Default RE: Tool up the Factory for this one!

A 150+ something "look see's" and so few comments? Well, I've taken it upon myself to go ahead and build a prototype from the 1947 plans, scaled up a bit. Right at 35" wingspan; fuselage is built of 1/4" X 1/8" spruce used for the upper and lower keels, side keels are 1/4" X 1/8" balsa, all stringers are 1/8" square spruce. Formers are 1/8" light ply. 4~5/16" dowels on 25mm centers for the electric motor mount (E-Flite 450 is planned power), front nose piece made of two plys of balsa cut out on the backside for the motor to turn in. The balsa nose secures to the first former (the motor will be spinning through this former) via a pair of 4-40 screws into blind nuts on the backside of the first former. Vertical fin and rudder 3/32" balsa, horizontal stab all 1/8" X 1/4" balsa. Wing uses ribs cut from 3/32" balsa, 1/4" X 1/2" spruce for main and forward spar, tip is 1/4" balsa, leading edge 1/4" X 1/2" balsa.
As of theses photos, the fuselage + tail feathers weighs in at 5 ounces. The one wing weighs all of 1 1/2 ounces.

Weigh in on the topic! Would you like to see a Globe Swift ARF?!

"Building instructions" are 8 1/2" X 11", and thats the Gee Bee 120 for scale.
