About this Plan

Mr Mulligan. Free flight scale power model.

First published in Popular Mechanix, January 1937, this here is a faithfully redrawn enlargement (the draghtsman unknown) of the plan, scaled up to full size and now on a single sheet. See article for magazine drawings unscaled, as first published.

Quote: "Model gas-driven Plane is speedy flier. Mr Mulligan, by Joe Ott.

Here's an exact scale model of a famous racing monoplane, Mister Mulligan, winner of the Bendy Trophy and the Thompson Trophy races at the 1935 National Air Races. Recently the original speed plane set a new record in flying from Chicago Airport to Floyd Bennett Field on Long Island in 2 hours, 45 minutes.

The model is scaled down to a wingspread of 66 in, and is driven by a tiny single-cylinder gasoline motor swinging a 15-in propeller at 3,000 rpm. Under good flying conditions the model will attain a speed of approximately 18 mph. The total weight of the model ship ready to fly is 3% lbs, or 56 ounces.

Part I - Fuselage Framework and Landing Gear.

ALTHOUGH it was a great thrill to fly your first rubber-band model plane, it's nothing compared to the realism of flying a gas-driven model! Midget gasoline motors that develop from 1/8 to 1/5 hp will fly readily a 5 to 8-ft, plane weighing up to 5 lbs. The average cost of the motor is about $15.00 and all the materials needed to build the model of Mister Mulligan cost around $3.00.

Before proceeding with any of the details, it's a good idea to become familiar with the entire general construction of the model. When the actual construction is started, go thoroughly and completely in detail over the particular unit being assembled. Then lay out in single lines a full-size drawing of the fuselage, landing gear and tail wheel as in Fig.1.

Fuselage: Looking at Figs. 2, 3, 4, and 8, begin with the center line which is the bottom longeron and which is the main longitudinal member in the body. One body height is given in the cross sections at station 5. This height continues through stations 6 and 7. From here through to station 12 there is a gradual taper above the center line. The top longeron tapers... "

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
