When you use just one RX in large planes, you are overstressing your RX and servos (you've admitted this already). This greatly increases your risk because a system under stress is more likely to fail. By using a 2nd RX or a do-dad, your system will now work the way it is supposed to and will not be over stressed. The risk of failure has now been lessened in my opinion because things are working properly and are not over stressed.
So using a do-dad or 2nd RX actually decreases your chance of failure in my opinion.

Jim, At what amperage levels are the recievers over loaded? Are these amperage levels dependent on the reciever used (JR vs Futaba vs Hitec etc etc)? Is this imformation documented by the manufactuers as well as expected servo currents so we can determine when we are overstressing our recievers based on our planes configuration? I would like to know if I am overstressing my receiver in my Comp Arf Extra with JR digital 8611 servos?
Thanks for your help,
