"Well I purchased this gearbox well over a year ago as is. I have completely built a gun around it with a price tag of about $600, and this gearbox and body are still running strong. The wiring myth is true it does get hot, but nothing will happen to the gearbox from my experience. I have a Lonex Hopup, Angel Custom 6.01 TBB, Angel Custom H-Nub, and G&P bucking installed and my gun shoots 415-425 FPS with .20 at about 17 rps, with a 7.4v 20C 1000mAh LiPo.

Sturdy body
Perfect fit threads for any rails
Rails on top are perfect
Sick trades
405-410 FPS out of box
Long Wire
Solid feel

The heating up wiring(not an issue)
Big ass Evike logo on the right side (personal, just don't like it)
The part where the buffer tube goes onto was a bit too long and I had to cut some off to get my buffer tube on.

"Seriously I'm not even sure if this is a real G&P... no G&P markings ANYWHERE (not the mechbox, externals, nothing...). Even the exterior threads for the RIS should different from other brands and well... it's not the case. I opened it up with my tech and even he thinks there is something weird about it. Personnaly I think it's an evike knock-off from China but that just my assumption. Oh forgot to say my gearbox cracked in my first season....

"I purchased this on hopes of a quick remedy to find a metal Reciever decent gearbox. From what I have seen from G&P beforehand was quite promising. Upon testing this out with a 7.4 LiPo battery, I noticed the motor, battery and wires getting hot. Mind you this is about 30 shots on semi. While I expected heat, I didn't expect this magnitude. I open the motor trip to find a G&P M120 motor which I expected, but didn't expect te to. Connections to the screw terminals on the motor to be so loose. There was at least 1mm of play which makes for horrible resistance. After cranking the screws down. Still heat but not as much. Hoping to reshim, correct AOE. All the realizable basics.

Metal Reciever & decent gearbox

370-380 with .25s too hot for indoor. (Could be pro)
Poor Assembly from Factory
Not worth price
