Hi all,

I'm running a 3D Pro with the Century Outrunner 13t pinion and a CC25 controller. Initially I was runing the controller in high RPM governor mode with the throttle set at 93% but I have verified that the tail wags a lot while the controller tries to keep the RPM constant. So I decided to try the fixed throttle mode and when I finished the throttle curve to fit my desired RPM I have verified that when the battery voltage drops the RPM drops too, until I hover at max pitch. The good thing is that the tail stops wagging. Now I'm in trouble. What setup do I have to use? Keep the governor mode and accept the tail wag or go to the fixed throttle and accept the RPM decay? Both are bad for 3D flight. What setup do you use on your 3D Pro?

Any suggestions will be very welcome!!!

Thank you and Regards,

Marco Paulo

i'm not flying 3d yet. but, i use a fixed rpm (or a v-curve actually---100-88-100).

it sounds like you are just flying the pack too long. max pitch for hover sounds like you're awfully close to the lipo cutoff anyway.

if it ain't broke…break it.

I'm running a Thunder Power 3s 1320mah'but I'm suspecting that the performance of the battery is not 100% now...
