thanks guys.

if i go 2 wing servos do i need a dedicated channel for each (i.e. 5 channel radio) or can i somehow hook them both up to the same channel (i.e. 4 channel radio) and reverse the direction of one etc.?

also, do you mention programmable radio servos for a specific reason or just a general preference? the whole pcm vs. ppm thing has me confused. i know there is a lot on the boards here about that but what i don't understand is how in the radio descriptions they mention for instance that the 9caf also has pcm capabilities (i think) and the 9cap has ppm capabilities. if that's the case what difference does it make which one you get?

thanks again,
