About this Plan

Tri-Yi. Unconventional rubber sport model.

Quote: "Tell the beginners in your club to try 'TRI-YI!' This weird-looking little rubber-powered plane has plenty to recommend it besides novelty. The unusual three-in-a-row wing arrangement lends exceptional fore-and-aft stability and the counter-rotational props allow powering it up as much as the fuselage and your nerves can stand. It will flash along at terrific 'scale' speeds in level flight, or climb nearly vertical out of sight if you use a winder on the motor. Incidentally, the prop construction method is a dilly for strength, accurate pitch and easy going-together. We bet you'll soon be using props of this laminated-twist construction in preference to carved blocks/blanks on rubber jobs."

* 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.
