Freedom Flight Models will be releasing a NEW 2017 version featuring carbon fiber components in late November to meet the new TSA regulations.


15 cm Propeller Assembly

This 15 cm diameter propeller is manufactured by Ikara and can easily be trimmed with scissors to the new Science Olympiad 14 cm regulations. This is a very light-weight efficient propeller where the whole propeller assembly weighs less than 1 gram. It is the same as included with the NEW 2017 Fun Science kits. The photo is of 2 propellers to show side and front view but are priced individually.

       $ 3.00

Freedom Flight ModelsredbulletNEW 24 cm Propeller Assembly

This 24 cm diameter propeller is manufactured by Ikara for Freedom Flight Models. This is one of the most efficient non-flaring propellers yet and is very easy to get GREAT results. It is the same as included with the NEW 2015 Fun Science kits. Weight is approximately 2.2 g. and has a 4 cm maximum chord width. Photo of 2 props to show side and front view but are priced individually.

Freedom Flight ModelsredbulletBroad Blade “Flaring Style” Propeller Assy.

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 and conserve winds, 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 but still comply with S.O rules. These propellers are a bit heavier at 2.8 g and are commonly sanded and trimmed. Photo shows side and front views but are priced individually.

       $ 4.50

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. It does include the pre-installed .020” shaft and Nose Button. Use a Front Hook (as shown below) to mount to motor stick – not included.



       $ 3.50

Freedom Flight ModelsredbulletPropeller – 9 ½” Molded Orange Plastic (Used with “Science Buddies” Experiment)

This molded plastic propeller is ideal for the “Efficient Propeller Design” experiment written up on the Science Buddies website. It is manufactured for outdoor rubber powered airplanes, and has a nice wide 1 5/16” chord, making it an excellent choice to trim down to narrower widths for experimentation. The original center hole is 3/64” diameter, but we will custom drill it to friction fit onto the 2mm shaft motor recommended in the experiment. If ordering these propellers for rubber powered flying, please send an e-mail asking us not to resize the center hole. For best results with the experiment, trim an even amount from the leading and trailing edges to make narrower chords. The experiment recommends 4 propellers, but commonly 6 are ordered in case spares are necessary.

redbulletTorque Meter

This tool is valuable to quantify how much torque is in your wound rubber motor.  It is always best to wind off of the airplane to avoid damage if the motor should break while winding.  This tool is used by hooking one end of the rubber to the meter and the other to your winder, then stretch wind to maximum torque, reading the scale on its face to observe the inch ounces of torque applied.  If the rubber breaks, you learned from the experience and nothing else was broken.

However the most valuable use is to observe the torque left when De-winding to control altitude.  Can help to build confidence and consistency.
Designed with a winder box to hold our yellow K & P winders (winder NOT included).  It has all hardware for mounting to a board (not included – shown is a 1 x 3 x 33”).
