ok, well, my motor is acting up.
I stated above that it failed after 15 rounds, but after exposing the motor, it started working again.
Well, was gonna break in the hopup today, but after a dozen rounds, it died again. removed the mechbox and tested the wiring. Motor seems to be the problem. Its the turbo 2000, might explain why the offical batches of AKs are released witht he turbo 3000.
