Entry level brushless motor from Solink. 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, currently no reported issues.
Speed Controller
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.
Here's some blurb from the official Solink website:
- Extended Durability: Designed with a stationary coil, the Solink brushless motor is built to last. This design significantly extends its lifespan compared to traditional brushed motors.
- Strong Torque: With its high torque capacity, the Solink brushless motor can effortlessly handle powerful springs, making it a robust and reliable choice for demanding applications
- CNC shell and D Type Pinion Gear : CNC shell can greatly help heat dissipation while D type pinion gear design is compatible with most current Airsoft brands.
The hardness rating of the pinion gear is measured at HRC35-38.
The shaft sleeve bearing specifications are as follows: outer diameter of 7.938 and an inner hole diameter of 3.175.
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.
