I bought one but gave it to a friend, and didnt even really look at it, does it have an actually receiver or is it one piece that has servos attached to it?...Your not leaving the battery plugged in are you?..he did that,not knowing any better and killed one of the batteries...is it just the motor or does anything on the plane work?..lastly are there batts in the transmitter?...does the motor/prop turn ok by hand?...Rog
