These carbon landing gears combine aesthetics and function into one light weight package.

Carbon Fiber Landing Gear 25grams

The Carbon Fiber Landing Gear as it appears on the Chiros 2


These carbon fiber landing gears are constructed with 100% continuous carbon fiber tow and high temperature epoxy. No silicone mold releases are used to allow for painting if desired.  The carbon fiber gear allows for a smaller cross section with less drag and less weight than is obtainable when using aluminum.  The gear is designed for three 4-40 mounting bolts, two in front and one in back.  The weight of these landing gears are approximately 25 grams each.  This will usually amount to a 50% weight savings over an aluminum gear.  Any time you can cut out weight that is hanging below the vertical center of gravity or below the airplane you will enhance the inside cornering and overall performance of the airplane.  The center section of this gear is 2 1/2 inches wide to accommodate today's stunt fuselage dimensions.  Dimension from the front of the landing gear to the aft on the flat mounting pad is 1 1/4 inches.  Gear height is   3 7/8 inches with a span of 12 1/2 inches. There are two versions of the three bolt carbon fiber landing gears available.  30 grams stiff and 25 grams normal.  The stiffer gear will work well on airplanes in excess of 60 ounces.  Specify 25 grams or 30 grams when ordering. 


Prototype carbon fiber landing gear with a hump in the center for tuned pipe clearance.  The hump tapers downward in  back providing extra clearance for the leading edge of the wing.  The gear pictured is going to be used as a plug to make the carbon fiber landing gear mold.  This gear like the others utilizes an airfoiled cross section.  


Close up of the carbon fiber hump gear center section.  The gear is designed to be mounted with four bolts.  Notice the downward taper of the hump to allow the carbon fiber gear to nest under the leading edge section of the wing.


This carbon fiber gear is designed to mount with four bolts.  The enlarged mounting plate will allow this gear to drop in place on the SV-11piped series of airplanes.  The cross section of the gear legs are a teardrop configuration to allow for rigidity and less drag. The weight of this gear is 34 grams.   One advantage of a carbon gear is the ability of the gear to flex without loading.  Aluminum seems to load under a landing  and spring back creating a bounce. Carbon fiber gears seems to absorb more of the airplanes inertia creating less chance for a bounce.  The dimensions of this gear match the SV-11 piped kit gear that Randy Smith of Aero Products sells.  The span of this gear is 12 1/2 inches.  I have extended the axle legs to accommodate a larger propeller if needed.  If the axle leg is too long they can be trimmed to suit the propeller ground clearance.  The span of the mounting plate is 2 5/8 inches and 1 3/8 inches deep.  This gear would also work great on other tuned piped airplanes of the same configuration.  


Disregard the nicks and dings  they will be filled later with balsa or putty.  When mounting the carbon fiber gear it is beneficial to use washers under the bolts to spread the load over a greater area also aluminum bolts would help save weight over the conventional steel.  The landing gear cutout is lined with 1/64 plywood to give a cleaner looking installation.  The 1/64 plywood is used around the cowling also.

The axle pads on all of the carbon fiber landing gears are reinforced with carbon fiber cloth for extra strength in this area.
