GW Xieda 9958 motor for WL Toys V911
A modification I highly recommend is replacing the motor of a V911 with a motor of a Xieda 9958
. The Xieda motor has one more tooth in its pinion gear than the V911. The tightness between the pinion gear and main motor gear produces a quieter V911. The Xieda motor's slightly larger diameter will allow the motor to sit higher in the V911's frame, which is necessary because the pinion gear sits lower on the shaft. No spacers are needed. The motor holder
has to be left out but it isn't necessary.
