Circuit board A&K MK43 ?

gunnie

Hi,

I am a total newbie to airsoft, recently bought an A&K MK43 which is lacking the circuit board for adjusting the firing speed.

Does anyone of you experienced folks have a source where this can be purchased ?

thanks a lot

bring it back to the retailer and they'll repalce it, don't try to open it as this voids the warranty

It is a Circuit Board with potentiometer to adjust pulsewidth
So far I did Not find any Dealer able ( willing?) to help. (

It's a simple circuit. Can be incorporated into the existing, wiring loom.

Will draw up an example.


What you have is labelled as "OLD" in the image, a simple on/off circuit. What you want is the "NEW" circuit. The potentiometer (POT) or variable resistor is on the bottom. If you buy the right one it can be wired in.

Thought I flipped that...

Hi,
This won't work, sorry, but a Pot Never ever can handle the current drawn by the motor. Pot will be fried in a sec.
That is Why they put in a PWM Control.

Hence the if you buy the right one. They make fairly beefy ones too ya know.
You can also get a voltage regulator made too, if you access to the right stuff.
