Granville, Miller & deLackner Q.E.D. – 24in wingspan


Often referred to as the Gee Bee Q.E.D., this classic air racer was not technically a Gee Bee.  The Q.E.D. was produced by the firm GMD (Granville, Miller & deLackner) just after Granville Brothers Aircraft, Inc was shuttered.  Nonetheless, as a direct follow-on to the Gee Bee R1 and R2, the design is classic Gee Bee.

This model was designed and built in 2000 by Tom Nallen2 to compete in the Flying Aces Club Thompson Trophy mass launch events.  A durable and consistent flyer, the original model has placed in many FAC Thompson Trophy mass launch events and won a few too!  The Q.E.D. is one of the best flying “big Gee Bee” racers and this model has been successfully flown in all weather conditions.   The design features a knock-off landing gear that has protected the model from damage many times over it’s 15+ year competition career.     If you want to fly a big Gee Bee racer, the Q.E.D. is a great choice.

Qualifies to fly in the FAC Thompson Trophy Mass Launch, the FAC National Air Races, FAC Scale, and FAC Golden Age Monoplane  events.


Designed by noted Free Flight sport and scale model airplane designer Tom Nallen2, this black and white plan includes full-sized top, side and front views of all components such that they can be built directly over the plan.  Stick and sheet balsa stock dimensions are indicated on the plan and all sheet balsa parts are printed full-size for use as templates in cutting out accurate parts to construct the model framework.  This is an Intermediate-Advanced level model to build and fly and is a good follow-on to a low-wing, former and crutch-built fuselage rubber powered free flight scale, or sport model.

Model construction plan fits on a single Architectural E (36 x 48 inches)  sheet.  Plan download or print options available.
