Flying upside down with a helicopter.
After lift off, Turn the copter over reduce throttle to zero and fly on. Every thing is reversed. Even though you have the buttons on some of the transmitters to reverse the reverse, Do not, Try and get use to flying where every thing is reversed. Remember away and towards you are always backward except upside down.
After I play with my FMS for a while, I won't be able to fly my RC models any more.
