I recently purchased the MSA-10 and will be using four aileron servos on it. I noticed in another post that you can use one channel to drive the four servos for two ailerons on each side. My question is this, I plugged the four servos in and I reversed two of them in order to make them go in the same direction. I used only 1 channel for this. Is this "OK" or is this a bad idea? It is for a large scale Bipe that is powered by 4 aileron servos, 1 in each aileron. Whats the difference of having the two MSA-10s rather than the one? I am a little confused by this because I have never used the MSA-10. In the directions it states that I should use 2 of these, should I be doing that?
