About this Plan

Hot Canary. Control line speed model. For Dyna jet power.

Quote: "Hot Canary, by Herb Davis. Top honors at the Nationals! First place at Plymouth! National jet speed record job with 157.43 miles per hour! This Dyna-Jet powered speedster flew at 150 on its first test hop!

The Hot Canary is a hot, fast ship. It is painted yellow, built small and light. The total weight with Dyna-Jet engine comes to a modest 20 ounces. The fuel tank is a result of trying many types. It will get you off under most weather conditions and provide the required laps for the clocking. The tank is made by hollowing out nose to 1/2 in thickness on all sides. First the nose is split open and then hollowed out. The inside of the tank is coated with 4 coats of clear dope or until all pores are filled.

Drill holes for tubing and glue in front vent. For fuel line heat a piece of 1/8 ID thin wall brass tubing red hot; let it cool and then bend it to shape and glue it in the tank. Fasten tank halves together with plenty of glue.

The wing is 1/8 ribs covered with 1/16 planking and a 1/8 beech spar. Cut out bottom planking to outline on plans, glue ribs in place. Cut spar and lay across ribs, mark and cut slots in ribs for spar to be glued in. Bellcrank is installed with pushrod and lead-outs. Put on top covering.

Install wing. Cut 3/16 x 1/2 x 3-1/2 notches in the fuselage for wing and notch for spar. Bolt spar to fuselage with 4-40 bolt. Groove for pushrod. When gluing wing make sure no glue gets near top of body, because glue tends to burn from the heat of the engine, causing undesirable results.

Stab airfoil is symmetrical and should be mounted at 0 degrees incidence, with wing and engine. The rear fairing should be bent on a 'brake' for a perfect fit at a sheet metal works. Front fairing can be cut from pattern and sent to shape. Rear saddle and front yoke can be put on after fairing parts are installed. Asbestos paper from back of front yoke to front of rear saddle is held with water glass.

All metal fittings are removed before painting. The wings are covered with tissue, Glue a 1/2 in strip of gauze to bottom for a skid. Top of fuselage is covered with masking tape. Apply four coats of a mixture of equal parts of talcum powder and clear dope, sanding between each coat. Apply three coats of yellow dope, rubbing last coat with rubbing compound, then wax.

The model is skidded off the ground instead of a dolly take-off. White gasoline is used for fuel with a No.4 metering jet."

* 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.
