Windfreak model airplane plan


RCModeller's Windfreak

Northern California's Roger Sanders designed the 100" Windfreak, undoubtedly one of the most eye-catching and attractive flying wings ever! The model was featured on the cover of RCM magazine's November 1978 issue, flying over (I believe) Los Banos Reservoir, and was designed to be a high performance glider flown from winch launches or on the slopes. Note the careful attention paid to low drag with the thin wing airfoil and minimal volume streamlined fuselage. The original design, as shown on the plans, featured elliptical 'tip dihedral' transitioning into the wing's flat center section; wing assembly can be readily simplified by 'straight line' tip dihedral rather than the elliptical which requires creating a custom wing jig to properly warp the spars, leading edge, and trailing edges to that curvature. This editor and his son had the pleasure of flying a Windfreak for several seasons on the US East Coast in the mid 1980s and remember those flying sessions with great pleasure - the Windfreak is a wonderful design that flies as good as it looks!

About the Plans Printing Service.

About the plan source:

You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling. To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.

Plans Scaling:

We can scale the Windfreak plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.
To order a scaled plan please copy the plan url or ID and send us a message with the desired wingspan an any other info you may find useful.
