About this Plan

Hot Canary. Simple all-sheet profile control line model biplane racer, for .09-.15 power. Wingspan 14-1/2in, wing area 145 sq in.

From the Article: "Hot Canary and Knight Twister" in MAN, October 1976.

Quote: "By JERRY FARR and GENE PATTY Two simple-to-build racing control-liners that will give a different look and hot performance; excellent sport models, .09-.15 power.

Biplanes are a pleasant change of pace and always attract some extra attention at the flying field. The Hot Canary and Knight Twister are easy to build, even for the novice, and are easier to fly than most trainers. Because of their size, the wind doesn't bother them, and they are more solid on the lines. These planes began as an attempt to race something different in C/L scale Racing (Goodyear). This was abandoned however, when we found out that the Knight Twister was raced at the Cleveland Air Races in the 30s and the Hot Canary raced in the late 60s at Reno in the biplane Class, not Formula One. If you intend to race these planes in competition, get an offical ruling from the AMA's CLCB first.

The advantages of a racer with two wings are not apparent without putting a ruler on them. Then we find a smaller fuselage with less side area, a shorter span with a little less wing area and less frontal area because of thinner wings than those normally used on C/L Scale Racers.

After the hassle of trying to fly in competition with 'funny looking planes' we just sport flew them and had a ball. Build them just for fun flying and use a Sport 15 or even an 09. I flew a Knight Twister with a 15 diesel, and another one was flown with a Fox 15. They were great!

Enough of this, let's build an airplane. To cut the wings, select 1/4in hard balsa and by using 4in sheet you can get both wings from one sheet, complete for the Knight Twister but you will require an additional 1in chord for the Hot Canary. A piece of trailing edge stock makes a good leading edge when glued to the wing blank. Use a razor plane to shape the airfoil into a semi-symmetrical or fully symmetrical section. Don't use a flat-bottom wing or you will have trouble holding straight and level..."

* 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.
