High Noon (oz9356)

About this Plan

High Noon. A2 Towline glider model.

Quote: "THIS model, High Noon, is the outcome of a development of A/2 gliders since the class gained international popularity in 1949. A high aspect ratio wing with 25 percent tailplane was used to achieve a reliably low sinking speed, the tailplane being mounted high out of the wing wash to give it maximum effectiveness with a normal length fuselage. Ample side area gives the model trouble free towline staility in a wind.

Apart from minor changes to construction and aerofoil section the flying surfaces have remained unchanged from those on the original model. The wire bracing struts and the attachment of wing to fuselage provide great strength on the towline as well as being reasonably crash-proof when trees or buildings obstruct the model's approach.

The fuselage has been progressively streamlined and improved in detail and the present structure is surprisingly rigid for its weight - curving the 1/16 sheet sides results in greater stiffness than with flat 3/32 in. Structural weight at 12 oz gives ample strength and with ballast at the CG makes for stability by reducing inertia effects.

Fuselage. Bind the towhook and wing strut hook securely to the 1/4 x 1/8 balsa bottom beams. Fix the auto-rudder lever to the port side of the ply top keel. Cement formers F5 to F8 to the towhook beams and cement the ply keel in the top..."
