This question has been asked before but never answered as far as I could determine, and it's not in the manual:
Is it OK to plug in the USB cable to the APM2 while it is powered up with a LiPo?
The manual addresses powering up the RC receiver separately from the servos but that is not what I'm asking. I want to configure the APM2 with the MP software while it's in the aircraft with the USB. If I do not connect the LiPo also, the digital servo will consume a lot of current, probably too much for the USB to supply. So is it safe to have power from both the USB and LiPo at the same time or will it break something?
Thanks
Alex
