Just now, with one simple change, I corrected a long standing (months) problem with vibrations and motor power surges/chattering. What was that "one simple change"?...I switched my CC 35 (with version 1.55 installed) from governor mode to fixed throttle mode!

In governor, the vibes were shaking the verticle fin 1/2 to 1 inch wide (at the bottom end), and vibes were easily visible in the skids--as if the the main shaft is slightly bent. Plus, the motor (Neu 1107/2Y) was power surging in a jittering-chattering-chirping (annoying!) way that made the tail twitch. I reprogrammed the ESC from governor to fixed throttle and BAM!--no vibes at all, and a perfectly smooth motor!

So why is this so "Unbelievable" to me? Because I have been flying for 3 years ONLY in governor mode! With my Mega, I never had a problem with gov--it worked great! But with the Neu (that I installed a few months ago when upgrading to 4S), these vibes and power surges had me thinking the motor bearings were bad. But no more--I'm a believer in manual throttle now! Now I just need to get my manual throttle curves right for how I fly.

So, anybody have a recommendation for 3D manual throttle curve?

Wow to think you would have experienced nothing but pleasure with the Kontronik Jazz escs governor, it works flawless, the problem you relay is specific to CC escs. Glad you did figure out what works for you with that esc though. Since the 450 heli is so small, not much mass and the motors well can only have so much tourqe you can run a flat fixed curve or if you feel need you can run a very shallow v curve, from center to outward make your difference only 10 points max throughout idle 1 and idle 2. Most even in fixed run a flat curve.

...Once upon a time there were Nitros, flybars and frequency pins...

Thanks, OICU812, for the curve recommendation. And rcheli-freak21, gov gain?...Never even occurred to me! I'll stay with manual for now, then maybe tinker with gov gain to see what works best. Thanks to both of you!
