About this Plan

Tora II. Radio control sport model. Wingspan 2950 mm. For 38 cc motor.

Quote (google-translated from the German): "Building Instructions: Tora II. The construction of the Tora II begins with the fuselage, where we need sheet 1 and sheet 2 of the construction plan, which consists of a total of 3 sheets. Before beginning, connect the side view of the fuselage drawing at the dividing line so that the last fuselage web 2 on sheet 1 and the first fuselage web 2 on sheet 2 have a distance of exactly 171 mm from each other. Also note the distance between the other webs Page 2. That the course of the longitudinal belt 1 on the upper side of the fuselage must form an absolute straight line is self-evident.

Now attach the assembled drawing so that it lies absolutely flat on a correspondingly large construction board. Here's a little tip: place a transparent foil over the drawing so that the parts don't stick to the drawing but to the foil, which can then be easily removed again.

The torso straps 1 have a length of 1.7 m, and in order to achieve this length, individual sections must be neatly shanked together, with the shank being 10 to 15 times the length of the material thickness. With the 8 mm x 8 mm last used here, this corresponds to a shaft length of 8 to 12 cm! When both longitudinal straps 1 are fastened as shown in the drawing, insert the fuselage webs 2 and the diagonal strips 3 and attach the reinforcements 4 and the corner reinforcements 5. Caution: When installing reinforcement 4, make sure that there is a 5 mm gap in the area where frames 14, 15 and 16 are drawn, into which these frames can later be inserted.

The second fuselage side panel is manufactured in the same way, paying particular attention to the fact that the gaps here are identical to the fuselage side panel built first. After completing this work, place both parts on top of each other, sand clean and level. As a check, we now put a 5 mm strip of plywood through the superimposed side parts of the fuselage at those points where frames 14, 15 and 16 will later be. There must be no distortion between the two side parts of the fuselage. Make any corrections now.

Now prepare the planking 6 (0.8 or 1 mm plywood), cut out the recesses (according to sheet 2) and use them to planke both sides of the fuselage. Make sure to create a right and left side! (Plywood outside.)

Before proceeding, cut out the openings for the spar bridges. For this purpose, the exact location of the opening is either taken from the drawing by tracing or transferred to the component with the help of the drawing dimensions. In the end, it is important that the straight bottom of the profile has an angle of 1° relative to the upper longitudinal chord. This gives the required wing EWD of 3.5°', measured along the profit chord. Also, the openings for the spar bridges should not be cut out to the final size, but kept a little smaller. The openings are only adjusted to the exact size after the spar bridges have been completed..."

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.
