My scale plans listed below are available for free download......
Many of my plans were designed from the full scale ship and/or full scale blue prints purchased. Some were purchased from the Vintage Sailplane Association, VSA. I was the BUNGEE CORD's (news-letter of the VSA) editor for several years. Other blue prints were bought from the builder/designer, ie. Jim Marske - Monarch C
The plans listed below "freely downloadable" were designed in the 70's and 80's. I will redesign them in 1/3 scale, untilizing modern airfoils, Quabeck and Selig/Donavan and modern composites. Proto-types were built in the 70's and 80's, flown and corrections/adjustments were made to the plans.
NOT FOR SELLERS WHO WISH TO COPY AND RESELL TO UNSUBPECTING CUSTOMERS!!!!!!!
NO NEED TO BUY FROM <UNCLEWILLIES>
The originals are 20 -30 years old. They (most) were drawn on vellum and have been subjected to many temperature changes. The originals have been through many, many old fashion blue print and blueline machnes - (Ammonia vapors, etc) through each generation of copying machines to the modern machine. Even the mylar originals can become distorted.
Please lay out all parts, dry fit, and adjust for perfect alignment and shapes.
Also, use a Quabeck or Selig Donovan airfoil, thicken to 14-15% ie. SD3021 -- instead of the flat bottom airfoils on the downloaded drawings.
There are several free on-line airfoil application.
More plans will be added as soon as they are ready...
