Indoor Endurance Tractor (oz7288)
About this Plan
Indoor Endurance Tractor. Freeflight, tractor monoplane, rubber power. Span: 19in. Author: Merrill Hamburg, A.M.L.A. Publisher: Houghton Mifflin Company. Manufacturer: Akit was sold by the A.M.L.A. which cost 75 cents, postpaid.
Year: 1928, original publication 1927. Plan Size: 8.5inx 11in. Source: MerrillHamburg, Beginning to Fly, 1928, page 101. Originally published in American Boy, December 1927. Scale: 1/6.13, digital file. Notes: Scanned and edited in PC Paint. I added name and year to the title block. The 19in span is 3.10in on the digital file, thus the scale ratio of 6.13. The size in a print will depend on settings in the printer software. The original book drawing was 3.38in x 4.70in. Enlarging to print full size would not be practical; build on a pencil drawing. Note detail differences between this and the one published by Garber. This motor stick does not taper to the ends. Motor is a 15in loop of 1/32in x 1/8in rubber. This plane was reported to fly for two to three and a half minutes. It twice won the Indoor National title and held the 1927 world record.

* 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.
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.
