About this Plan

Fire Wagon. Free flight power contest model.

Quote: "The margin lies in one's ability to get the most out of the machine he's flying. The 1/2A Fire Wagon incorporates certain design features which insure excellent performance provided the builder follows the-building instructions, trims the airplane properly, and avoids downdrafts.

The Fire Wagon falls within the small hot category. Its wing area is just under 250sq in projected. With a hot 049 or 051 engine, it's a potent contest machine. With an 049 salvaged from a plastic model, it's just right for sport flying.

One important feature is its ease of construction. This airplane was designed on the theory that a model does not have to be complicated and difficult to build to be an excellent performer.

Design features include an aft rudder for climb stability under high power. Most of the rudder is actually below the thrust line, which puts the vertical fin in the right side blast of the prop, giving the model a right power turn. This arrangement plays an important part in the transition. The left adjustments (stab tilt and washout in the left wing tip) cause the model to turn left in the glide. The prop wash overpowers the left tendency, producing a right power climb. When the engine stops, the left-turn forces take over, causing the plane to turn sharply to the left. This results in a smooth transition without loss in altitude.

Whether an expert or beginner, the modeler will enjoy building and flying the Fire Wagon. It's as simple as it looks and it flies as easily as it goes together. Select only-lightweight contest balsa if the airplane is to be used for contest flying..."

* 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.
