Bubba, I don't have an asiatam recoil unit else this would be easier for me to troubleshoot.

Here is the basic wiring diagram for the SLU to control recoil functions. I know it works with the stock HL recoil unit and a Tamiya recoil unit (as advertised on my website). The flash unit connection is designed for a Heng Long high tension flash. If you do not want to use a HL flash unit, you can connect an LED to L3 on the SLU.



The micro switch needs to be positioned at the recoil apex (for lack of a better word), the point where the barrel is fully recoiled. Vstank recoil units will not work properly with the SLU as the micro switch is positioned inside the unit at the point where the barrel is fully extended. Hence the recoil works backwards.

Any other micro switches are not used.


Does the barrel elevation work?
