Which heli you got I just completely rebuilt my Blade CP/CP2 mix with BL and readjusted all the pitch and swash etc.
Are you using a after market TX as well..

I'm new to this hobby as well so my information might not be right.

What I do is set the Idle on. Motor and tail disconnected.

Move the throttle stick to Middle. Throttle trim up to 0 as well.

Then set the pitch to 0.

then check the pitch at Full should be around 12+
then checkt he down should be around 10-

If you're using stock radio, 2 or 3 threads after you set the pitch to 0, should give you like 6+ or so at mid stick.
