I am having lots of problems tuning my OS 37 w/ MP2 and 15% Coolpower. The heli ran decent with the stock TT39 but this OS 37 is a pain in the butt to tune. I have numerous car/trucks and have no problem tuning all those OS motors but this heli motor does not want to rev up with out cutting out/bogging out. Ive tried super rich/super lean/right were the book says, nothing lets it get to a hover, close though. I am using OS 8 plugs. Im gonna try some fresher gas and OS A3 plug. What are you guys using for needle settings on this motor? I couldnt get the HS over about 1500 because she would cut out/bog right at that point. Throttle curve is like 32/42/52/62/100. Pitch is -2/9 or so.
