About this Plan

Tutor - Radio control trainer, for .40 to .60 power.

Quote: "What makes a good trainer? There will be as many different answers to that question as there will be modelers answering it. This is obvious when one looks over the large and varied selection of trainer designs in kits and published in magazines. A trainer is something different to each one of us. Here are my requirements for a trainer:

1. It must be a large model, so that the individual can experience take-off and landings from an unimproved field. The size will also permit the installation of the older sets still around. The installation will also he easier when the embryo pilot starts the radio fitment.

2. It must he a tail dragger to avoid the installation of nose wheel steering. A nose wheel is also very fragile and is susceptible to damage.

3. It must use a large engine (.40 to .60) to insure a reliable operation and a good idle. Most of the engine research has gone into the larger engines for the pattern boys. So why not use the best.

4. A Clark Y airfoil is a must to insure slow flight. In the beginning when the new modeler has still to develop his reflexes, he must have time to think before giving a control. A slow flyer will provide this time. It is easy to build without a jig, and its slow speed will permit a hand launch when one has to fly in the boondocks.

5. The fuselage must be a box-type construction to facilitate the manufacture of the first model. The bottom must be straight and with the box shape, it is very easy to obtain a true fuselage.

6. The tail surfaces must be solid and flat to insure an easy, warp-free construction.

7. The wings and undercan M1151 be held on with rubber bands to insure there will be a minimum of damage with those inevitable hard approaches.

8. The motor mount must be of metal and open to provide easy access to adjust the engine and to reduce vibration in the model. The mount also provides additional room for the fuel tank.

The Tutor has all of the above requirements, and when they are stirred together with a bit of TLC, a fine trainer is the reward. The model was originally designed by one of our club members, Bill MacGregor, and was built by seven different modelers all of whom had considerable success with the design. The Tutor is a rehash of this original design to beef it up near the tail and to provide a built up wing for the average modeler. It will do most maneuvers that a new modeler will be capable of doing in his first year of flying and is docile enough to last him through the year. So if you are new to this flying game, get your hands out of your poc-kets and start cutting balsa..."

* 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.
