Scary. Ok I got it, If my setup draws more amps that the battery is rated for-then bad news. However since my Blade only draws 9 or 10 amps max, I shouldn't see a difference in performance between my cheap lipo rated at 7C and TP rated at 12C because I'm under the limit anyway. Incidently, my lipos never get hot, just mildly warm, so I know im not stressing them.

Also regarding vertical performance with symmetrical blades. If my throttle trim is all the way down, the blade barely climbs. With trim all the way up, I'm getting decent climb power-but I notice the motor is bogging a bit under the load. Is that the typical way of measuring performance? I rarely touch my throttle trim-always have had it all the way down. Should I be adjusting it more?
