Elastic Launched Glider 2019 – Full Kit

Designed to meet 2019 Division “B” ELG specifications. This kit includes materials to build 4 gliders as well as thorough instructions, 2 sanding fixtures, a two-sided sanding bar, an empty glue bottle (to allow mixing model cement and acetone for Carbon Fiber attachment) and precision tips for controlled application. Two simple launch handles with 2 sizes of rubber. It features specially selected balsa wood that is laser-cut for precision, special foam for flexible trailing edge flaps and two sizes of Carbon Fiber Tow (3K and 1.5K). Substantial sanding will be necessary for championship results. Detailed instructions for building and flying are included. Finished gliders measure 30 cm wing span, 32.5 cm long and should build up to close to the minimum allowable weight of 3.5 grams.

This is considered a “flapper” design where the trailing edge of the wing is flexible and cambers into “flaps down” position at slow speed. Excess lift provided by a wing that flies well at low speed could cause a glider to loop upward during a hard launch. Flexible flaps allow the trailing edge to lift and straighten, reducing lift during the high velocity launch. Then when maximum altitude is reached the plane slows and the trailing edge drops to its normal “flaps down” position to allow a long elegant circular glide downward.

A removable wing has been incorporated that allows easy incidence adjustment as well as more damage resistance in the event of a hard crash. For practice flying, tiny dental rubber bands hold the wing securely into position (included) but will need to be replaced with masking tape or glued into place for competition flying because of current competition rules.

Fun Science 2019 “Tandem” Full Kit (2 airplanes)- High School

Designed to meet 2018-19 Division C “Wright Stuff” specifications. This is an entirely NEW kit that utilizes carbon fiber rods for key components to reduce warpage issues, increase aerodynamic efficiency, increase strength but still allow building near minimum weight. It has an innovative aerodynamic approach using a giant horizontal stabilizer that is as large as the wing. The ribs are laser-cut to build completed wings that are a full 35cm with a 7cm chord. There are numerous adjustable components allowing for the ultimate in learning, experimentation and flying success!

This kit will build two complete airplanes. It contains two Ikara 24cm symmetrical propellers and all hardware to build top-notch competition planes. Including a large instruction package and full-sized drawing to provide even novice builders with the step by step construction process and a full aerodynamics lesson for insights on how to fly and achieve maximum results. All wood is carefully selected to yield enough strength and durability yet be built close to the minimum 8 gram weight requirements. Carbon Fiber Tow is included to reinforce the motor stick, along with an empty glue bottle (allows mixing model cement and acetone) and precision applicator tips for accurate glue application. It is packaged with ultra-light Mylar covering and includes a covering cradle. Custom cut rubber in 3 different widths (13g each) is also included.

This airplane will require a winder (not in kit) to fly long duration flights (available on the TOOLS page - 15:1 ratio recommended).

ELG 2019 – Partial Kit

This PARTIAL KIT includes ONLY materials to build 4 gliders. It includes the high-quality laser-cut balsa, foam flap material, Carbon Fiber Tow, clay and dental elastics to mount the wings.

To help insure success, do not order this kit unless you have already ordered the FULL KIT. This partial kit DOES NOT include any instructions or paperwork. It DOES NOT include sanding fixtures, sander, glue bottle or launching devices.

Fun Science 2019 “Tandem” Partial Kit

This PARTIAL KIT contains all the materials to build 2 more airplanes. It contains all laser-cut parts including ribs, wing mounts and tail pieces as well as motor stick material. It also has 3K Carbon Fiber tow for balsa motor stick reinforcement, two sizes of carbon fiber rods, and hardware bag (same as in the full kit, including all plastic pieces, and misc. small parts). It also has a roll of Mylar and two 24cm symmetrical propellers. Multiple partial kits may be packaged in the same box.

This PARTIAL KIT does NOT contain any instructions, drawings, rubber, building fixtures or covering cradle. Do not order this unless you already have all these items from a FULL KIT.

TSA – Flight Endurance

Though an entirely new kit specifically made for this event is not available yet, Dave has written up modification instructions for the FS2018 kit that makes use of more contemporary Carbon Fiber materials as well as Balsa Wood. When ordered, you will receive the FS2018 Kit, but it will have larger propellers and rubber, sized for these TSA rules. It will also have materials included to make the necessary landing gear. It will still require some creative thinking and modifying laser cut parts, but the instructions will make it reasonably straight forward.

A rubber winder will be required.
