Javelin Glider (oz15462)
About this Plan
Javelin Glider. Free flight towline glider model.
Quote: "One of England's top authorities on gliding brings you this high-performance, easily built craft. Javelin Glider, by Ray Jessop.
Here is a glider of unusual lines that will repay anybody who builds it with a contest-winning performance. It will give non-thermal flights of 3 minutes-plus from 300-ft line every time and will take advantage of even the slightest trace of a thermal. Towline stability is excellent. It is about the minimum in size for maximum efficiency and is strong enough to stand the hardest knocks and stiffest breezes.
All materials are medium quality balsa unless otherwise stated. Build square fuselage to basic side view from 3/32 sq hard balsa. Former 1 is cut from 1/16 sheet and cemented in position. Four 3/32 sheet panels are cemented in first bay to form weight box. Nose block is then shaped from block balsa and glued in position.
Formers 2, 3, 4, 5, 6, & 7 (2 of these) are cut from 1/16 sheet, member 8 being cut from 3/32 sheet. The diamond section of the basic fuselage is merely obtained by turning the square fuselage through 45 degrees.
The cabin is next built in the following order: formers 5 & 6 are glued to basic fuselage as shown, followed by member 8 which is cemented in slot of former 6 and butted to former 5 and top longeron of fuselage at station 1. These are followed by formers 3 & 4. Wing platform 7 (2) is cemented to top of formers 3, 4 & 5. The top of former 2 is cemented to the front of wing platform and the bottom to station 1 on basic fuselage. Wing retaining dowels are then glued in position, being reinforced by two pieces of 3/4 x 1/8.
Top longeron of fuselage is cut away between station 3 and rear for stab platform. Tow hooks are bent from 13 ti" spring wire; these are hound and glued to bottom longeron. Fuselage is finally covered with lightweight tissue and given two coats of clear dope. Two 3/32 sq cabin supports are cemented in position; to these the celluloid cabin panels are cemented.
Cut fin members R1, R2, R3, R4, R5 & R6 from 3/32 sheet. R1, R2, R3 & R5 are then cemented in their correct positions, with 3/32 sq, forming the cross braces. The trim tab R4 is attached to this main fin with soft wire as shown. It is then covered with lightweight tissue and given one coat of clear dope. The main fin and sub fin R6 are then securely cemented to the fuselage in their appropriate positions.
For ribs of wings, first make an accurate plywood template of the airfoil section minus LE & TE. Using this template, cut 24 ribs from 1/16 sheet and 3 from 3/32 sheet... "

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.
