Further Description/Back Story

Mark Ward’s model of the Gee Bee R3-M came about by envisaging where the Gee Bee Aircraft company racing plane development may have progressed to if the company did not go bankrupt when it did. The R3-M could have been developed with the larger and more powerful Pratt and Whitney Hornet engine (later installed in the R6) keeping the front-end style of the R1 and R2 airplanes. The elongated fuselage provides better stability and overall performance in line with the fantasy R3 model that has been around for some time. This modified version R3-M is a pure racing airplane with a large powerful engine, sleek airframe, and consequently fast performance.
Please enjoy the 25% scale model which is based on existing full scale racing airplanes and some lateral imagination!
