My father still has the one I flew. I will see if he can take some pics of the servo setup and send em to me.
I can say that you attach the servos to each other in pairs with the output shafts on opposite sides and install them in between the square stock pieces then cable tie them in. One set goes before those plates in between them and the tank, one set behind those plates. The aileron servo arm is detached from the servo each time you remove the wing leaving it with the pushrods which are attached with quick connectors. The throttle, rudder, and elevator servos remain attached.

Anyway, when my dad sends me the pics, I will post em here. His was originally a trike but while I had it, I converted it to a taildragger and thats how it remained.

I have the biplane version but it had a pretty bad wreck and is still being repaired.
