||Two days into this gun, started as a 3 star, but with a little work it is a 5 star. It came with a small 8.4 volt NiMh, not enough to turn the motor much. I put in a 9.6 NiMh, works but unable to fully use it's features. Also a 7.4V LiPo kept the ROF low. This disappointed me at 1st, but I built a 12V NiMh, and it came alive. The MOSFET started working well and the ROF was very good. I had to clean the gear box a bit, but not much. I also found chips on the paint, painted over (overspray found on the gear box).
Extremely durable, heavy, and accurate build
Easy to maintain.
Easy to upgrade.
Adjustable MOSFET really works!
Ammo box can fit large batteries
Ammo box auto feed also works well
Cosmetics aren't the best
Needs a bit of work before getting it's full potential
Ammo box auto feed switch is backwards (continuous on auto, auto on continuous)
Overall, I love it. compare the next vendor's cost for this model is $2K, this is absolutely worth it. This might work better with a high speed motor, I believe it is a high torque installed, hence the slower rate of fire with lower voltage batteries, but don't quote me.
