About this Plan
Troika. Radio control sport biplane model for .50 4-stroke power.
Quote: "Let Mike Conrad tempt you with his 47 inch triplane. Troika.
I think that the most annoying part of producing a new design is thinking of a name for it. One puts so much effort into the design and construction of a new model that just giving it any old name really isn't good enough.
The name Troika, which means a combined effort from three different sources, emerged after sounding out club members, family and other disinterested parties, as the only suitable name which had sufficient class and came off the tongue easily.
Now, why build a sports Triplane; haven't I got enough troubles? Well, this is my 90th radio model, so it had to be something special. I've built and flown biplanes of all shapes and sizes so a tripe it had to be.
The trouble is that when one thinks of constructing a three winged model, one feels it might be silly not to go the whole hog and build a Fokker or a Sopwith. Well, I have not got the patience for the fine detail required of a scale model, and I also wanted to start with a clean sheet without the constraints of having to make it resemble a known shape.
The other factor which would put me off a scale Tripe is the difficulty of making it easy to assemble on the flying field. This is important to me, as when I get to our patch I like to fly, not spend hours putting models together.
Concise construction: This is a model which could be built by anyone who has a couple of biplanes under his belt, but it is not a beginner's model.
It will be seen from the plan that the wirework allows for fore and aft, and up and down movement of the centre wing. Bend the elongated U pieces to shape and bind piece 'A' to the cabane uprights loosely enough to allow up and down movement. Bind piece 'B', which plugs into the wing, to piece 'A', again loosely enough to allow fore and aft movement.
After building the top and bottom wings, attach them to the fuz and make up the struts. Run the completed struts through the centre wing as shown, and attach clothes pegs to the strut..."

* 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.
