+/- 12-degrees collective and 7.5 degrees cyclic is a good starting place. Any higher on the collective and your gonna be pulling mad Amperage.

Your curve should be linear (0-50-100). Adjust the range using the swash menu. Any deviation from linear is a bandaid fix for improper mechanical setup.

Depends on the radio and how many points the curve has.

take 100/curves n plug into points respectively.

This is not for idle up!!! I go w/ slight v curve on idle up!
Oh yeah! break out the pitch gauge to get your optimum setup!

+1 jolt!

I wish I still flew!!!

To add:

I like a Normal Pitch Curve starting at -4, 0 at mid stick and 12 at the top. Idle Up -12, 0, 12.

The -4 in Normal so it is a softer decent and doesn't suck sheeeit up on the ground.

Umm, changing the curve doesn't change the amount pitch required to get the thing to hover or set down gently.

V-curves are for throttle, not pitch.

The reason you set a normal mode is for beginners that tend to jam low stick when they get into trouble. Especially so for people that learned on fixed pitch or planks.

i've been flying for a good year and a half on CP Heli's. i fly pretty good Fast sport circuits..

but still the Throttle curve/pitch curve/swash mix/dual rates thing confuses the hell out me.....and i really try to read the explenations and learn.

i can dial always my GY401/9257 tail in perfect...but the cyclic and expo thing really kicks my butt

nothing to it but to do it

12 and -12 is way to high. You only need 10 to 11 at the most. I run 9 but I have fbls
