Airborne media scale detail, that sounds nice... they offer some pretty extensive detailed info; stuff you could only get if you had access to the real aircraft... for the right scale project its worth the investment... I was thinking a Moki radial, but they maybe too big; I think the smallest displacement is a 5cyl 180cc... or a 5 & 7 cyl 250cc, and then a monster 5cyl 400cc... the evolution 9cyl is 99cc... nice looking engines... now you got me all excited...your heart will be just fine, if you take care of yourself, and stay away from those PB magazines.
Oh, hand making that cowl would be something to watch.. I enjoy doing stuff like that, and use to have the dexterity to do it, but its not so easy now with these old hands... but that cowl is a piece of artwork... there's not many left that can do that kinda hand metal work... no more apprenticeships to hand down the skills.
