About this Plan

Little Gem. Goodyear class team racer. Profile model.

Quote: "Your Two free plans! A pair of control-line Goodyear class team racers for 2.5 - 3.5 cc engines, with a proven contest performance. Designed by Dave Clarkson & John Daly.

'Little Gem'. Originally built by Jim Miller in 1949 as the Miller Special, it was subsequently re-built to its present form after a major crash. As the Miller Special (and later known as Little Gem and Ole Tiger as re-named by different owners) it has proved to be one of the fastest Goodyear midgets ever built. As Ole Tiger it has appeared with a slightly higher fin and for this reason the Little Gem plan has been selected. The basic three-view used is also from the Racing Planes Annual, increased over-scale to bring it it line with the current SMAE rules.

Construction. Two forms of wing construction are shown following the designers' personal preferences. Both feature buried leadouts and controls to give a 'clean' appearance and also to allow the unconventional 'catch' mentioned later.

The BooRay's wing is assembled using a 1/2 x 1/4 in spruce leading edge, a 1 x 1/4 in hard balsa trailing edge and medium 1/4 in sheet in between. The lead-out ways should be cut out from top to bottom before shaping the wing. The centre portion of the wood cut out should be removed and the top and bottom pieces re-installed together with the lead-out guide tubes. The wing is now shaped to a semi-symmetrical section using a razor-blade plane and sandpaper - care should be taken not to make the leading edge too sharp. After shaping, install the lead-outs and the circular bellcrank and cover the centre section with 1 mm ply, leaving suitable holes for the pivot bolt and the pushrod..."

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.
