I don't use them on any of the 50cc planes, and didn't go to one on the 111cc plane (36% Katana) as I don't have digital servos, and run an AR 9100 reciever that has redundant power feeds built in.
Ah Ha, thanks!
One of our old club members (Been flying RC since 1959!) uses the top of the line Spektrum receiver on his various turbine models. Nice that the receiver has dual battery inputs, eliminating the need for the Powerbox or similar type of system.
