Knotty Girl Sport Goodyear

Bill Bischoff

Presenting the Knotty Girl, a design for Sportsman Goodyear. I want to begin by thanking Doug Mayer for his fine work in converting my pencil drawings and hodgepodge of notes into a complete set of plans. Doug shares my affinity for Goodyear, and has several free plans and outlines available as well.

The full-scale Knotty Girl first appeared in 2009, and has undergone a host of cosmetic and aerodynamic changes over the years. The plans depict the plane as it flew in the 2014 season. The basic fuselage "bones" are from a Cassutt, and the wing is from the well known "Li'l Quickie". I'm not sure if the color scheme deliberately borrows from the GMC van on the A-Team TV show, or if it is just a coincidence.

Structurally, the plane is built just like the Margaret June, featured in the June 2015 issue of Model Aviation. By the way, do you realize that there is more to the article than appears in the print magazine? If you haven't seen it, please look it up on The construction article is quite comprehensive, and even two years later I don't know that I have anything new to add.

Again, big thanks to Doug Mayer. As they say on the A-Team, "I love it when a plan comes together."

O.k., here are the plans.
