam (switches operated only at full deflection). If you don't need motor reverse when the retracts are up, nor missiles when they are down, then you might be able to use the following sequence:-

1.00mS = retracts down, motor reverse
1.25mS = retracts down, motor forward
1.75mS = retracts up, motor forward
2.00mS = retracts up, motor forward, fire missiles

Now you have a single channel controlling three functions!

thats a great suggestion!
retracts use a hacked hxt 500 wormdrive servo where the electronics serve only as brushed esc for the servo motor with microswitches for endpoints definition.
simply putting another servo parrallel with retracts and mixing in radio would probably work for missile control?
yes missiles need only work with gears up, motor fwd/ rev only gears down( to brake and taxi)
thanks!
