RE: Servos
Just make sure that you don't have end point binds. That's the kiss of death for a lot of the 2.4GHz systems as this will definitely put a heck of a load on the servo and thus the battery pack, and could - read COULD - drag it down below the receiver threshold voltage.
The throttle linkage should move freely from idle-stop to full wide open without any binds at all.
