Trigger master problem

[joker060]

First let me list what has been done to my gun.

-TM MC51
-Guarder sp110 spring
-Metal bushing spring guide
-Metal bushings
-Shimmed
-KA light weight piston
-Elementz silent piston/cylinder head set
-Systema tightbore
-9.6v 1400mah battery
-Trigger Master MosFet chip

I installed the trigger master last night and have had only one problem. It seems like my gear timing keeps getting messed up resulting in the spring being fully compressed and unable to fire. I tried redoing it many times but have come to the same problem. I am thinking that I need to slow the motor down some to compensate. If anyone can help it is greatly appreciated.

Well DonP or Terry (Gandalf on Airsoftmechanics.com) would be the ones to ask...

But, so far as I understand it from using Terry's SW-AB-Long, the active braking still does it's thing but doesn't have the same effect on full auto as it does in semi. In semi, it does seem to stop the piston very close to fully forward (i.e. so the spring is at its most uncompressed state), but on full auto it will stop the piston as soon as it can whenever you release the trigger. In full auto the piston can be anywhere in it's cycle when you release the trigger. I've observed this personally testing it.

In sounds like your battery/motor/spring combo is not balanced. Even without a MOSFET, you should have your stuff setup so that the battery/motor should be strong enough to pull the piston even when starting from a fully compressed state.

What motor are you using?
Did that spring/motor/battery work fine (all the time) before?

With the Computer version of this MOSFET, slowing down the motor may help, but theoretically the piston could still stop near/at full spring compression on full auto.

I hope that helps, but probably doesn't. Take it with a grain of salt, I haven't played around with adjusting motor speed to see what +ve/-ve effects it might have.

The gun had no problems before. I am using the TM EG1000 motor. Thanks for the help though. I slowed the motor speed down and so far no more problems.

*EDIT* - Took the gun out to a game and had the same problem again.... anyone able to help me out?

With this setup what would you recommend for a motor?
