Simple Duster. Radio control sport model.
Quote: "As long as we have schoolyards to fly from, .049 powered models will be popular. This is Fred's third model in his Simple Series based on the Cox TD .049 engine and the Ace RC mini foam wings.
The Simple Duster is a simple scale model of the Cessna Agwagon crop duster. Crop dusters can be seen anywhere in the country spraying fertilizers and other chemicals on our nation's farmlands. To watch a duster flying low over a field, then zoom up into a graceful pirouette and return for another pass is always a thrill. The skill of the duster pilots is amazing - dodging trees and ducking under power lines or popping up over them. The turns and maneuvering makes their precision, low level passes seem simple. Whenever I am out driving and see a crop duster working a field, I pull over and watch. It is as good as any airshow.
Like the other models in this series, the Simple Cub (oz6426) and Simple Citabria (oz7278), the Simple Duster is as simple to build as can be. Construction time is only a few hours, ready to cover. The Simple Duster uses the Ace RC tapered, mini-foam wing, landing gear, wheels, spinner, and motor mount, A complete hardware package, #37E30 is available from Ace R/C that includes the landing gear, wheels, motor mount, spinner, fuel tank, horns, hinges, nuts and bolts, and other necessary hardware to complete the model at a very special low price, $7.50. The tapered or constant chord mini-foam wings are sold separately. The airplane can be built from five sheets of 3/32" x 3" x 36" balsa, one piece of 3/32" plywood, and one piece of 1/16" x 36" music wire, one roll of covering and some trim. The entire airplane, less engine and radio, can be built for less than twenty-five dollars.
All of the Simple Series airplanes are spirited, two channel performers. The finished models weigh about eighteen ounces ready to fly and, with a TD .049 or .051 engine for power, they are quick and agile. While the little Simple Scale models are not streamlined as the 1/2A pylon racers, they are the same size and weight and use the same power. Yes, they are fast. The Simple Duster will loop and roll easily just like you would expect, but it will also fly inverted and do instant snap rolls. The full power spins are spectacular and recovery is instantaneous. It sometimes takes longer for polit to recover than the modelel. What is fun is to do low level passes over the runway just like the real thing, then zoom up into a hammerhead and come back the other way. The Simple Duster is an unusual model, as you don't see many low winged models controlled by only rudder and elevator. The full scale Agwagon has a lot of dihedral and so does the model. This much dihedral is necessary for the model to make smooth rolling turns using only the rudder..."

* 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.
