Re: Building the fuselage

I agree. Fit everything you can without the sides. There is much that you need to access on the inside that is way easier to do without the sides in the way. Delay gluing them on as long as you can stand it.

Re: Materials to build my elevator

. . . What ArthurD said. In any glue joint, the nails' only purpose is to serve as a clamp while the glue dries/sets. After that, the strength of the joint is carried by the glue/gusset.

Re: Rib cuts

Re: Corvair Campers with wood props

Oscar, I have not flown mine yet, so take this for what it is worth. I have carved my prop according to Dan Helsper's 'power tool' instructions. Before I did any carving, I calculated the 'ideal' prop according to standard prop design equations. With input for 100HP (Corvair), 3150RPM, and 90MPH the...
