After checking the servos I have available I’m going to install the following:
Aileron 2x aitrtronics 94141 (45)
Elevator Airtronics 94737 (57)
Rudder JR DS821 (88)
Flaps Airtronics 94102 (50)
Throttle Futaba 3003 –
Retracts Airtronics 94461 –
Spoiler:
Assuming the spoiler worked in unison with the flap to allow air through the glycol cooler and when the flaps come down it follows. To accomplish this I will probably install separate servo for spoiler. But have no idea how to work out the slaving/mixing on a seven channel rx, may have to spring for a 9 channel rx.
