The main point of this is there is a lot of misinformation out there about why you MUST run 2 receivers. If you CHOOSE to run 2 receivers that's fine.. that's up to you. I choose to run 1, and accept whatever risks there may be with a single point of failure. I also run dual batteries through dual switches into this one receiver. The reality of electronics is once something passes a burn-in test, it's unlikely it will fail through non-abuse. I see a lot of VERY poor installations these days that could easily contribute to receiver failure. People have gotten away from wrapping receivers in foam and softly mounting them for some reason. I see receivers velcro'd to plywood plates and zip-tied to a thin piece of foam and so forth. Then vibration causes a receiver to break and they blame the receiver.
I think people need to get back to good installation practices.
Very well said. I was having just this same conversation this past Sunday. A fellow at my field has his batteries zip-tied directly to his wing tube in a 33% plane and he has his dual receivers attached with velcro to the floor of the plane. No foam in sight.
A plane I recently purchased was the same. Batteries in direct contact with the frame of the plane. Seems to have become a very common practice. A little foam goes a long way towards eliminating many of the "failures" that people have.
