Yea, I relize with a stronger spring you need a stronger motor. The rate of fire is fine. Its the speed of the piston moving forward to propel the BB out of the barrel. The motor should not effect speed of the piston when released to fire.
Thanks for the tip.
Nope sorry buddy your wrong..... You need a higher voltage battery. A "Stronger" motor is not going to do anything if you dont have enough juice to push it over....
That's exactly what Justin, my brother did to his M4a1. He got the upgrade and the motor. Now, he needed to pay extra for the battery, which doesn't last more than 4 games, so he needs to 1. pay extra AGAIN to get the stock motor 2. Or get another battery.
Just like SAD to say upgrade the motor as well, "you need it".. now we know better!
