OOOOooooo somewhere I missed thinking about the 10 servos issue...

An option that should be considered with that much load... dual Recievers. You gain some significant safety from this.

In case one RX fails, there is a high probablility of being able to save the aircraft. If you can't save it... you can at least steer it so the impact is in a safer location and possibly minimize damage.

You split the RX loads and thus take load off the switch harness . (one of the weakest links in the RX power system) With just 5 servos per RX... and thus 5 per switch harness you have appx 55% the current demand on the switch.

You would automaticly be using a form of dual battery system. If the rolls became imballanced, or significant roll coupling occurred with elevator, you would KNOW one RX's power was failing and still have a good chance at successful landing. (rather than... Uh-oh, sluggish elevator... oops no control at all...[:-] SMACK! )

There was a series of tests on dual RX systems done a few years ago... the test plane wa set up such that one RX could be shut down by switched channel on the other RX. (unused on the RX being sht down) He put the sticks in the coners, and shut off the second RX disabling 1 elevator half and one aileron (among other things) at full deflection. He then safely landed the model! Choosing the surfaces to be controlled by each RX was the key to that success.
