The Flying Wing: A Scratch Design / Build

A 29mm Powered Flying Wing utilizing a Rear Eject Spool

2026-10-11 Nose Cone

Turned the Nose Cone on my wood lathe from Pine, I glued a couple pieces of 2 X 4 together to make this.

Also cut the templates for the Wings

2026-10-12 Wings and Tubes

Cut, Sanded and routed the wings... Cut the BT/C-70 Tubes

2026-10-13 C-70 and Wings

Laid out and prepped the C-70 for the fins.

Poked (70) 0.044 diameter holes through the C-70 for each fin.

Then injected glue through those holes, wiped the excess glue from the coupler,

and then glued the wings in place.

Wing Fillet Dowels

2026-10-14 Through Wall Gluing

Poked (120) 0.044 diameter holes through the C-70 tubes, adjacent to the 3/16" dia dowels. Then injected Gorilla Wood Glue through the holes, incorporated into the fillets.

Titebond Quick and Thick Glue Fillets

I noticed the C-70 tube was oval, due to the shrinking of the tube due to the glue drying.

I installed the fixture I built that's used to make a C-60 tube oval, basically two wooden ramps. I used these to force the tube back into a round condition while the glue dries. The Nose Cone was insert also to use as a rounding fixture.

2026-10-15 Sanding C-70 i.d. and installing the BT-70H

Used my home made Bore Sander to smooth out the through the wall glue "rivets".

Cut the BT-70H, applied Gorilla Wood Glue onto the outside of the C-70 and Elmer's Glue -All White Glue to the snout of the C-70, and then slid it into place.

After letting the glue set-up for a couple hours I started gluing the BT-70H to the Wing Dowels. The BT-70H was sanded at the glue joints.

2026-10-16 Nose Cone Ballast and Dowel

Cut the Steel Ballast, 1" Dia. x 1/2" Long, and the 1" Dia Pine Dowel. Then used Gorilla Wood Glue to secure everything.

Tube Fins

Cut the BT/C60 Tube Fins using my Chop Saw. Scuffed the Tube Fins at the attachment locations using Sandpaper, then applied Gorilla Wood Glue to the Wings and placed the Tube Fins.
