About this Plan

Silver Schtick Bostonian. Rubber free flight model.

Direct submission to Outerzone.

There are pics and video of maciej's completed model online here: http://awiatikforum.ok1.pl/viewtopic.php?t=356

Quote: "It was a couple of years ago that two very compelling factors brought this delightful little project to fruition:One, the then-forthcoming 12th Annual Fourth of July Bostonian Fun-Fly, hosted by Walt Mooney in San Diego, California, for which a new airplane was needed; and two, the long-standing desire to execute a rubber free flight version of Phil Krafts ubiquitous and super-successful Das Ugly Stick (oz5175), possibly the most popular all-around RC aircraft ever.

A short telephone conversa-tion with Phil yielded an admission that he had designed the Ugly Stik in 1966, so more fuel went on the fire - also the 'Silver' nametag for the design's 25th anniversary.

Within a five-day period, two prototypes were scratched together, but not test flown. One was almost entirely made from 3/32 square and sheet stock, the other a 'light' copy of 1/16 balsa throughout. On contest day, each survived the maiden flight. Both were a tad heavy in the nose. For the record, Bob Langdon's 'fat' version had the best time at over 4-1/2 minutes, so what the drawing reflects is a viable distillation of the pair: Larger stock sizes that help out the fumble-fingered among us, and a shorter nose. On a good day, the ship can easily do two minutes with a little themal help, so beware, this Schtick is for real!

Experienced Bostonian West warriors may wish to do the whole thing in 1/16 square, change the airfoil, or even eschew the open cockpit/windscreen for a closed cabin. Wheels and props can be obtained from several sources, and the color schemes can vary all over the place. Make sure the wood at hand is both strong, straight and not too heavy. One half ounce is the target. Every gram above that figure will rob seconds off duration, so keep light weight in mind at all times.

The fuselage ends up a squat little box, but starts out as two identical sides built over the plan, then separated with a razor blade before the addition of cross-pieces. Lay down a row of pins top and bottom to locate the longerons. 'Crack' the sticks with a thumbnail to accommodate the sharp angles. Cut and fit the nose sheeting and motor peg holder. Cut all the uprights carefully and test-fit them in place. Put a dab of Titebond on each and all, then set aside again and let dry five minutes orso. Re-dab each gluing surface, and install all the pieces. Let dry overnight.

In the interim, other things can be done, like roughing out the wing and stabilizer outlines, cutting ribs, or laying up the rudder outline, , which is three strips of 1/32 x 3/32 balsa, soaked until wet, then taped around a circular form. Or lay pins on the inside rudder outline and laminate the strips directly over the plan, as l did. Use white glue or Titebond; CA glue sometimes bubbles on wet wood. Let it dry properly and sand well before putting in the rest of the structure.

To complete the fuselage, sand all surfaces, then carefully slice the two sides apart with a single-edge razor blade. Flat sand the inside surfaces, then 'crack' in the angles shown on the top view. Cut the crosspieces that form the widest part ofthe fuselage and trim them to identical length..."

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.
