Hi people,

I'm working on a University project for a competion involving autonomous flight (but that's another story) and we've got 8 digital servos (Hitec 5925) on an aircraft. What batteries would be best? Due to the design of this turbofan machine, the servos will all be constantly stressed quite close to their max. (testing will reveal if we need stronger servos). The batteries will also be driving 4 spark plugs. Would NiCad batteries be enough? And if so, what's the minimum amperage I'd be looking for? The voltage to the servos will be regulated at 5 volts since it first enters a PWM board which controls the servos.

Thanks,

Marcus
