I really wanted to have a Giant Flapjack at FF last year, and hoped to have one this year, but ran out of time. This is the next best thing.
I plan for this plane to be primarily constructed from PETG, but the option is there to use carbon fiber impregnated filaments. Even the stuff that doesn't take to glue well. If I can print this thing with something light enough, it should be possible to sand it up, then fiberglass it and still come out okish on wing loading.
Some quick specs:
Wingspan (body): 33.45 in 850 mm
Wingspan (Tailerons: 46.46 in 1180 mm
Wing Area: 992 sq. in. 64 dm2
Estimated Print Weight: 2.7kg (Very Early Estimate, hopefully I can get this down some)
Estimated AUW: 4.8kg
Wing loading: 24.6 oz. / sq. ft. 75 g / dm2
WCL: 9.2
The AUW includes some 3520-6 720kv motors, and two 4500mah 4s batteries, servos, carbon fiber, ESC's, landing gear, wire, and some buffer. The wing loading is actually a bit better than the Northern Pike.
I'm working on this thing as fast as I can. Hopefully I'll be able to take one with me to Flite Fest in Ohio in a couple weeks. We'll see how fast I can finish things up. Progress is decent, all of this stuff is printed, or printing. Just got to finish the landing gear, and the lightening holes for the rest of the plane.
