I vote for cutting it. It looks like it'll fit the contour of the turtle deck fine. All that platic forward of the cockpit loos strange... (unless you open out the fuse to make room for two seats maybe?
And scale or no scale, I love the look of that cowl. It does make it look like they swapped the usual Lycoming HO-540 in the Edge with a PT-6
(Maybe you should add some faux elephant ear exhuasts to complete the transition?)
Also love that perfect 1/8th inch cooling ring. I'll have to try this built up balsa cowl technique sometime... it looks like a blast
Nothin' better than standing knee deep in balsa shavings IMHO.
