Was wondering after pulling the uper part out of one of those little 15 dollar 1/24 scale tanks (the hit lights,power light,and the little mirror reflector that receives the signal from the opossing tank).Re-installed this back into a semi-scratch built upper hull,and don't know how any of the other's work for sure.But the one I re-installed still works after putting it in the other hull.Very easy to do----
