Seems like with all the things that require the bird turned on to do while on the ground; from transferring HD footage to the Ipad, to accessing basic flight settings and parameters or using the simulator. There would be some sort of plug in power adaptor, cycling Lipo's without leaving the ground seems sacrilegious... Anyone heard of anything like this? or tried to make one? I guess one could take a worn out batt, and replace the cells with wires to a transformer, or 4... Surely with some basic electronics knowledge it wouldn't be too hard.
