Man... don't get frustrated. This single vs. dual RX setup is as controversial as abortion and Darwinism... well, maybe not that controversial, but close.

It really is up to what you are comfortable with.

I've seen guys land planes with 1/2 of the plane working... it's mushy but it's not a problem. The hard part would be if some if the servos didn't go to center (want failsafes set to neutral in a dual RX setup!!!)

As far as crossing the ailerons and elevators... no real proof either way. Mine are crossed, but it just came out neater in the wiring process.

Some guys run a jumper between the 2 RXs... pos and neg wires only, no signal wire. This way, if 1 reg, batt, or switch fails, then the other battery can power the whole plane. You won't know until you check batts between flights. You are basically creating 1 big power bus... just like plugging 2 batts into 1 RX. 1 RX failing shouldn't take down the other... the + and - contacts are simple strips of metal in the RX... nothing more. I haven't decided on this aspect.

I have both of my rudder servos plugged into channel 4... 1 on 1 RX, 1 on the other. They are rigged in an SWB self adjusting rudder tray... no matching required, and if 1 servo locks hard over the other servo can get the rudder back to center. That being said... 2 rudder servos may be overkill in a 33%, though I'm not familiar with your particular plane. My 35% is a good bit bigger than most (bigger than a carden 35%), and the rudder is huge.

Some argue that 2 RXs is 2x the chance of having a failure... then you may or may not get the plane back depending how good you are and how the RX failed. If you have 1 RX and it fails you have a 0% chance. It's all really up to you... which way do you think the stats play? Are you a gambling man?

One arguement for dual RXs is that it eliminates the need for a powerbox/power expander/etc... If you have 4 digis and 1 basic servo on each RX, AND you have 2-3plugs from your REG/batt going to EACH RX (each plug is only good for 3 Amps) then you really have no need for other power systems / expanders / etc... (failure points). My plane flies great without one (8 x 5955s, 1 x 8101, 1 x 525, across 2 RXs).

Look up the Weatronics system... may be the future of the hobby. Best of everything.

Happy deciding!!!
