short stroke m249

[generalbaxter]

i want to short stroke my m249

at the moment its putting out a crappy 15rps at 300fps on a 9.6v battery
im after 330fps with around 20-25rps
all stock aparts from
CA piston,
CA vented piston head,
CA cylinder head,
custom nossle,
shimmed
AOE

would you recon a m120 with 3 teath nocked out would do the job ?
i really hate trial and error lol,

please note, i dont do lipo lol

Just an m100 would be fine at only 25 rps .

Re: short stroke m249

yes but with the teeth cut off it wont do 330fps, lol

i dont even know what motor is in it, cant it be replaced with a high speed one
?

I'd say something else isn't as it should be in there. On a good 9.6v should be easily into 20+.

What are the battery specs?

I had an MP5 running at 23/sec with no internals mods except G&P M120 motor with 9.6v 4800mah battery!

Talk to midas he knows his stuff but
m100
shs piston short stroked by 3 teeth
g&p m120 or element max speed
and wired to deans

that should be able to hit 25 rps

Have to disagree there, even with modify modular speed gear set and 9.6v batt it was about 20 rps in my M4, it's the M120 making the big difference. It jumps to about 29rps with it...
