Frequently Asked Questions
- What is a pitch slider bellcrank and why does my Fusion 700 need one? — The pitch slider bellcrank is a critical linkage component in your helicopter's pitch control system. It converts control inputs from your transmitter into precise adjustments to the main rotor blade pitch, which controls altitude and lift. If this part becomes worn, bent, or damaged, your pitch control response becomes sluggish or imprecise, affecting flight stability and safety. Replacing it with the genuine BLH-1687 restores full control authority and smooth response.
- How do I know if my bellcrank needs replacing? — Signs that your bellcrank needs replacement include sluggish or delayed pitch response, difficulty maintaining stable altitude, loose or sloppy control feel, or visible bending or damage to the component. If you've had a hard landing or crash, inspecting and potentially replacing the bellcrank is recommended as part of post-incident maintenance.
- Is this a genuine Blade part? — Yes, the BLH-1687 is the genuine Blade factory part number for the Fusion 700 pitch slider bellcrank. Purchasing the correct part number ensures you're getting an OEM component that meets Blade's engineering specifications and guarantees proper fitment without modification.
- Will this part fit my helicopter? — This bellcrank is specifically designed for the Blade Fusion 700. Using the correct part number eliminates guesswork about compatibility. If you operate a different Blade helicopter model, verify the correct part number for your specific aircraft before ordering.
- How often should I replace this part? — Under normal flying conditions, a bellcrank should last for many flight hours. However, hard landings, crashes, or visible wear warrant replacement. Many RC helicopter pilots keep a spare on hand as part of their maintenance kit to minimise downtime if a bellcrank needs replacement.
- What tools do I need to install this? — Installation requires basic RC helicopter maintenance tools. Consult your Fusion 700 manual for specific installation procedures and any special tools needed for your particular helicopter configuration.
