piece 'o cake
6 ribs, 2 carbon tube spars, 2 carbon tube leading edges, ply motor mount and some balsa sheeting. Not much to it. It will take you longer to cover than to frame up. Jett 50 will make it greased lightning. I used hitec 5945 servos. A cowl may make it cleaner but heavier. The DD has alot of drag to begin with because of the spacing of the ribs causes the covering to sag alot. The airframe makes alot of noise when flying and when you cut the power, the DD slows down quickly. I have been considering making one with leading edge sheeting and balsa half ribs. Any thoughts out there? Good luck with yours.
