I just flew my wingo for the frist time sunday. What a blast. alittle knee knoking at frist but i settled in. any way i know you are suppose to drain your batts down every so offten but is it a good idea to use the plane servo,motor ect to do it?I read about not draing too much because it is hard on them want to take care of these they aren't cheap. any advice would be greatly appreciated. thanks alot!
