I think Jeremy raises a good point. In my opinion a lot of jets have unnecessarily complicated dual systems and redundancy. It is like the old example of “Is a twin engine aircraft any safer then single engine aircraft?” Answer: only if it can fly on one engine. Otherwise the second engine has actually doubled the likely hood of failure, without adding any safety. (okay, it could extend the glide, but you get my point).

I do use dual batteries, and JRs multi Rx system, but that is the only redundancy I have in my Bandit. No power boxes and no switches, (just a Deans Plug for off/on). KISS, is my motto. If you eliminate the component, it cannot fail.

I do have a question though. Most people recommend a dual battery system of some sort inferring that our airborne batteries are a weak part of the system. Why then do we not insist on a dual battery for our transmitters.?? Surly the Tx battery is just as prone to sudden failure as the flight battery, with the same consequences. After all if the flight battery is correctly selected, sized and charged, it should be just as reliable as the Tx battery.. Just wondering why....
