The cowl fit great length-wise and width wise. I lined the bottom of the cowl up with the bottom of the plane and the top ended up being about a 1/8 inch higher then the 4* top. I built up the upper portion with balsa from the front to the cockpit and it turned out great! I had to do a bit of rounding of the 4* fuse to get the angle right but with a little bit of trial and error it turned out great!

Cheers, Mike

PS Order at least 2 cowls, if your anything like me you'll make a mistake with the 1st one!
