The ultimate “Ultimate” gear is now available!!! Critical RC now has our famous Ultra Flexible Carbon Landing Gear available for the Flex Innovations 70cc Ultimate Biplane!
Made with that famous Ultimate rake, but raised to allow the Critical RC Shock absorbing flexibility built into all our landing gear.
Ask anyone who has used Critical RC gear, and they will tell you nothing has ever been produced that even comes close!
Our Carbon Fiber Landing gear is an industry first. They were derived from hundreds of hours of flight testing over several years. Initially they were developed for 180 size profile 3D airframes.
Reassessing how a Landing gear should work it was very obvious it needs to do just that, WORK! By “Working”, I mean it has to actually flex across the whole gear from axle to, and through the fuselage mounting bolts. Also obvious was the fact that carbon fiber is incredibly strong but traditional layups make it very very stiff. This transfers all the landing loads directly to the fuselage and would break the wood mounting points on very hard landings. This was totally Unacceptable.
Through many variations using several types and weights of High Modulus carbon, I was able to produce a highly flexible landing gear that did exactly what I wanted. This gear flexed from the axle through the lower bend and carried through the upper fuselage bend. To facilitate the large flexing travel the gear needed to be higher. This actually makes the airplane sit nose high very similar to full scale aerobatic planes and large prop biplanes.
This gear is Ultra Flexible and yields to the landing surface always. The plane sits higher and allows flexing while preserving the prop clearance. The most important aspect of this is its ability to absorb the shock of hard landings and each jolt and jar from uneven surfaces and not transfer that immediately to the fuselage and mounting blocks. This is similar to crush zones and airbags in vehicles in that it dissipates energy through Flexural strength while diminishing the overall impact load.
This is truly an industry first and a game changer in landing gear technology.
Please try my gear on all your favorite Flex Innovations airplanes! Package deals available.
Enjoy this aspect of flight as much as I do with big deep harrier landings, one wheel to the other dragging wingtips and full throttle high speed takeoff rolls while laughing the whole time! Truly flying…. and landing as it should be!!!
