Fun Science 2009 Kit – Middle School

This plane is designed to meet “B” Division Science Olympiad specifications.  The 2009 rules stipulate only monoplanes are allowed and must have a minimum weight of 7 grams.  This kit utilizes the maximum wingspan of 40 cm with a 12 cm chord. It also utilizes the largest horizontal stabilizer allowed with an extra long tail boom to enhance flying qualities.   These planes, when constructed and adjusted correctly (and flown in a LARGE building), should have over 3 minute capabilities.

This is a 2 airplane kit.  It contains 2 fixed pitch Ikara propellers and all hardware to build top-notch competition planes.  Easy to adjust and forgiving to fly.  All wood carefully considered to yield enough strength and durability yet be built to minimum weight requirements when following instructions.  Basswood is used in key locations to enhance durability.  Packaged with ultra light Mylar covering.  Includes a covering cradle (fixture used to hold Mylar to allow easy application.)  Custom cut rubber in 3 different widths is also included in every kit.

This kit is designed to meet TSA (Technical Students Association) “Flight Endurance” specifications for the years 2009 - 2010 and can be modified for the Science Decathlon “Cranefly” event. TSA rules require a ROG (Rise off Ground) takeoff, so landing gear is included. This kit is very adaptable and can be easily modified for the student’s preference. It includes an Aerodynamics lesson and many insights into flight trimming for best performance.  Previous versions of the kit have won several National Championships.

This is a 2 airplane kit. It contains 2 fixed pitch Ikara propellers (NO SHAVING NECESSARY!) and all hardware to build top-notch competition planes. Easy to adjust and forgiving to fly.
 Construction utilizes some basswood to increase durability in key locations and when built per instructions should weigh under minimum weight (clay for ballast included). Extra light balsa and slicing guides simplify the task of slicing ribs. Packaged with ultra light Mylar covering (new this year). Custom cut rubber in 3 different widths is included in every kit.

Ikara Propeller Assemblies (Legal for SO competitions)

Includes extra light propeller assembly weighing approximately 1.8 grams.  No shaving necessary!  Blade material is approximately .009" thick. Measures 8 7/8” diameter (22.5 cm) and can be trimmed with scissors to meet some competition rule requirements.  Hub can be bent with pliers to alter pitch.  This is the same propeller that is included in the kits above.

24 cm diameter with the same construction and materials as the standard Ikara propellers but a much wider chord located mostly ahead of the spar.  This allows the thin plastic blades to slightly flex to a steeper pitch at the beginning of the flight to slow down the climb, but then flex back to the original flatter pitch for the remainder of the flight. This is a method of making somewhat of a variable pitched prop. These propellers are excessively wide so instructions and a template are provided to show how to trim them with scissors for maximum performance.

This is the small plastic piece that is glued onto the forward end of the Motor Stick to receive the Ikara propeller assembly.  This set up allows for quick and easy propeller removal or change.  Mounting ring measured .203” I.D. or .51 cm and weighs .09 gram.

This is the small plastic piece that is glued onto the rear of the Motor Stick that the end of the rubber motor will hook onto. Measures approximately .200” or .5 cm long and weighs .035 gram.

New and improved. Now constructed of basswood with a larger protractor to allow easier measurement of the broad blade propellers. Designed to be used with the Ikara propeller assemblies. Allows you to easily slip your propeller off of the airplane and onto this gauge. Used to accurately measure pitch (angle) of the propeller blades after bending the plastic hub. This is an important tool to maximize flight performance by matching your propeller pitch to the rubber band that you are using for the size of the building that you are flying in.

This kit will allow you to cut your own blade profiles from precambered .008” plastic and glue them to wooden toothpick spars that are friction fit into a center hub. This allows the ultimate in freedom to experiment and discover what works best for your airplane. Also included are all mounting hardware (including propeller hangers) and Ikara hub to allow building custom fixed pitch versions. Depending on your blade profile, entire assembly will weigh from 1.4 – 2 grams. ATTENTION: "Wright Stuff" event director has interpreted the propeller rules as meaning commercially "ASSEMBLED". He now has deemed these propellers as an unfair advantage and are therefore illegal for "Wright Stuff" competition. Much can be easily learned with these propellers that will directly apply to becoming a champion in this event. These kits come with all mounting hardware (including nose hangers) to make them useable on other models as well.

Extra Propeller Blade Material
(4 precambered .008” plastic sheets with wooden toothpick spars)

This will allow you to build multiple replacement blades for the adjustable hub and experiment with different blade profiles.

Collapsible Fiberglass Pole (4' collapsed - 20' extended)

Collapsible fiberglass poles that measure 4' when collapsed and 20' when extended.  This product is used to aid in model retrieval from the rafters or basketball goals.
