On Off Switch Solution
Crosswind, true I also position my switches on both side's of the plane so that they are off in the forward position. and on the greatplanes push/pull switch I install it so that the switch is pushed in when on.
KiteGent, any single switch can fail, even the ones that are not supposed to! can fail. Nothing you can do is 100% even my duel switch method is not fool proof. Now if I were to install two of those reliaswitch's then life would be even better.
To have a true redundant system would be to have two fail safe switches and two batteries with switches in the forward position when off. For a kicker lets add another receiver.
