Hi,I hope you can help me. My friends who fly planes are able to set their main needle by running the engine at max rpm with a prop and adjust the main needle.
My question is this. Is it OK to use a flat pitch curve of say zero degrees to ensure the helicopter will stay on the ground, and run the engine at max throttle and adjust the main needle as needed. Would this present a good enough load to the engine at max speed ?
Of course I would slow the engine to idle before making adjustments.

It seems everything with heli's is a bit harder than planks, and engine are no exception.

Heli's engines compared to planks:
Harder to cool
Usually run at max rpm
Requires good and lots of oil
Consume lots more fuel
Rings in place of ABC piston/cylinder construction
Much higher loading - 53" blades vs 10-12" blades
More complex carburetors

So I think you can see that heli's take a different approach on adjusting them. You can search and find a number of tutorials on how to set them up.
