Set Up for Low Maintenance Hi ROF!
There has been a lot of discussions regarding Hi ROF, I have ventured to the extreme and have found out that the most playable low maintenace hi ROF set up is between 25-30 ROF, >30 be ready to spend a lot.......hehehehehehehe!

Set Up for 350FPS without too much modification
1. Minimum 7mm bearing GB
2. SP90 spring
3. piston head with bearing
4. shaved 2nd/3rd tooth of PB (swiss chess it if you want)
5. Spring guide with bearing
6. stock gears/hi speed gears.
7. hi speed motor (we prefer M120)
8. Power source of your choice (I normally use 9.6v 3300-3600 NiMh/ 11.1 lipoly 12C-15C.

You can easily attain this, measured using audio analysis!
27 spikes/sec. = 27bb's per second

I wish this could help!

Good post. I just fixed my high speed setup... lasted all of 2 minutes at my last game. :( Fired the gun a few times... gun jammed up and shredded the piston (and broke some teeth of the sector gear). I opened it up, and noticed I had put the sector clip on backwards... though I dont know if that would cause the gun jam?

Shredded piston body on a HiROF set up is always a direct result from improper AOE and combination of improper gear aligment which will result in a cathastropic mechbox failure. Buddy! try to invest so much time on shimmimg and aligning your gears. And there are available parts that will help you set a perfect AOE.

AOE was adjusted perfectly (or so i thought?)... Used lightweight washer/shims inbetween the piston/piston head. 2nd tooth, and part of the 3rd were removed... sector engaged the piston as flat as I could get it.
