The Zenmuse gimbal package include rubber = mounts for the gimbal base. Balancing the props or changing to carbon = fiber props is just not necessary.

 

One last caveat:  the Zenmuse gimbal = corrects for pitch and roll (hence the =932D=94), but not for yaw. You = still have to fly the craft very carefully to compensate for yaw (left/right) movements.
