Futaba Power Expander and 12FG
Had an interesting thing happen last nite while setting up my 100cc YAK.
I'm using the new FASST 12FG and the R6014FS in an older Futaba Power expander.
This new setup will use 2 Hitec 5955's in a rudder tray sharing the rudder channel, and an analog Throttle servo. All other surfaces use Hitec 5945's.
The rudder channel was originally assigned by the Radio to channel 3 and Throttle to channel 6 by default...the PE has only 2 servo connections on channel 3 and 4 servo connections on channel 6.
With one 5955 servo plugged in, no Problems at all....but once the secound 5955 servo was plugged in, the servos went nuts and started jittering.
After re-assigning the Rudder to channel 6 and placing the throttle on channel 3, all seems fine.
Might you have any insight as to why the 3rd channel on the PE would not accept 2 5955's sharing that channel, but channel 6 takes the 2 servos with No Issues?
The PE was working flawlessly on a 100cc plane with a 72mhz R319 previous to this setup, but as you know, the Futaba 9CAP assigns the throttle to channel 3 and I never had more than 1 servo connected.
