The aimtrak is a Bullshit, I have one instaled in an Original Namco gun, it works fine but you have to be a mast, if you move from the place where you calibrated it is unbalanced, and better not speak of the kit of aimtrak recoil, other shit, the best thing that I recommend is to buy only the pcb and install it inside an old Namco playstation gun or the other alternative, wait for this new gun to come out. Ultimarc has become very rich selling the aimtrak light gun , because its manufacture does not exceed 25 dollars. The big problem is that the geeks don't repair spending even if we are hungry, we only care about satisfying our whims and no matter the price. I hope this new creator does not abuse like him.
