After dusting off some 30 year old engines to do some C/L flying again, I found one of my Fox 15s (angle plug head) has a stripped glow plug hole. This engine was always a good runner and I would like to repair if and use it again if for nothing but nostalgic reasons. The actual Fox # is 11502. I have searched around and can't seem to locate one. I guess I have been out of it for too long. Learning that many Fox and Cox engines were no longer available has me feeling like the guy at the end of Planet of The Apes!!! I do have some old planes in good condition that I plan to fly again soon, like a Ringmaster Jr. with a pristine Fox 25 bushing, A Combat Cat with an OS 35S, a Lil' Satan with a Cox 049, and a Flite Streak with a Fox 35. I am looking for a Jr Nobler too. If anyone could steer me in the right direction I would surely appreciate it!!!
