Entry level brushless motor from Solink.  The latest batch (May 2025) have the updated controller that increases torque 10-15% with the same RPM, enabling them to drive heavier loads more efficiently. In addition they have enhanced start-up performance, ensuring quicker response and overall a greater reliability during usage.

The external shell is CNC machined from aluminium.  Uses a D Type pinion gear with a hardness rating of HRC35-38.
The motor tower OD is 7.9 and an inner hole diameter of 3.2

These motors have great heat efficiency, reliability and performance from either 7.4v or 11.1v.  According to Solink you can use AB and Precock, and state their motors are fully compatible with all ETU's.

Speed Controller Tip
Whilst the LITE edition doesn't have an external speed (20% reduction) switch, you can access this by removing the 4 screws on end cap and using a pin switch the selector (see photo).

Statistics with 11.1v:
AT NO LOAD
SPEED =27800 RPM
CURRENT =1.6A 

AT MAXIMUM EFFICIENCY
EFFICIENCY=72.9%
SPEED =24747 RPM
TORQUE =398G.CM
CURRENT=12.4A
OUTPUT = 101 WATTS 

AT MAXIMUM OUTPUT
EFFICIENCY=45.7 %
SPEED = 13960 RPM
TORQUE = 1810G.CM
CURRENT = 48.5A
OUTPUT = 248 WATTS

IMPORTANT
1. Do not power the motor with the cables reversed.  Always check this.
2. Solink state that this is the most ETU compatible motor on the market and can be used with AB should you need to, so far no reports of any issues.
3. As with all motors if you get a gearbox lock-up, don't keep your finger on the trigger trigger.  Use common sense.
4. If changing the pinion yourself do not force it on, do not whack with a hammer! Too much force will damage the rear bearing or controller.  There's some good guides on YT on how to remove pinion gears on brushless motors.
