A nice view of our slowest, lightest, glider, gliding free.
The
sheet is cut and layed out. Note the left wing must be turned upside
down. Since the wingtips from a plan with 27.5"X2 wingspan scaling go
off the Depron sheet, the two triangles of excess material will be
taped on the tips to augment the elevator surface area.
Next
Lines are drawn on the undersides of each wing and a slight bend is
thermoformed along each line to create the airfoil. I added extra lines
midpoint between dimensions J, I&J and I&H to make a smoother
curvature.
Here
bends are thermoformed to create the elevator surfaces. Once again, I
inserted an extra set of lines mid point between the K dimensions for a
smoother curvature to the elevator. Note the wingtip pieces are
thermoformed at the same time as the wing. Then taped in place
