About this Plan

Towline Glider. Free flight glider model.

Quote: "EXCEPTIONALLY stable, this sleek little glider (shown in color on p.120) has a very flat, moderately fast glide. If it encounters a thermal or two, flights may last an astonishing time. Its best so far has been 4 min 20 sec.

After the plans have been drawn to full size, glue together the pod blank, the boom block, and the two sidefaces, aligning and locating the pieces as indicated. Use hard balsa for the boom, and medium for the pod and sidefaces.

When the glue has dried, trace the outline of the pod on the blank; then carve and sand the pod-boom assembly to shape, employing the templates shown in the drawings. Beginning 4-3/4 in from the front, taper the boom to 1/8 by 1/4 in at the tail. Mortise the wing mount into the boom flush with the V-notch in which the polydihedral wing rests. Shape the fairing block in front of the wing after the wing is in place.

The wing is built as one piece with a dihedral of 1-1/2 in at the twin ribs 1A and 4 in at the tip. The trailing edge is built up of four pieces, but 36 in lengths are used for both the leading edge and spar. Set the ribs in notches 3/32 deep in the trailing edges of both the wing and elevator. Build the rudder frame with twin horizontal braces as shown below and, with sandpaper, fair these into the leading and trailing edges. Shape both the fin and skid from 1/8 in balsa and hinge the fin with tin cemented into slits in both edges. Cover wing and tail surfaces with clear dope. Later apply pigmented dope to the entire glider.

In the first test flights, add clay to the nose until a flat glide is obtained, then adjust the fin for a circle."

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.
