Okay, I'm considering getting a warp feed for the ol' Angel, but I see these interface thingies on several sites. Waht the heel are those for? Forgive me for asking a dumb question perhaps, but I'm a technofobe.......
It is similar to the intellifeed mod, it will make the warp spin a set amount every time you pull the trigger (determined by warp dwell setting). It is useful if you have trouble setting up the vibration sensor on an angel.
I have not seen it connected to that, all the interfaces i have seen for the angel have been done to the wiring in the grip frame and then this runs out and plugs into the bottom of the warp feed.
check out www.airgun.com they have an extensive guide to doing this for an angel lcd.
