    Hi all, just changed over to deans, amazing the difference using stock 8.4 1600 mah, but there in lies the problem, on semi auto it snaps the bb's out really tight trigger response, full auto is seriously fast but the motor seems to wind on after releasing the trigger and it does not feed consistently ( I will install a sector clip for this) by the way it's a V3 in an AK 105 DBoys cyma not to sure of brand. Don't want to waste a MOSFET in this so any ideas would be greatly received
    Btw Deans connectors an extremely cheap and effective upgrade!!

    is your anti reversal latch fitted correctly first off?
    motor continuing on suggests trigger contacts are not separating properly... check the spring in the trigger components too...

    If you dont want to use a mosfet:
    Retard the timing(angle of engagement) That is set the nub of the sector gear back to about 2'clock (instead of the usual 1 0'clock).
    Use a higher torque motor.

    As FK suggested check the trigger return spring(one connected to male end of trigger contacts. You can check its funtioning manually with box open,also be sure its not rubbing off tappet plate.

    Do use sector clip for feeding issue.

    turning the selector gear is a myth.

    Teeth are in the same place, as is the pin that actuates the tappet pin. Its just going to take longer to reach the piston, fracitonally. the tappet is cycled at a precice point in the cycle, and both are fixed together.

    I was talking about the SECTOR gear :). Seriously though each to their own opinion-just sharing mine:)

    sector... selector.... Funny, I always heard it as selector... i just googled sector and realised how bloody wrong I was all this time! rofl

    Opinion or not... im afraid the timing is fixed, unless someone has made one with a movable peg... because its in the same position relative to the toothed 'sector' Moving the gear on its axis will have no effect as the pickup occurs at the same point.

    Im not bashing your opinion Minder, Im just explaining that the timing is fixed, and the actual engineering working behind it... Opinion has nothing to do with it.
