Ruth's sister International Power Cord 325mm Carbon Fiber 450 Series

SKU CH-CMFE-NHRAX

Glass-fibre main rotor blade set, 325 mm long and 33 mm wide, fits 450 series RC helicopters and weighs 50 g

  • Stable flight from carbon-fibre construction
  • 325 mm length fits 450-series helicopters
  • 33 mm chord width for strong lift
  • 8 mm thickness resists crash damage
  • 3 mm copper-sleeved aperture ensures secure mounting

Glass Carbon Main Rotor Blade

This carbon-fibre main rotor blade measures 325 mm overall length and is built as a direct replacement part for 450 series RC helicopters. The glass-fibre construction aims to deliver strength and crash resistance for pilots who want durable spares. A 3 mm aperture with a copper sleeve fits the standard rotor hub on these models. Buyers who need a different length or a blade set for a larger class helicopter will not be served by this item.

Sustained Flight Performance

The blade weighs 50 g and uses carbon-fibre material rated for stable flying under continuous rotor load. Width is 33 mm and thickness is 4.8 mm, providing stiffness that resists flex during extended manoeuvres. The glass-fibre lay-up is designed to stay hard on impact, reducing the chance of mid-air failure during long sessions. Pilots who demand telemetry feedback or active balancing built into the blade will not find those features here.

Installation and Common Issues

Mounting uses the existing 3 mm bolt hole with the supplied copper sleeve, so no special tools are required for a direct swap. The package includes one set of main blade propellers ready to fit. A tolerance of 1 to 2 cm on manual measurements means the exact length may vary slightly from the nominal 325 mm figure. Builders who require matched pairs weighed to tighter tolerances or pre-drilled alternative hole patterns will need a different product.

Questions about this item

How much does the 325 mm carbon-fibre blade weigh during long flights?

Each blade set weighs 50 g, keeping rotational mass low for extended sessions.

What rotor-head bolt size matches the 3 mm aperture with copper sleeve?

The blade accepts a 3 mm bolt; the copper sleeve protects the hole from wear.

Will the 33 mm chord fit the 450 series rotor hub I already own?

Yes — 33 mm width and 3 mm aperture are standard for 450 series hubs.
