Richard Wilkens

THIS model evolved from the idea that a low aspect ratio design could be built much lighter and tougher and would turn much tighter, than one with a higher aspect ratio. With a low aspect ratio, the span is reduced, spars are no longer necessary, the weight saved more than compensating for the heavier leading and trailing edges. The large laminated and tapered LE gives ample strength where it is most needed, i.e. at the wing root while, at the same time, the tips are kept light, thus reducing the tendency for the tips to swing forward and cause structural failure on impact.

By using a straight section wing fewer ribs are needed to support and keep in shape the nylon covering. The building time for this model is therefore shortened and the design is simple yet very practical.

  Early Bird can easily be built at around 15 oz. With the large wing area of around 285 sq. in., the wing loading can be as low as 5 1/4 oz. per 100 sq. in. This low wing loading and the use of the flying tail,
