well just got back from first flight,boy what fun.i dont need much more than 1/3 throttle.or gas it and in less than 10 feet takeoff and straight up.it would hover at around 1/3 or a little more at 75 feet will be a few flights before i get down lower and try.i need to add more expo as when i gave it hard elevator or aileron the other would move a little bit but with this much surface it made it go where i did not wish it too.
