Not trying to start an argument, but putting the ignition on a switch, separate from the IBEC, defeats its purpose. It IS the switch, all by itself. I have my LiFe battery behind the rear canopy hatch former for CG purposes; it doesn't come out easily. Therefore, I always leave the battery plugged in to the rx. It never drains the battery; you can turn the plane on and perform regular tx/rx functions without turning the ignition on: the IBEC comes with a red LED that tells you when the ignition is powered. I've been using this setup now for about a year, and it works great
Ace is correct on the LiFe battery usage; you cannot effectively load test them, so you have to measure, via recharge, what your setup uses, which I mentioned earlier (4-500mah usage per flight).
