Hey, hey, hey, I just reread your post and what is this I read RCS150 You lucky dog, whoooooo, wow, I'm jealous. That is too dog gone kool. The sound coming from that cowl should be truly impressive. Whooooo, I'm excited for ya. I thought I had a good birthday (that got me the gear, etc.) boy, do send a photo or two with that puppy inside the Avenger cowl. You lucky man. One day I'll get a round engine. I'm going to use your idea of the 1/4 x20 nylon bolt instead of the metal bolts. Chic
