About this Plan

Construction notes:
1. This is a very light model. All wood should be light but stringy if sizes specified by the designer are used. 1/8 sq longerons and 1/16 x 1/8 crossmembers would be less flimsy with minimal added weight. The low-pitch prop and 8-strand motor should be adequate if airframe weight is held to about 4 oz.
2. Build a fuselage top crutch directly on the top view, curves drawn are not critical. Let the longerons assume natural shapes within reason and symmetry cut and cement the side pieces for the four formers on the sections drawn when the crutch has set up, remove pins holding the forward section and block up at the front 5/8 in. Cement the four key formers in place, making sure they are vertical. When set, cement on the lower longeron. Carefully cut and mount the remaining uprights fill-in the nose and rear reg bays sheeting.
3. No dethermalizer was used on the original model. 1/16 sh cut 2 in wide to form a platform for the stab with conventional hooks would be suitable. Crossmembers or bracing at the stab leading edge will be needed to prevent crushing the rear longerons with the hold-down bands.
4. 3 degrees incidence specified. A 3/32 x 1/8 strip cemented at the lower spar exactly gives that angle strap on the wing with rubber strip and slide fore or aft for best glide.
5. Bamboo tips were used for the prototype three moulded laminations of 1/32 x 3/32 for the tail and four for wing tips would be a suitable alternate. "
