				Crazyflie 2.0: Lots of trimming needed

				With my crazyflie I need a roll trim value of 4.5. Is there something I can do about it?

				Hi, to me it sounds like it could be a vibration issue. I think you balanced the propellers (from another thread)? Does it make a lot of "vibration" sound when flying? When you take off does it go strait up or start tilting directly?
In the new cfclient there is a config screen where you can set trim values permanently. This will compensate for e.g. a tilted MPU9250 chip. You get to the menu by first connecting to the CF2 then under Crazyflie->Configure 2.0 you'll find the paramters. We are still lacking documentation for this but we are working on it.
