Graph Tech Main Gear

Main Landing Gear Measurements

I have been designing and making composite main gear for over 9 years now. Over that time, I have made 70+ different lay-up schedules as well as try many different resins. The gear I have listed below are made with this experience and knowledge. There will be new gear added all the time. Be sure to check back often. The gear are made glossy black carbon unless noted. New Version 4D Lay-up is used in all 1.20 size gear and larger. This eliminates delamination and is twice as strong as the previous version in the bend. This is a proprietary process that you will only find in Graph Tech gear. It is the culmination of a year of testing and developing to achieve a sound platform for landing gear. Thinner laminates can be made stronger and carry better flex properties than with conventional lay-ups. This produces a thinner, lighter, and stronger gear. All gear are made with 100% Carbon Fiber. No Fillers. And the gear are Post Cured in an Autoclave (oven) for maximum strength.

Gear dimensions are: Base of fuse width / gear height / gear overall spread / the width of the gear at the fuse (front to back) and the width at the axle / gear weight.

*****NOTE: All gear are not drill. This gives you the ability to move the axle up or down almost an inch. Most dimensions are the total height of the gear. ******
