Installation and Maintenance:
•
Make certain the 3mm motor screws being used do not extend into the motor more than
0.18 in (4.5mm). Otherwise, you can internally damage the stator windings.
•
With a Sensorless motor you will need to connect the 3 ESC motor leads from the Electronic
Speed Control (ESC), one to each tab.
•
If the motor runs in the opposite direction desired, unplug any two motor wires, reverse the
location and plug back together.
•
Do not over-tighten the motor screws.
•
Brush off dirt and dust frequently from the bearings. Place a drop of oil on each bearing at
the same time.
