Hi all. Probably another dumm question. Finally got the 450 running smoothly and into hover practice. Although the heli comes off the ground nice and smoothly with just a touch of right applied. I find I am leaning on the stick all the time to get it from drifting off to the left. Do I trim out like I would an aircraft with the TX trims or do I do it mechanically i.e. adjust the pitch and aileron push rods. The swash plate is level and the helicopter flies nicely apart from the drifting to the left. One more thing what sort of flight times should I be getting. I'm using Turnighy 2.2 30 to 40 discharge rate. I was going for 6 minutes but after the rebuild and the last flight it floated down from 12 feet or so when the battery give out after four and half minutes. Cheers and thanks in advance.
