Carbon Fiber Undercarriage Questions

Why should I choose carbon fiber undercarriage over aluminum or steel?

Carbon fiber undercarriages offer several key advantages:

10x stronger than aluminum (500,000+ psi tensile strength vs 40,000 psi)
60% lighter weight for better performance and extended flight times
Superior flex and memory – bends under impact and returns to shape
Corrosion-proof – no rust or oxidation in wet conditions
Vibration damping – protects electronics and provides smoother operation
Longer lifespan – outlasts metal alternatives by years

Are your carbon fiber undercarriages made from solid carbon fiber?

Yes! Our undercarriages are constructed from full carbon fiber, not fiberglass with a carbon skin. This provides superior strength-to-weight ratio and durability.

Do carbon fiber undercarriages come pre-drilled?

No, all our carbon fiber undercarriages are supplied undrilled to ensure perfect fitment for your specific aircraft model. This allows you to customize the mounting holes precisely to your plane’s requirements.

What if I can’t find the right size undercarriage for my model?

If you can’t find a standard size that fits your aircraft, simply contact us with your A, B, and C measurements (see measurement guide below), and we’ll recommend the best option or discuss custom sizing possibilities.

Undercarriages

How do I measure for the correct undercarriage size?

To determine the correct undercarriage size, measure:

A measurement: Distance between fuselage sides or mounting exit
B measurement: Total width of the gear (tip to tip)
C measurement: Height from mounting surface to axle center / bottom of the undercarriage

Send these measurements to us via our Contact page, and we’ll help you find the perfect fit.

What aircraft sizes do your carbon fiber undercarriages fit?

We stock undercarriages for:

Electric models (40-60 size)
Nitro models (50-90 size)
Petrol/Gas models (20cc up to 150cc+)

From profile aerobatic planes to scale warbirds, we have options for various aircraft types and sizes.

Can carbon fiber undercarriage break on hard landings?

While carbon fiber is extremely strong, it can fail under extreme impact – just like any material. However, carbon fiber typically flexes and returns to shape where aluminum would permanently bend. With proper installation and normal use, carbon fiber undercarriages are far more durable than metal alternatives.

How do I maintain my carbon fiber undercarriage?

Carbon fiber requires minimal maintenance:

Wipe clean after each flying session with a soft cloth
Use mild soap and water for stubborn dirt
Inspect visually for cracks or white stress lines
Avoid harsh chemicals that could damage the resin
Apply UV protectant wax seasonally for extended life
If you wish to colour your undercarriage this is possible with a wipe of a good cleaner, and a light sanding to key the surface. Take good protective precautions with sanding or drilling carbon fibre.

Do you sell stub axles, wheels, and spats?

Yes! We carry:

Stub axles for carbon fiber undercarriages
Aluminum hub wheels (2.75″ to 5″ sizes)
Plastic hub wheels for various applications
Wheel spats and fairings to complete your scale appearance

What’s included with carbon fiber undercarriage purchases?

Our carbon fiber undercarriages are supplied as the landing gear struts only (undrilled). Mounting hardware, stub axles, wheels, and spats are available separately, allowing you to customize your setup exactly as needed.

Can I use carbon fiber undercarriage on my foam plane?

Yes! Carbon fiber undercarriage works excellent with foam aircraft. The reduced weight is particularly beneficial for foam models. Just ensure proper mounting through reinforced areas of the foam structure.

Are your wheels compatible with other brands of undercarriage?

Our wheels are designed to work with standard stub axles. As long as your undercarriage uses conventional axle sizing, our wheels should fit. Check axle diameter specifications or contact us to confirm compatibility.

Do you sell complete landing gear sets with wheels?

We offer undercarriages separately to allow maximum customization. You can add stub axles, wheels of your choice, and optional spats to create your perfect landing gear setup.

Ensure gear is perpendicular to the thrust line
Use reinforcing plates on the mounting area if needed
Check alignment and screw tightness after first few flights

Can carbon fiber be repaired if damaged?

Minor surface damage can be repaired with epoxy resin patches. For significant structural damage, replacement is recommended for safety. We can advise on repair vs. replacement based on photos of the damage.

What propeller should I use with my engine?
