30+ you say...well then go for a high speed motor, some ball bearing bushings, deans connectors (provide the beter trigger response), and a lipo and youll definatly be pushing a high rof. theres tons more to increase ROF, and im sue other people will post telling you how. Also disabling the blow back is probably going to be good fro the high rof.
this is so wrong i dont even know what to say..
do not get a high speed motor .. get a magnum type, unless you want under 330 fps, the high speed will not pull anything more than a 110 spring efficiently.
Pneumatic blow back, means its ran off of air. there is a hole in the cylinder that blows the bolt back pneumatically. disabling it will do nothing for rate of fire. Maby just maby it will give you 5-10 fps
Get a magnum motor, 13:1 gears, deans plugs, metal toothed piston and a better battery.
I would also say stay away from ball bearing bushings unless you want you gun to fail on you with in like 50,000 rounds, yeah ball bearing bushings are made for speed, But they also lack reliability. I would honestly only go that route if im seeking crazy rate of fire.
Im talking 45 bbps +
Dean plugs do little to nothing for adding trigger response... thats all about motor and gears.
