Quote: "Dart 2, by Mats Johansson. This construction project for a .19-size, parasol wing, R/C trainer comes to you from Sweden. The Dart 2 is an easy to fly, stable, and strong R/C model plane.
The Dart 2 is a new Swedish trainer for R/C control. It is designed for those modelers who want an airplane that is easy to fly and also is good looking. Dart 2 has been developed and improved during a period of four years. Special characteristics are that it is very easy to fly, robust, and looks like a real aircraft.
FUSELAGE CONSTRUCTION: Start with the two fuselage sides which are constructed of 3/32 balsa (the contour lines are denoted by dark arrows on the plan). Then make the 1/32 plywood reinforcement parts (white arrows). Now, glue these on each fuselage side. See to it that you make one left and one right fuselage side. After that you continue with the 1/8 x 3/8 spruce stringers which you glue into position. Note that the part of the stringer which is attached to the plywood should be edge to edge, while the part of the spruce stringer which is glued directly to the balsa surface should overlap the balsa edge by approximately 5/32 inch. Study the plan carefully when you do this. Also cut out the part of the spruce stringer where the stabilizer should be located.
Proceed with the 3/8 triangular stringers along the lower edge of the sides. Continue by making the bulkheads. Note that the firewall and bulkhead Nos.2 and 3 are of sandwich construction. Also, make the bulkheads A, B, C and D for the detachable hoods. Now, attach the firewall and bulkhead Nos.2 and 3 perpendicularly to one fuselage side. Let the glue dry and then add the other fuselage side. Join the two tail ends and check that the framework is straight. Proceed by attaching bulkheads 4, 5, 6 and 7, and the top stringer between bulkhead 3 and 4, and between 5 and 7.
While everything is drying, cut out the 1/8 plywood reinforcement for the landing gear, and glue the 1/8 x 3/8 spruce pieces into place. Then drill 1/8 inch holes for the landing gear clips through both spruce and plywood. Continue by cutting out the necessary space in the triangular stringers for the landing gear reinforcement. Then, glue this one in place. Now, mount your favorite pushrod cables and also install a tube for the antenna. Then, glue the tailwheel reinforcement of 1/16 plywood in place. Now, cover the underside of the fuse-lage with 3/32 balsa, cross-grain. After that, you attach the turtle deck of 1/16 soft balsa.
Proceed with the two detachable hoods. Please note that bulkheads C and D should have a cover piece of 1/32 plywood. The hood frame consists of two bulkheads and three pieces of 3/16 square balsa stringer. The frames are covered with 1/16 balsa. Make sure that the two hoods fit properly on the fuselage. As the rear hood will keep the cabane strut in position, it's very important that it is correctly mounted to the fuselage (see sketch for details.)
The lock device I use is the one shown in the figure. You will have to make four of these..."
Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsYou also have this plan from "modelflyvningdanmark.dk" with captions in german, and the article from MB was added there. So maybe a copy of the article can be attached here as well, where it really belongs.

Good point. Have shuffled the files around now, moved the MB article across, to sit here with the MB plan now. Thanks.

* 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.
