OK, In the last 3 days I went through 2 MM and the same results as RC. No matter what I did it would sustain forward flight at all , I tried the following to fix it
1. SW3 turned CCW just a bit , if you go to far the tail motor spins all the time.
2. Twist tail about 5 degrees CW
3. zip ties on the motors about 1 1/2 " long w/ 2 rubber weights on each one
4. Balance the blades
5. Throttle spring removed
The best it does is tilt forward a little and go about 1' then stop , no reverse at all. When I tried to go forward in either direction it just starts spinning out of control and crashes. Then I have to put the top gear back in place and try , try , and try again. Ahh forget it ,I am taking this thing back and getting another picco z , they had one left. This is for a friend and I can't expect her to pay $ 80.00 for something that wouldn't. She wanted a picco any way. I got her an AA w/upgraded Tx and she loves it...
