I'm having trouble getting my engine to run properly. I'm new to helis and don't know much about tuning them. I can fly it fine and even tic-toc it some but I don't understand tuning the engine.

Heres my problem...

The engine runs fine in idle up for a while. When I go back to normal after throwing it around the idle seems to scream. The smoke gets less dense and the stinking head speed is screaming. I've change the pitch curves and throttle curves but I can't seem to get this darn engine to run right. I've loctited the "hidden" needle and moved the mixture needle and high speed needle everywhere without any luck.

Any thoughts? I'm about to just give up and buy an OS 50...

ARGHHHHHHHH...

Sounds like the low speed is to lean. Once you fatten up the low end, you may have to go back and re-adjust the high end. If the two dont work together, it will never run right. It could be many different things but Id start with the low end

hi
Hover the model and adjust low end until model hovers without bobbing up and down.. (no vibes in tank, etc)..

THEN

do power climbouts and adjust high end accordingly..

I think your "transition" between two needles are off.

Thats what I do. It worked for me.

Which low end needle? The one behind the throttle lever or the mixture screw next to the high needle?

Thank you for your help. This is my first gas heli and I love it.

I believe I found it.

I called a technician and he told me to start at 1 3/4 out on low (hidden needle), flush with mixture screw and 3 turns out on high. While checking the hidden low needle I noticed my throttle servo wasn't opening the carb all the way. Ahhhhhh.... I was trying to tune the engine while it was 3/4 open. Well, it flew great today. I did have to turn in the mixture screw a bit to keep it running on the ground and I leaned out the top end a little too.

Thank you all for your help.

Put an OS carb on the 53 and no more worries. Mine is a power house with a smoothie pipe.
