RE: Airtronics/Futaba
Futaba & JR/Hitec will work with the blue "Z" receiver, however you will need to remove the tab from the Futaba plug. No need to change the wires. The signal (white) wire should be next to the channel numbers on the receiver.
BEC (battery eliminator circuit) is part of the speed controller, not the receiver.
The slot marked "B/7" on the receiver is for 7th channel. You have to use a y-harness to hook-up channel 7 and the battery. I am not sure if the 92765 is 6 or 7 channel. I think 7.
