Budget level brushless motor from Solink. This version is primarily sold only to the Chinese domestic and some SE Asian markets. Essentially it's almost identical to the LITE version from what I can see, differing only in the end-cap design. The controller is identical. The official performance stats differ slightly with the torque and output power roughly 10% lower. Real-world perfomance wise, in my test AEG I didn't notice any difference.
Like the LITE the external shell is CNC machined from aluminium and uses a D Type pinion gear with a hardness rating of HRC35-38. 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. Personally I prefer to not use AB on the ETU.
Speed Controller Tip
Whilst this version 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).
Video is in Thai but you can set the auto-translate function in the settings.
Motor Grip Modification:
Some (very few) motor grips do require a small amount of adjustment to the end plate of the grip to get the best fitment. This seems to affect all brushless motors.
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, no reported issues currently, however I recommend avoiding setting your ETU AB just in case).
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.
