First, LOVE the look of this mod... wouldnt dream of ever going back to factory cannon.
However, now every 25-50 plays, the cannon loosens and rotates just enough for the "tail" of the cannon toy to catch the slingshot plastic and hangs the cannon assemble from rotating.
I believe they eventually changed the design, but I have an earlier model where its connected with a single screw .
I've tried purple loktite on the screw, but it seems to eventually work its way loose. I hesitate to use anything stronger....
Any other Hemi cannon users find a solution to this issue?
