About this Plan

Thermal Thumber. Free flight power model.

The Thermal Thumber (oz6207) was first published in 1941 MAN. This here is a later redrawn plan from MB.

Quote: "Old Timer Model of the Month. Thermal Thumber, by Maurice Bryceland. Redrawn by Phil Bernhardt. Text by Bill Northrop.

The May 1941 issue of MAN featured a construction article on this Class A gas model, the 'Thermal Thumber,' designed by Maurice Bryceland. Prior to publication, numerous copies had been built and flown by modelers in the metropolitan area of northern New Jersey, New York City, and Long Island.

On November 17, 1940, Thermal Thumbers took 1st, 2nd, and 3rd at the annual 'Frost Bite' Gas Model Contest, sponsored by the Vineland (NJ) Aeronauts, at Bucks Flying Field, Woodruff, New Jersey. The second place, in Class B, was taken by one Walt Schroder, a member of the Strato-Bums, of Bloomfield, New Jersey.

The plans, as published in MAN, gave no indication of the 'V' cross-section of the aft fuselage, but the accompanying photos included a framework shot which gave the proper shape. Our plans, as drawn by Phil Bernhardt, correctly show this.

Thermal Thumber is excellent for modern Old Timer pylon class competition. It has lines very similar to the popular Cleveland Playboy (oz7835), and the construction surely qualifies to be described by that popular time-worn expression: straightforward."
