Hello all.
Here comes the setup on my big Futura with Fasst Rx inside.
1 powerbox Champion RRS
1 Rx R6014HS (main receiver, main channels to powerbox + accessories on the Rx)
1 Rx R6008HS (spare receiver, only main channels to powerbox)
You don't need to have two identical Rx on the PB system.
My setup :
Channel 1 to 7 are the main flying controls, wich I want redundant : 2 channels elevator, 1 rudder, 2 aileron, 1 flap, 1 engine) + channel 8 for fail safe of RRS.
On the main Rx, channel 9 to 14 are accesories channels, wich don't need to redundant and don't need the full power of the powerbox : that is nose wheel steering, the ECU auxiliary, the gear electronic valve, the brake elctronic valve, and next the smoke system.
What should I put on the second receiver if it was a R6014HS one's ? Nothing as the Powerbox Champion is only redundant for 7 channels max...
My 2 cents...
And, no, I've never seen a switch in flight...
