I just received a Heli-Max EC145 and I am trying to fly it with my new Tactic TTX650. I think I programed the transmitter correctly but when I start to add power the rear rotor starts spinning before the main rotor, causing the heli to spin on the ground. As this is my first CP heli I have no clue whats up. Even if I can get it to lift off all it does is spin. What did I do wrong? Is there a problem with the heli? I used the info in the manual for the setup but I got lost when it came time for a lot of it as the transmitter and the manual don't speak the same language to me. Again this is my first CP heli and the first time I have tried the Tactic TTX650 radio. Thanks for your help.
