Title: Tighter Roll
Post by: funtimegrandpa on June 03, 2016, 02:51:14 pm
Hello,  I am using the Eachine 250 modified with Little Bee ESC's and a Revolution.    Things are working well but I wanted to know if there is a way to make tighter Rolls?  I dont understand some of the settings and figured I should ask before tinkering.   Any help would be very much appreciated. 

Thanks again,    Grandpa jake

Higher rate mode response and max rate limit. The higher the degree per second rotation the faster it flips or rolls. I'm flying with about 550*/second. Which seems plenty fast for now. I started with around 450-480 and it's fast but not fast enough. The mid 500 range seems about perfect

The rate slider. The middle one at the top. Change it from 450 to say 500. Then try 550 if that's not fast enough.

Or ,  are you flying in attitude mode grandpa jake ?

Like NicolasDavid says in first post, be sure the rate value you set is not limited by the Max Rate Limit value.

My current rates on my 3s "X" copter are 550 pitch and roll rate and 600 max rate limit. 70 expo on roll and pitch 20 on yaw at 400*
