I doing final setup on a 35% Carden Extra 330S and I'm almost convinced that a dual receiver setup is the way to go. I've been using my A9 with a single Optima 9 and SmartFly PowerExpander Pro successfully in a 33% Sukhoi SU-31 for about a year. However, I really like the idea of true redundancy at less cost than a PowerExpander. I'll be using the following servos. Please see attached picture for my channel/switch/servo plan.

HS-7985MG x 4 - Ailerons
HS-7995TG x 2 - Elevator
HS-7980TH x 1 - Rudder
HS-5925 (or similar) x 1 - Throttle

Question 1:
Will this impact range at all? In other words, will the receivers step on each other?

Question 2:
I've been doing some research on this and I'm guessing that Scan Mode will NOT work with a dual receiver setup?

Question 3:
Does Hitec have an official position on running dual Optima receivers in a airplane? Any specific instructions regarding spacing between receivers, etc...?

Thanks!

There shouldn't be any problems using two receivers. Bind and use them in normal mode. The receiver you turn on first is the one you will get the battery voltage from on the display.

Thanks Brendan. I'm also planning to use a sensor station for head temps and RPM. If I plug it into the Optima 9 and always turn the Optima 9 on first, will I receive telemetry data as normal? Thanks.

Optima Transceiver (RX) - Dual Redundant receivers - The first turned on after the Transmitter will be the recognised telemetry sender.
