I just picked one of these up yesterday. The instructions suck! The first line under Installing the COW says to line the cowl up with the marks you previously made on the fuselage. Just to make sure I didn't miss a step, I went back and reread all the instructions. No where does it have you make marks on the fuselage! The dihedral brace was about 1/2" too small width-wise for the openings on the wing. And the instructions say to pour epoxy in the wing opening after coating the dihedral brace [:@]. Why would anyone in their right mind do something like this? Too much epoxy is just extra weight! And, it is impossible to get the engine mounted for the space from the firewall to the thrust plate without replacing the mount. As I have already fit the cowl, I think the manual is wrong about the distance. Mine is around 4-1/4" and everything looks good.

Anyway, last night I epoxied the wings together, mounted the engine (OS 46AX), and mounted the cowl. I replaced the fuel tank, as it is a 3 line tank, and I do not have anything laying around to plug the fill line. I ended up using another tank that I had laying around with a Sullivan fuel filler valve mounted in the cowl. Tonight I have to extend the needle valve so I can adjust it with the cowl on. One thing that concerns me is airflow input to the cowl. There seems to be ample space for the air to exit the cowl, but to get in, right now I only have the holes cut for the head and muffler, along with about 1/2" or less clearance around the spinner backplate.
