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....

Radio TX's are not typically high amp drawing systems and the battery is typically securely attached, no vibrations/fuel exposure etc to kill the wires and switches. In an aircraft with a gazillion servos powering large, unbalanced flight controls at high speeds, dual batteries are a very good idea in my opinion. Not just for failure scenarios of a single battery cell or switch, but for the ability for a redundant battery to up the amp capability and voltage stability of the battery system.
