I have a set up with Align 25esc/Align 420LF 3.2KW/ 2100 3s Lipoly and stock pinion. I am using a Futaba 9CHP set to:
Throttle Curve: 0/40/65/80/100
Pitch Curve: 0/15/30/45/60
Stock 315mm Woody blades
ESC Timing Medium
I used my heli stand to hold the heli down under power and have been unable to get more than 1700 rpm. Flying at this headspeed makes the heli sway & swing when hovering. If I reduce the pitch curve to
0/5/10/20/40 I get about 100 more RPM but no lift.
With the pictch set to zero on the curve I can get 2300 but as soon as I add some pitch RPM drops back down to its 1650-1700. I seem to be dancing around a solution I thought it may be the blades as they are so light?? any ideas?
