EPP Plank 3

This is the third plank I have ever made. Just completed, ready to fly, someday.
EPP (5mm). 2212/1400kv motor with 8 inch prop. 20amp ESC. 800mah lipo.
Control arms are bamboo spits and wire, hotglued with heat shrink wire wrap tubes.

Has single 1cm tube spar across wing and a sort of airfoil though I squished the back part of the wing flat when laminating it.

The fuselage is held onto the wing spar with a single zip tie and a few spots of hotglue. Hopefully it will break apart from the wing
in a serious crash. The wing is pretty well indestructable, being completely laminated. Very stiff and bouncy.
Should have used some ribs or lengths of foam to keep airfoil. So really is a modified airfoil with a flatplate section.
If it flies I may open up the ends and shove some foam spars in there to separate to upper and lower wing foils to get a little more
of a real airfoil. Will be interesting.

Heavy, 15.5 oz with 350sq/in wing area. Heavy because of 50grams of laminating film and 60 gram motor. WCL around 4.1 though so should be relatively floaty but with enough weight to tackle some wind.
Should be plenty of power as this motor generates 700+ grams of torque with 8x4 prop. Needed the heavier motor to balance CG. Could use 2206 motor but would have to extend fuselage or use heavier battery. I don't like counterweights.
28 in by 12.5. CG around 2in back from leading edge.
Tiny fins but I fly wings finless alot anyway.

I wanted to make a wing with as much area as possible but that can fit in a bag I have that I can carry easily on my ebike.
So it came out rectangular. I like the way planks fly too.
