MultiWii

Hello again.
I'm trying to build my Bicopter a long time now and finally seems that i ' m too close at the moment.
But ... I'm facing a problem that i can't understand.
When LEVEL MODE activated the two motors not spinning with the same speed, and when deactivated both spinning as expected.
Any idea why ?

acc trim or have you got one cw and one ccw prop

yes....bicopter use one cw and one ccw props

Then its got to be acc trim. Even though you calibrate the acc you are only telling it what is level. What the acc doesnt know is the, friction on motor bearings, variations in material densities, etc that's what acc trim take into account.
