Just a few hours ago i installed this motor into my G&G Blowback MP5A4.
The motor is very well packaged, insulated in a plasic case with foam padding.
Installation is very basic, slipped into place with no problem.
I plugged in my 9.6v 3600 Mah and let 'er rip!
The rate of fire is absolutley ridiculous!
It ripped an amazing ~22 Rps!!
Thats an extreme improvement over the ~13 Rps the stock crappy G&G motor put out.
However, once installed you may need to re adjust your motor height.
Decently power efficent
May need to re-adjust motor hieght after installation.
