Solink Motor Advanced Plus Brushless Airsoft AEG Motor
(Model: 35K RPM / Long)

"Excellent, excellent motors that are not only powerful in their torque, but also get rid of the pesky Anti-Reversal Latch, making assembling especially tricky gearboxes a breeze.

Remember these couple tips when building with these motors...

1) Remove the tappet plate delayer on the Sector Gear to ensure that you can use an M120 spring and ensure you don't lose FPS when installing these bad boys.

2) Shim properly, shim well, and ensure pinion to bevel gear engagement is strong. To tight, and you will wear out gears, too loose and the pinion on the Brushless Motor will cut through bevels like they are nothing (I've seen this happen on Helical Bevels. It's insane)

3) These motors can be pretty picky about wire placement in an AEG grip, and some M4 Grips. Be careful in what grip you choose (PTS Grips seem to be fine)
4) Reinforce your gearbox (AOE correction, good Pistons) to ensure that the gearbox can deal with a Brushless Motors torque.
5) I've personally found that using this motor makes it difficult to retain the use of Maxx Hop Up units (I've had to revert to using old school VFC Hop Up units). Your mileage may vary.

I use these pretty exclusively in all my AEG's, and they are pretty bomb proof. Advanced versions are great, but don't sleep on the Lite Version either.
