Thanks for the info Mike. George had a good question.
I will call Futaba today and ask Ben Baxter that same question. I believe in "over kill" since I lost a plane a few years ago because of aileron servos that had a signal problem.
I switch from 50 MHZ and 2.4 depending on what plane I am flying by changing the module on my 14 MZ. My older fleet is on 50 and the newer models are on 2.4
Just finished my 86 er yesterday and I am using a duralite 40/16 powerbox in it with 123 batteries all around using the R608FS rcvr and S9156 servos on the control surfaces
