RC ERA C170 Main Blades 4PCS Rotor Set for 1:48 Scale Apache RC Helicopter

Fix Aerodynamic Tracking Slop, Eliminate Shaking Vibrations, and Restore Crisp Pitch Thrust for 3D Aerobatic Maneuvers

The main rotor blades are the most vital components for generating the vertical lift and precise cyclic pitch changes required to maneuver your aircraft. For a highly technical 1:48 scale model like the RC ERA C170 Longbow Apache, spinning a complex four-blade flybarless head setup means any slight blade damage impacts stability. Blade strikes during tight indoor flights or hard outdoor tip-overs can easily nick, warp, or crack these high-speed airfoils. Flying with unbalanced or chipped rotors generates heavy, destructive high-frequency airframe vibrations that degrade servo performance, loose heading hold, and blur your flight profile. Replacing your damaged set with these factory-original RC ERA C170 main blades instantly restores stable lift vectors, whisper-quiet rotation, and rock-solid tracking accuracy during aggressive inverted 3D stunts.  Ships worldwide.

Product Highlights

• Scale-Accurate Matte Gray Texture: Molded with a professional military-style finish as shown, detailed with white accent borders and red diamond inspection pattern markings.

• Aerodynamic Swept-Back Wingtips: Features specialized curved trailing edge tips designed to reduce blade vortex drag, lower operational sound, and improve high-speed cruising lift.

• Factory Dynamic Weight Matching: Every 4-piece set is precisely weight-sorted at the factory to guarantee identical center-of-gravity properties, minimizing mechanical rotor head stress.

• Tough High-Impact Composite Mix: Built with a specialized rigid polymer compound that resists bending and stretching under intense aerodynamic loads during 3D aerobatics.

Compatibility

For the RC ERA C170 1:48 Scale Longbow Apache RC Helicopter only.

What’s in the Box

• 1 x RC ERA C170 Main Blades Set

Install Tips

• Removing the Damaged Rotor Blades: Use a precision micro screwdriver to unfasten the retaining screws from each blade grip on the four-way main hub assembly; slide out the old worn blades.

• Orienting and Seating the New Blades: Take a fresh blade from the pack and slide the mounting root hole directly into the metal grip slot, ensuring the clean matte finish with the white edge border faces upward in the direction of spin.

• Adjusting Grip Fastener Pivot Tension: Re-insert your original fastening screw and nut; tighten the bolt down until snug, but leave enough clearance so the blade can still swing smoothly forward and back under light finger pressure (over-tightening causes severe shaking on startup).

• Pre-Flight Balancing and Tracking Calibration: Manually extend all four blades straight out to align them 90 degrees apart; spin the head by hand to check that all tips travel along the exact same horizontal tracking plane before powering up your RC ERA C170 for takeoff.
