NBM1c - 2m Flying Wing

Foam Cores

Hotwire cut with Gravity Feed Hotwire Cutter

Preparing Cores

after Cutting, the Cores get glued together, I cut the Spar slot, glue in the Sparcaps, cut out the Elevons and Flaps, and face them, also reinforce the Leading Edge to form an Overlap between Top and Bottom Wing Skin

I prepared Mylars with release agent and painted them, I also cut all the cloth needed, skin and reinforcements, the cloth gets layed up on the mylar, and the Foamcore gets sandwiched between the two Mylars inside a Vacuumbag and cured for >16hours at ~45deg C


for the Drivetrain, it took me 3 tries to get a good solution, it's a homemade Shaft with prop mount as one piece and a moulded Carbon part that I screw the motor to and press-fit a support-bearing into.

Finished Wing

it flies very nice and I am satisfied with the result, few things to improve but its a prototype...
