About this Plan

Tuffy. Control line aerobatic trainer by M. Maude. Free plan with Aeromodeller December 1962.

Quote: "Looking for a control-line acrobatic trainer? This 28 inch span design fills the bill for 1 - 1.5c.c. by M. Maude. Here's a model that will really live up to its name. Flown over grass, it is virtually indestructable, especially if covered with silk. There is nothing unconventional in the structure except perhaps the means of enshrouding the engine in a neat sidewinder cowling made of plywood. This, in effect, provides a protective box around the most valuable part of your model and although there is no allowance made for accessibility, in our experience, provided the engine is securely bolted in the first place there should be no need for one to get inside the cowling. This side mounted engine arrangement will mean complete safeguard for the cylinder and if the needle valve is a long one, we suggest a protective wire hoop around it. Tuffy is specially aimed at the sports flyer and not the man who wants to fly in competitions. It will fly through most of the acrobatic manoeuvres. The novice will find it an ideal trainer for learning how to stunt and will appreciate its toughness when the odd mistake is made. Before we begin construction perhaps we should explain the 'back to front' arrangement of the bellcrank. This is because the elevator horn has been placed on the top side of the elevator as another safeguard and we also want to have the rearmost of the two lead-out wires in the wing arranged to be the 'up' line. Thus if the model tends to go loose on the fine and then fly in towards the operator, it will be the up line which will be pulled due to the fuselage yaw and the model will safely climb. We prefer to make Tuffy's wing first and we start with..."

Notes

* 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.

Scaling

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.
