This topic has been beaten a couple of times. I still cant decide whats best. Receiver failure is a remote possibilty, but a possibilty all the same. I am running one airplane on 1 receiver and a powerbox, and another on 2 receivers. Single receiver is cheaper, and easier to install. With the powerbox I get battery redundancy, signal amplification, and short circuit protection (IMO the most likely cause of receiver failure). With dual receivers I get the piece of mind that if one fails I still have a good chance of recovering the airplane in big pieces rather than little ones. It was a little more complex to wire up, not too bad, the antenna routing takes a little more thought, and some folks claim you lose range - I dont notice it if its true. There is no short circuit protection were a wire to fray or break under vibration - thus the wiring gets a lot more scrutiny than the other between flights - on the bright side there is battery redundancy. If DA ever gets the DPSI Twin in stock, I think thats gonna be the cats meow, hands down the most bulletproof setup. True receiver, and electrical redundancy, all in one box, and it will be going into my dual receiver setup.

Both setups are rock solid. But without a powerbox I would certainly do dual receivers.
