I was one of these guys that follow the traditional setup, one battery one receiver. Ontil i received a lockout after regaining control for some unknown reason and landed my mind was shot shaking and nervous i was done for that day. Thats when I Install two receiver and two battery. Another day i was in a flying a knife edge config at the same spot the rudder went neutral then back to full deflection. I must admit that flield is plague with RF problems. For me any Turbine jet or RC plane over 16lb should use two batterys (Opinional two receiver) Sometime keeping it simple does not mean using a double A batterys for the receiver or CA elevator servos formers.

Just my opinion
