説明
Every Landing Begins Long Before the Wheels Touch Grass. The final five seconds of an RC flight — the approach, the flare, the touchdown — are where reputations are made and airframes are broken. The landing gear is the single component that absorbs the cumulative kinetic energy of an entire flight in one brief moment of contact. When that gear is aluminum, every rough strip, every gust-driven drop, every slightly-too-fast touchdown sends shock waves through the fuselage that accumulate into microfractures you will not see until the gear leg folds on a routine landing six months later.
The Strong Extra 260 Carbon Fiber Landing Gear replaces that failure mode with a material that flexes where aluminum bends and returns to form where aluminum stays deformed. Carbon fiber's anisotropic properties — stiff along the fiber axis, compliant across it — make it the ideal material for landing gear: rigid enough to maintain geometry on takeoff, compliant enough to absorb impact on landing. For 26cc to 50cc gas-powered airframes in the Extra 260 and similar aerobatic platforms, this gear set is a direct bolt-on upgrade that subtracts weight and adds durability in a single swap.
At the field, the difference is audible. An aluminum gear set produces a sharp metallic clack on touchdown that signals impact transfer to the airframe. Carbon fiber produces a muted thud — the sound of energy being absorbed rather than transmitted. After a season of flying, the aluminum gear pilot is tightening mounting bolts and chasing stress cracks. The carbon fiber gear pilot is flying.
You do not rise to the level of your flying. You fall to the level of your landing gear.

Application Scenarios
This landing gear set is purpose-built for the giant-scale aerobatic RC pilot who flies from grass strips, dirt fields, or less-than-perfect runways. The Extra 260 airframe class (wingspans typically 78-107 inches) demands landing gear that can handle the weight of a 15-25 pound aircraft touching down at speed. Gas-powered aerobatic airframes in the 26cc-50cc range are the sweet spot — smaller electrics do not generate enough landing stress to justify carbon fiber, and larger 100cc+ aircraft require heavier-duty gear sets. IMAC competitors and 3D freestyle pilots will notice the weight savings immediately in vertical performance and snap-roll crispness. Club flyers who operate from rough fields will appreciate the impact absorption that prevents the cumulative damage that turns a minor hard landing into a major fuselage repair.
Frequently Asked Questions
Q: Does this fit my specific airframe model?
A: This gear set is designed for the Extra 260 platform and similar 26cc-50cc aerobatic airframes. The bolt pattern is standard for this class. However, always measure your existing gear's bolt spacing before ordering — mounting dimensions vary slightly between manufacturers. If your bolt centers are within 3mm of standard Extra 260 spacing, the gear will fit with minor elongation of the mounting holes.
Q: Is carbon fiber really stronger than aluminum for landing gear?
A: "Stronger" depends on the direction of force. Carbon fiber has 3-5× the tensile strength of aluminum along the fiber axis, and its fatigue life is effectively infinite (aluminum has a finite fatigue life — it WILL eventually crack under repeated stress cycles). In the vertical loading direction that landing gear experiences on touchdown, carbon fiber is unequivocally superior. If you crash laterally (cartwheel), carbon fiber may shatter where aluminum bends — but at that point the landing gear is the least of your concerns.
Q: Do I need special tools to install this?
A: No special tools required. The gear uses your airframe's existing mounting bolt holes. You will need the appropriate hex driver or Allen key for your mounting bolts (typically M3 or M4). Apply a small drop of blue threadlocker to each bolt during installation — carbon fiber and metal bolts can vibrate loose over time without it.
Q: How much weight will I save?
A: Typical weight savings over stock aluminum gear is 30-40%, which translates to roughly 80-150 grams depending on the size class. On a 26cc airframe, 100 grams off the landing gear (the farthest-forward weight on the aircraft) can noticeably improve pitch authority and reduce the need for nose weight to achieve CG.
Q: Will the clearcoat yellow over time?
A: The UV-resistant clearcoat is formulated to resist yellowing under normal field conditions. However, all clearcoats degrade with prolonged direct sun exposure. Store your aircraft under a canopy or wing bag at the field, and the finish should remain clear for multiple seasons. If cosmetic degradation occurs, the structural integrity of the carbon fiber underneath is unaffected.
