About this Plan

Triumphant. Control line stunt model.

Update 18/06/2020: Added article, thanks to RFJ.

Quote: "Good stunting performance requires a clean model. Here's one for Class D and big C engines. The Triumphant, by George Lieb.

THE Triumphant was designed and built specially for stunt work. If you want a really hot ship, try it. It is simple to construct and yet is not a 'box.' When finished it's a good looking and good flying model, with what it takes to win contests. It is also very easy to fly, even for beginners in stunt.

To build the Triumphant, start with the wing, because the whole ship is built around it. Carefully cut out and sand all wing ribs. Take the 1/4 by 3/4 trailing edge, taper it, then sand it carefully. Pin down the 1/8 by 3/4 bottom spar with 1/16 shims under it. Glue all ribs in place. The top spar and the trailing edge are added and glued well, after which the gussets are cut out and cemented in position. Glue the leading edge in place.

When the wing is dry, the controls are put in place. Cut out the maple bellcrank support and drill the hole for the bellcrank. Glue this in place and when dry, bolt the 3 VECO bellcrank onto it. Put the .029 lead-in wires through the wing, and bind and solder them next to the bellcrank. Add the 1/16 wire push rod, bending the end at a right angle about 3/16 from the end. Put it through the bellcrank and solder a washer in place to hold it on.

The wing is now sheeted with 1/16 sheeting. After the sheeting is well cemented, the tips are made. These are carved from very soft blocks. The outside, or right wing tip, is partially hollowed and about 11/2 ounces of clay or putty is put inside. This tip is then glued in place. The inside, or left wing tip, is hollowed, and drilled for the 1/8 brass tubing which is cemented in. After this wing tip is glued on, and the cement has, dried, the whole wing is well sanded.

The fuselage is built right on the wing. First cut out the 1/8 plywood side brace pieces. Cut out the maple motor bearers and cement them to the side pieces with a good grade of hardwood glue. I use Weldwood glue for this..."

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.
