About this Plan

T-34A Mentor - Scale model for control line. For .45 to .60 power. McCoy 60 shown.

Quote: "This clean looking military trainer was one of the most successful in aviation history. Developed from the extremely popular record breaking Bonanza commercial design the Mentor was selected as the standard trainer for the United States Air Force. A close copy was procured by the United States Navy and designated T-34A. Orders for this popular craft came in from Chile, Columbia and El Salvador while arrangements were made to manufacture the plane, under license, in Canada and Japan.

The T -34A was selected as the standard trainer of the US after a ten year debate regarding the characteristics required for a trainer in this jet age. Primary, Basic, Advanced, and Acrobatic training as well as Cross Country Navigation and Instrument Flight instruction could be accomplished with the Mentor. It was also used for Tactical Training when equipped with machine guns and rockets or bombs.

The T-34A is extremely maneuverable and has an ultimate load factor of 9-G which allows unlimited stunting with complete safety. Rate of climb is 1,182 feet per minute; during take off the Mentor clears the ground in about 1000 feet and can clear a 50 foot obstacle in 1500 feet. During landing the ground roll is about 400 feet.

This rugged trainer is very easy to fly while maintaining its maneuverability. Furthermore it has that big plane feeling which is important in trainers, making the Mentor ideally suited for its task.

The plans illustrate a man size control line beauty suitable for any engine; glow plug or ignition, from .45 to .60 cubic inch displacement. The scale of 1-1/ 2 inches to the foot gives this model a wingspan of 49 inches and a projected wing area of almost 400 square inches. A model of this size is ideal for a super scale project so plans and photographs include hard to obtain cockpit details. Navigation and landing lights as well as an illuminated instrument panel are easily installed in this spacious model.

Construction begins with the wing. Cut spars, landing gear supports, ribs and joiners to shape, assemble spars with plywood joiners. Note that one pair of joiners are slotted to receive the landing gear supports. These are cemented in place, followed by the wing ribs..."

Hello from a former rebellious colony, How difficult would it be to add retractable landing gear and construct as an electric powered radio control? Thank you!

Hello again, In general, can plans for a given size, i.e. 21 inch wingspan, be modified to different dimensions? Say enlarged to a wingspan of 38 inches? Would additional re-engineering be required? Could the existing plans be photographically shrunken or enlarged without inducing structural weakness or adverse handling? Thank you again!

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.
