About this Plan

Colt 35. Radio control sport model, by Alan Schwemmer from November 1967 AAM.

Quote: "Contest-proved Class I winner which doubles as a docile Sunday flyer. A sport or beginner ship when its .35 mill is throttled down. Colt 35, by Alan Schwemmer.

The Colt was designed to give good all-around performance on a .35 engine. The original model has fulfilled my needs quite well. It placed second in its first contest before the dope was hardly dry, and has a continuous string of first places since then, including the last two West Coast championships.

But the real joy is to throttle back slightly and just spend the day flying it around. When not on high power the model is quite docile and can be used to shoot touch-and-goes one after the other. A deft touch on the throttle will make others think you are flying Class 2, the throttle substituting for an elevator.

Fuselage: The construction used gives a very strong, yet light-weight airframe capable of taking a lot of punishment; is straightforward so general practices may be used. Start with the fuselage sides as the left-over 1/16 sheet is used for wing and stab ribs. Butt glue together three 1/16 x 3 x 48 in sheets. Both sides can be cut out of this sheet with a minimum of waste. The firewall, bulkheads, and 1/2 in blocks should be as square as possible as they determine the alignment of the sides.

Laminate 1/32 ply to sides from nose to bulkhead #2. Add 3/16 square stringers and 1/8 x 3/8 diagonal bracing. Laminate 1/32 ply and 1/2 in balsa stab-mount doublers. Glue on 1/2 in tank compartment side blocks and hardwood motor bearers. Drill holes in firewall for nose gear mounts. Pin one side to a flat surface and glue in firewall, bulkheads #1 and #2..."

* 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.
