Easy 100 (oz8534)
About this Plan
Easy 100. Radio control sport trainer and floatplane model, for .40 power. Wingspan 70 in, wing area 822 sq in.
Quote: "After thirty years of designing many types of aircraft, and twenty years in R/C, I decided to build myself something that I haven't done in a long, long time a basic, high wing trainer.
I gave a lot of thought to what in my eyes this type of model should be like. Good flying characteristics were, of course, the prime objective. Equally important was ease of construction. To make the model more versatile, provisions were made to have it as a taildragger, tricycle gear or float plane.
The model has a thick Clark Y airfoil, 1-1/2 in dihedral, and zero angle of attack.
The stabilizer is set at zero angle of attack as well. To make sure that the model does not climb at wide open throttle, I gave the engine 3 degrees of downthrust. This set-up has an added benefit and it is that when flying upside down, no down elevator is required to hold level flight.
Even though I was sure that the model would fly well, I was pleasantly surprised by its characteristics. With its streamlined body the model is fast when flying wide open, when throttled back, it flies and lands almost at walking speed. When stalled, it will drop the nose a little bit, then continue flying. All of the controls are very effective. The model can do all of the basic maneouvres with ease, except that it will not spin.
Inverted flight is most amazing. All of the high wing models that I have flown, with flat bottomed wiugn and dihedral, did not want to stay inverted and required constant correction. The Easy 100 is different. If trimmed correctly, it will stay on its back for a long time with no control movement needed. I guess even a simple model design can teach me something new.
The model performs very well on floats as well. As you can see on the plans, the tailwheel has a water udder extension on it, so stering is no problem. Converting the model from land plane to float plane is less than a ten minute job..."

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.
