gots to start reading somewhere...

AoE (angle of engagement) correction and shimming are probably the most important factors to a reliable gearbox whether it's shooting 12rps on an 8.4v battery or 50rps on a dsg monster. Smoother turning gears create less resistance and allow the gun to function more efficiently.

If you don't want to mess with lipos since they require a bit more attention to upkeep, a 9.6v L battery build for p90s will be better than your 8.4. They cost around 30-40 bucks. That and a wiring upgrade are probably the first things you should try to help your issue, but you need to slow down your trigger pulls and make sure you pull completely rather than halfway. It's really the only safe bet to not encounter the semi lock issue.

My gun fires in a matter of milliseconds, I can still lock the gearbox with really fast semi auto trigger pulls or if I try really hard. I can pull the trigger faster than the gearbox can cycle, even at 30rps so you'll never eliminate the problem completely.

this is what 30rps sounds like My m4

- YouTube I don't have video of my p90, nor do I currently have my team chrono to show and measure exactly.

note the trigger response on semi. This guy used a different combo of parts to achieve this number than I did. Not to mention running a hotter spring. Even with a trigger pull that fast, I have locked up my p90 a few times in one game, so it doesn't really matter what you do to your gun, it WILL lock up if you don't let the mechanics finish doing their work before letting the trigger go or pulling again. Shoot, full cycle, shoot again.

It's a problem with AEGs that you have to live with. A new high power motor like an SHS high torque or lonex A1 will do it for you, but the lonex is closer to 60$ while the SHS is maybe 40. While I have not tried G&P motors, I can't justify spending the same amount on an older ferrous magnet motor rather than a newer higher power neodymium magnet motor. Look at the price of the guarder extreme torque up motor vs lonex A1... 85 vs 60$ and the lonex can pull a much stronger spring with more power efficiency at a higher rpm. More torque, more speed, less money.

Also, for all intents and purposes, most 7.4v lipos will perform similarly to a 9.6 but in a smaller package. Not exact, but similar. Power delivery is completely different. I ran my p90 before all the upgrades on a 9.6v nimh at about 16-17rps on stock gears.
