Ruth's sister 325mm Main Rotor Blades for 450 Series RC Helicopter internal power cable

SKU CH-WVCV-T6ZB3

Glass-fibre main rotor blades, 325 mm long and 33 mm wide, fit 450-series RC helicopters

  • 325 mm length fits 450-series helicopters directly
  • Glass-fibre construction resists impact during hard landings
  • 3 mm copper-sleeved aperture ensures secure bolt fit
  • 33 mm chord width delivers stable lift
  • 50 g weight keeps rotor disc light

Compatibility and Dimensions

These 325mm main rotor blades fit 450 series RC helicopters including the Trex 450 line. Each blade measures 33mm wide and 4.8mm thick with a 3mm aperture fitted with a copper sleeve.

Usage Guidance

Pilots looking for durable glass-fiber rotors for 450-class models will find this set suitable for stable flight and crash resistance. Builders needing carbon-fiber blades or a different length should select another part.

Material and Aperture

The blades are constructed from carbon fiber despite the glass-fiber mention elsewhere, and the 3mm hole with copper sleeve determines whether they mount on your specific rotor hub.

Questions about this item

How well do the 325 mm carbon-fibre blades hold up during long 3D sessions?

The 3 mm root aperture with copper sleeve spreads bolt load evenly, so the 4.8 mm thick blades resist cracking through extended inverted and tic-toc manoeuvres.

Do the 50 g blades create noticeable vibration or motor heat on a 450-size heli?

Precision-balanced glass-fibre construction keeps vibration low, reducing ESC temperature rise and tail-wag during prolonged hover and fast forward flight.

Which rotor-head bolt size matches the 3 mm aperture on these blades?

The 3 mm hole fits standard M3 feathering-spindle bolts used on Trex 450 and compatible 450-series heads, so existing hardware works directly.
