Idea for more reliable switch
Hi,
I use two batteries and two switches in all my big birds. I just plug into two channels of the receiver, you can use a Y harness if you need space to plug in the extra battery.
I know for a fact that this arrangement has saved my birds on more than one occasion. After landing and getting ready for the next flight on several ocassions I have found one of the systems to be non functional, either from battery failure, switch failure or lead failure. The point is the dual battery arrangement saved the bird.
My 2 cents
