Helicopter 2011 Full Kit


This kit was designed specifically for Science Olympiad competition. It contains all materials to build two complete 40 cm span rubber powered helicopters. It contains laser cut, cambered ribs and fixtures to allow building symmetrical, warp free rotors in both clockwise and counter clockwise pitch configurations. It also contains covering cradles to aid in attaching the included Mylar to the completed framework. Step-by-step instructions help to insure success by even novice builders. There is an aerodynamics section to discuss how these helicopters work and what to look for to find increased success. These helicopters should build up to less than 4 grams weight, allowing ballast to be added low on the frame to enhance stability. 30 Grams of .125” FAI Tan Super Sport rubber is also included. A winder (see below) will be necessary to maximize the energy stored in the rubber motor.

Fun Science 2010 Kit – Middle School


Designed to meet “B” Division Science Olympiad specifications, and is a complete redesign from last year’s kit. This kit is based on the 2009 National Championship winning plane. It features sharp, drooped leading edges and laser cut ribs making it easier to build than previous models. This kit utilizes the maximum wingspan of 40 cm with a wide 15 cm chord. It also utilizes an extremely large horizontal stabilizer to enhance its flying qualities. These planes, when constructed and adjusted correctly (and flown in a LARGE building), should have well over 3 minute flight 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. It is packaged with ultra light Mylar covering and 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 (enough for at least thirty 1.5 gram rubber motors).

redbulletIndoor Flyer 2009

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.

redbulletScience Decathlon 2009 Kit
(was Fun Science 2007 and 2008)


This plane meets all Science Decathlon “Cranefly” specifications for the years 2008-2009. It was originally designed for Science Olympiad competitions from the years 2007-2008 and will still have this identification on the instructions and drawings.  The rules stipulate only monoplanes are allowed and must weigh a minimum of 7 grams.  The wingspan is 50 cm and the chord is 7 cm.  These planes, when constructed and adjusted correctly (and flown in a LARGE building), could have up to 4 minute capabilities.

Freedom Flight ModelsredbulletWinder - 15:1 Ratio

Built by K & P in England (smooth, high quality - yellow) and is the winder of choice of most top competitors.  A quality winder is essential to “feel” the torque of the rubber while winding to achieve maximum performance.

       $ 20.00
Freedom Flight ModelsredbulletPropeller Pitch Gauge

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.

       $6.00

Freedom Flight ModelsredbulletIkara Propeller - 8 7/8"
(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.

Freedom Flight ModelsredbulletBroad Blade “Flaring Style” Propeller Assy. (Legal for SO competitions)

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.

       $ 4.50
Freedom Flight Modelsredbullet2 Propeller Kit - Ground Adjustable with Hardware

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.

       $ 9.00
Freedom Flight ModelsredbulletExtra 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.

       $ 8.00
Freedom Flight ModelsredbulletFront Hook

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.

       $ .50 each
Freedom Flight ModelsredbulletRear Hook
