Matrix High Performance Airsoft AEG Motor (Type: Sonic - Super Speed / Short)

"It's a strong motor and runs cool in my setup. However the pinion gear failed in less than 3 games, and took my bevel gear out with it.

For reference: M130 18:1 recoil shock aeg (piston also pushes a spring/weight in addition to the main spring.)

"Good motor and very fast with a powerful magnet.
Uar dose not not like this motor very much, would recommend a different gear set if used with this because I re-shimmed my gearbox to fit this perfectly and it had shredded out inside after going to full auto.

Upon inspection the Uar pinion gears are different than regular pinion gears.

All motors are not always a drop in or great solution to stock setups.
