RCTalk Racer
I was taking the cooling head off of an OFNA .26 Force engine when all the screws stripped. I used a left hand drill bit and eventually got them out. I used some old screws from my rc toolbox which seemed to be identical to replace them. However they were a bit short, but I used them anyways. Then, when I test ran it, the head came flying off and the threads of the engine block came with the screws (sliver things around the screws) and now I'm debating whether to try to use a longer screw or to just to tap and rethread the whole thing. Any suggestions?
