Hello All,

I am currently turning my cyma m14 ebr into a DMR with around 530 fps that is permanently semi-auto. Currently I am running at 530 but the last thing holding me back is trigger response. The motor that originally came with the CYMA is struggling to pull the M140 spring and it is heating up a lot in the process. On my other DMR build this was easily fixed with a new motor, it also on a side note improved trigger response dramatically. The problem I am having is that the motor type on the CYMA M14 EBR is different than on their regular M14s and appears to be a mix between and long and short type motor. The motor axle itself protrudes the length of a long type motor, but also has these plastic spacers on it. The tension spring on the other hand is short and wide like the spring on the short motor.

Getting to the point, I would like to know if anyone has had any experience replacing the motor on an M14 EBR by CYMA, and what type of motor did you end of using, and what modifications did you make to it.

*I will add pictures shortly*

Thanks,
