About this Plan

Aerostar 20. Radio control sport trainer model for .20 power and 3-4 channels. Discontinued kit from Midwest. Wingspan 52-1/2in, wing area 472 sq in.

Quote: "Before You Begin. The Aero-Star .20 is an R/C basic trainer that has been designed and engineered to offer the greatest possible assistance to someone who is both new to the hobby of building models and the sport of flying them.

This kit has been engineered to provide the greatest number of pre-cut parts, which is a great help to anyone not used to working with wood. At the same time, the total number of parts has been kept to a minimum to provide a structure that is both strong and easily built.

The importance of building this model accurately, correctly and properly cannot be over-stressed. A model that has not been built straight, correctly aligned and balanced, will not fly properly and will be difficult to control. Remember, you are only going to build the model once. Hopefully, you will fly it for a long time. So, using a little extra care and attention while building it will pay off in a model that will give you many hours of enjoyable, trouble-free flying. Follow the instructions in this manual carefully. Install and operate the engine, radio and all accessories as per the manufacturer's instructions.

When properly built, balanced and flight trimmed; the Aero-Star .20 is positively stable in the air. This means that with 75 feet of altitude, neutralizing the controls and closing the throttle, the Aero-Star .20 will recover from any attitude and assume a normal glide. This self-saving feature will be a great help while you are learning to fly.

Although it is possible to learn to fly without any help, the odds of success are slim. Unlike R/C cars or boats, airplanes operate in a three dimensional environment and their control is a little more complex. We urge you to seek the help of an experienced, competent person to assist you with the initial flights. He should be able to check your model over to be certain that it is ready to fly and he should be able to take over if you loose control during the first flights. Joining an R/C Model Airplane Club is the best way to find help. Consult your local hobby dealer for a list of the clubs in your area. We also recommend, and most clubs require, that you join the Academy of Model Aeronautics. AMA Membership will provide some insur-ance coverage, and will introduce you to a wealth of material that will help you to learn more about R/C models. The AMA can also provide you with a list of the clubs in your area..."

Some photos of an Aerostar 20 that I built [more pics 003, 004].

I was the source for the Aerostar 20 plans that Rob Reynolds helpfully scanned in for me and sent to you. I have just scanned the instruction booklet that came with that same set of plans [supplementary file]. Thought it would be a nice way to preserve one of the legendary step by step build manuals that Midwest was famous for.

Hello! Some photos of my recently finished Aerostar 20 [main pic, 007, 008]. It's fitted with a 30 Four Stroke, and some little tweaks with the cowl, which is removable. I'm pleased with it. Nice lookin kite. Happy Landins!

Hello! Two more of my Aerostar [pics 009, 010] now decorated with a registration, in fact the reg of the full size aircraft I once flew, from the South Warwickshire Flying School! Still airworthy and a fine flying machine! Build one and have some fun!

* 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.
