Taigen MFU and Asiatam Recoil Unit

[MichaelC]

Hi all,

Been trying to put in a Asiatam recoil unit into a Taigen MkIV and is having a hell of a time. The Asiatam recoil is famous for the lack of instructions but this is my fourth one so I figure I know what I am doing by now. For some strange reason the recoil I have is even different than all the other ones that have been discussed here. First of all the microswitch is not located on the top of the unit behind the elevation mechanism, but is inside the recoil gear. Secondly, the big thick wire which is suppose to goto the battery negative directly is hooked up to one of the contact on the microswitch which I didn't think was the case. I have done the blue/white connection to eliminate the switch, and then there is the yellow/green/red which is suppose to goto the small patch board I believe which in turns goes to PIN 3/4/5 on CN9.

When I have everything hook up I get recoil and elevation, but not sound/flash/track. Didn't make much sense so I figure, if that's the only things I am missing, I can stick in a diode mode (i.e. diode pin 5 instead of PIN 4 on CN3 to pin 4 on CN9) and bob is your uncle. Well, I got everything to go, but there is a second firing sound. Upon close inspection, it almost looks like the microswitch is somehow set wrong, and when it goes back to reset position it actually trigger's another firing sound, although there should have been associated track recoil and flash but there clearly wasn't.

I guess my question are, has anyone try fitting asiatam recoil into an Taigen MFU ? I know even the diode mode is slightly different for Taigen vs RX-18, and I am worry the pins are slightly different for the gun and elevation connections as well. Secondly, I though sound/flash/track recoil are all trigger by the same signal. Is it possible to just have firing sound without the others ?

Don't think the Taigen mfu board has a sound/flash/track on it.I've just got mine and there's no gun sound or track recoil when the airsoft unit is fired.
Also found out from Tankbear on this site that the Clark/Elmod boards aren't a straight swop with the mfu units as no separate reciver unit.
Edit : Also on mine there are wires and a plug from the airsoft microswitch that doesn't fit anywhere on the mfu board
