About this Plan
Can-Stunt. Control line stunt canard pusher model. For Ohlsson .23 engine.
Quote: "For something new and different in control line flying, build this stunting canard model from the full-size plans herewith.
When the editors of Flying Models suggested the idea of a canard U-control model, we had no doubts as to whether it would fly, because of the previous successes experienced with free-flight canard designs. But, we had some misgivings about its maneuverability. This skepticism was based on the fact that the area of the stabilizing wing would have to be small when compared to the surfaces generally employed on a con-ventional stunt model.
The reason for steering clear of a large forward surface was not because we felt it was undesirable, but because it necessitated moving the center of gravity forward, the distance being dependent on the relative size of both wing surfaces and the moment arm between them.
On a free-flight model this would not be such a problem. But, in the case of a U-control model, it meant placing one or both of the control lines forward of the main supporting surface. Not only would this detract from the appearance of the model, but it also would increase the overall drag. In turn this would effect a decrease in performance, which could otherwise be gained by enclosing the control lines within the wing.
As soon as our test model was completed, we hiked out to the local flying field. We had decided that on the first flight we would proceed with extreme caution. Therefore, after the engine was tuned up for flight and the signal for the release given, the model was taxied around for approximately a half lap to feel out the controls. A slight bit of up control was then applied and the model gradually rose into the air.
After several laps of spinning around, we felt the model out with some wingovers.As we had hoped, the ship responded quickly, in spite of the small control area. Since this is a canard, the control surface is lowered when you want the nose up - to get the nose down, you raise the control surface. This is just opposite of what occurs in a conventional control-line model, so make sure you make your line connections at the wing tips accordingly. Reverse your lines so that an up movement of your wrist makes the plane climb, even though the control surface itself is lowered.
One thing that was of interest to everyone who had seen the model fly was the high speed at-tained, sometimes upward of 75 mph. For a small class 'B' profile model, this is quite a lot, indicating that the canard configura-tion can successfully be employed on other types of U-control models. Getting back to the Can-Stunt, we would like to emphasize the fact that you don't have to be a stunt expert to fly it. Proof of this is the fact..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
