Re: Re: F1D box question

Mike,

A good reference for a model box design is an article written by bernard hunt in indoor news and views issue #103. This can be downloaded from the existing news and views web site. I use foam with cut slits to mount props and fuse. For wings you make an open channel formed from a 1/8 sheet base, two 3/32 spaces rails, with two 3/32 lips glued to the rails. Then make a 3/32 base with a finger tab made from a balsa block, and two balsa blocks with 1/16 dia. holes drilled to push your wing posts into. The balsa base holding the wing then just slides into the channel. The balsa channel can be glued to the back wall of your model box. I glue a balsa base to the end of the channel and a support gusset for strength. Good luck with your box and will see you at EAA.

Two of these side by side, load a wing, add spacer, load wing, add spacer, rinse, lather, repeat. At the top, another 1/2" piece slides down onto the music wire with just enough clearance for the box.
