Re: Cleanflight aka Multiwii port to STM32 F10x and F30x
... I've got two Flip32+ units here, one of which I'll be puting into the quad and it seems the latest Flip32+ board I received from Paul doesn't include the second accelermeter (Freescale MMA8452). It includes just the single Invensense MPU6050 like the Naze32 includes. I was curious, if choosing ...

Too much vibration hitting the acc is one reason for that. The mwii IMU part is also part of the problem but holding the copter still in the air for a short time should correct the internal horizon. If only landing is able to correct that your setup has too much vibrations coming through to the acc...
