Hi Guys, thanks for the comments.
The transmitter and receiver type are in the title.
I want to check out the Lemon Stabiliser because the FunCub is stable so that I can learn how it may work with unstable planes.
Being a high wing aircraft I believe the Cub will benefit from aileron differential as per the build instructions.
I am trying to program dual aileron and separate flaps with a four servo wing.
The Ailerons are on AIL and AUX1, the Flaps (on a Y lead) are on AUX2, the Gear channel has the BEC connected (power only). I'm using a BEC because I have experienced brown-outs at our field with four servo models and this one has six servos.
According to the Lemon instructions on RC Groups this should be possible, but the Spektrum DX7 doesn't seem to want to play ball and offer me Flap settings with the Flaps on AUX2. The Stabilizer also cannot be switched in this configuration.
I may have to revert to a Y-lead on the Ailerons in order to get flaps (on AUX1) AND control the Stabiliser ON/OFF with the Gear channel, but I just wanted to check if others had been this way before and solved the problem.
Thanks for your comments anyway.
