About this Plan

Toucan. Radio control aerobatic sport model for (2x) .09 - .10 engines.

Quote: "IF, LIKE ME, you have always fancied a twin-engined model but have been put off by frightening tales of what happens when one engine stops then please read on.

Toucan offers an average sport flyer the chance to reliably fly a twin engined model with none of the worry about what to do if one of the engines stops. So much so, that to the surprise of my fellow club members. I regularly take off on just one engine in complete safety.

When both engines are running a transformation occurs and the model becomes very aerobatic and fairly fast and the unmistakable sound of two engines beating together is guaranteed to turn heads wherever it is flown.

The plan shows nacelles to suit 0.10 - 0.15 cu in motors which are quite adequate for the model. You could, I think, squeeze in a pair of 0.20 sized motors but provision for larger fuel tanks would be necessary.

Wing: The wing is basically a one piece unit with no dihedral and is best built the right way up on the plan. Commence building by pinning down the 3/16 square balsa main spar and 3/16 square spruce auxiliary spar to the plan. Now add the ribs, followed by the 1/4 x 5/8 leading edge section and then the square trailing edge support. Before you sheet the top surface with 1/16 balsa don't forget to add the ply webs on both the main and auxiliary spars as they are very important and have a significant bearing on the final strength of the wing.

Remove the structure from the board and add the motor speed torque rod assembly which is simply glued into small slots cut in the under-surface of the ribs. Now sheet the bottom of the wing with 1/16 sheet and add the soft balsa block tips followed by the trailing edge aileron torque rod assembly which is glued to the centre of the wing. Finally carve and sand the wing to the section shown on the plan and add the 3/16 dimeter dowels..."

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.
