Hi all,I am building a hobbyking fpv 168 airframe for use with ardupilot after successfully using it in my hz supercub for the last few months.The new plane has loads of space, but is very tail heavy and needs lots of weight in the nose. This got me thinking about power sources for ardupilot mega and the servos. Normally you would use the BEC, but to add a bit of weight to the nose i was thinking about using a reciever battery pack (NiMH 4.7v 1500mah) to power the system. I would obviously still have a large Lipo for the motor.Would this be a good way to go, or would the BEC still be better? The plane has 5 servos for flying surfaces (flaps,alerons, rudder) and one for wheel steering -6 in total.RegardsJames

the power consumption on of the APM and the servos is not that high. the supply is clean enough as ur using batteries , however u need to mesure how much flying time u can get out of the 1500 NiMH :).

Well , i see the advantage of having slightly more flying time :) other than that i dnt see any other reason to do it.
