You're right lurkingknight, this motor can pull m150 springs and above with no issues. I only gamed this motor once (using m120 spring), went to the game on Waterdown scrap yard. Did a lot of semi-shooting because of feeding problems on full auto. I had tested the motor before I put it in the gun, I noticed that it did get a bit hot but thought it was normal. I spoke to Stealth from airsoftstore.ca and he also mentioned the brushes might be worn out, so we'll replace the brushes. I just want to get to the root cause of the problem, this motors are not cheap and I don't want it to die on me. I also tried using numchuck 9.6v batteries and get the same problem.
