Wondering what the AMP draw is on a standard ball bearing servo while in motion under a load running with a 6 volt receiver battery.

Thanks

There's no way to tell, because there isn't a "standard" servo. Most servos will draw up to 3 Amps when stalled. Most are quite a bit lower. "Under load" can mean many things, because the load is always changing. You need to use an on-board recording meter to see what your current load is when you fly your model. Then, you can determine the average current pulled by your system.
