About this Plan

Jetwing. Simple all-sheet model for Jetex 100 power.

Quote: "Build this 19 inch span flying wing for the Jetex 100. All parts full size. Jetwing, by Bill Dean.

THE smallest Jetex propulsion unit - the 100 - is ideal for all sheet models of the chuck glider variety. We have based the Jetwing design on experience gained with sheet flying wing gliders. All up weight of the model presented here is slightly less than 2 ounces.

An average speed builder should not take more than three or four hours to get this model ready for its first test flight. Construction is simple - providing you follow the correct building sequence. All parts are given full size, so trace or pin prick them on to the appropriate thickness sheet. The one-third scale drawing on the opposite page gives assembly details.

Begin by cutting out all the parts. Two laminations of 3/16 sheet - instead of the 3/8 sheet - may be substituted for the fuselage (1). Two pieces (5 and 6) will have to be joined for the main wing panels because of the width.

WING: Pin 5 flat on the plan, then cement (and pin down) 6 and 7 to it. When dry, remove from the plan and shape to the indicated sections. Use a sharp razor blade to trim away most of the surplus wood, then finish off with fine sandpaper. Note than the wings do not taper in thickness towards the tips.

Build the opposite wing panel in the same way. Now place the central edges of the wing panels on the edge of the building board and sand them to a slight angle for the dihedral. Pin one panel to the building board and prop up the other 3-1/4 in at the tip, then cement together. Now cut away the tips (7) and re-cement them in place at the angle shown. Pin each panel flat on the board in turn and use the angle template 'X' to obtain the correct incidence.

FINS: The fins are toed in and are upright in the front view. The best way to ensure fitting them accurately is as follows. Invert the wing and prop it up at zero incidence by insetting a support under the centre section (about 3-1/4 in high). Now attach the fins, checking for vertical alignment with a square placed on the building board. The outer edges of the fins are left flat and the inner faces rounded off at the leading and trailing edges.

FUSELAGE: Cement the 1/4 in sheet fairings (3) to either side of the fuselage (1). Cut a shallow 'V' for the wing seating and cement the wing in position. Add the cabin (2) and the piece of hardwood for the Jetex clip mounting. Carve the sheet fairings and the fuselage to shape, then finish off with fine sandpaper to the correct section.

JETEX MOUNTING: The Jetex clip is secured to the hardwood bearer and a loaded Power Unit attached. The model should balance at the point indicated..."

Quote: "Bill Dean also designed this simple sheet flying wing for the 100 unit. It was published in November 1948 in the first of a new series of 'Model Aviation' publications which Bill edited with Ron Warring. Flown at the first Jetex contest at the 1948 Isle of Man Rally, 'Jetwing' gained second place. At the same rally, it also gained fourth place in the Flying Wing Power event"

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.
