Hubsan Q4 Nano yaw issue

[Reigate_Heli]

Happy Christmas all..

Just looking for some troubleshooting advice please.

So this tiny quad has a pitch and roll trim but no yaw trim (rudder effect)

In the hover having trimmed pitch and roll to keep it as steady as possible it slowly yaws (laterally) to the right and frustratingly there is no trim setting for this. I have to input some left rudder (yaw) to compensate..

I have checked for consistency in the rotor blades and for debris around the motor spindles..

Nothing doing so far

Any help appreciated!

Thanks

Fixed it - one of the motors had rotated in its housing by about 30 degrees - moved it back - working perfectly now

Ive one the same and noticed it did the same yesterday after a crash landing and it was the same issue the plastic motor housing had moved in its holder following the bang and allowed ghe motor to pitch to one side slightly - easy fix tho well spotted
