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....

Because you have real time information on the transmitter battery status on the display, and even a warming beeper in case of a sudden voltage drop. Also the tx battery and connector is not exposed to the vibration and "g" forces you normally found inside a airframe.
