I understand redundency to the fullest,I fly a jet that has tons of redundant systems for a living(not as many as a 757) .There has to be a better reason why people are using 2 recievers. What fails in a reciever? Its solid state... overvoltage could do it maybe? No.. nothing can cause overvoltage in these things. The main reason rc airplanes crash because of a radio problem is 1)Radio interference 2)some nit-wit turns his radio on. Two problems that 2 recievers wont make a bit of difference in. I have heard of everything in an RC aircraft fail, except a receiver. I have been told its because the larger airplanes 35% and up need to split the load of all 15+ servos between 2 receivers because 1 reciever cant handle it all.(does that sound right) it does to me... You can have 10 receivers in your airplane, and still stick your plane in the dirt because your one and only transmitter just decided to bite the dust.I am ranting and raving, sorry, just looking for an excuse not to buy another reciever. It's cheap insurance I guess......well not really too cheap.....
