Frequently Asked Questions
- What is the difference between the A6320 and other Spektrum aircraft servos? — The A6320 specifically combines brushless motor technology with ultra-torque and high-speed capabilities, distinguishing it from standard metal gear servos. The brushless design eliminates brush wear, delivering superior longevity and consistent performance throughout the servo's operational life, whilst the dual high-speed and ultra-torque characteristics make it exceptionally versatile across various RC aircraft applications.
- Is the Spektrum A6320 suitable for beginners? — Whilst the A6320 is a high-performance servo suitable for advanced applications, its reliability and digital precision make it appropriate for any modeller upgrading from basic servos. Beginners should ensure their RC aircraft's control surfaces are designed to accommodate this servo's torque output, and that their receiver and battery system support high-voltage operation.
- What voltage does the A6320 require? — The A6320 is a high-voltage (HV) servo, meaning it operates at elevated voltage levels to maximise torque and speed output. You should consult your receiver specifications and battery configuration to ensure compatibility with HV servo operation before installation.
- Can I use the A6320 in salt water or harsh environments? — The A6320 features metal gear construction that resists corrosion better than plastic gear alternatives, however, standard RC servos are not fully waterproofed for submersion. For salt water or extremely wet environments, additional protection or sealed servo alternatives should be considered.
- How does brushless motor technology benefit me? — Brushless motors eliminate the carbon brushes found in conventional servos, removing a primary wear component. This results in extended servo lifespan, reduced maintenance requirements, and more consistent performance over extended use periods, particularly valuable for serious RC aircraft enthusiasts in the UK who fly regularly.
- What aircraft types work well with the A6320? — The A6320's combination of high torque and high speed makes it suitable for large-scale aerobatic aircraft, precision control platforms, and any application demanding reliable, responsive servo operation. Its compact design allows installation in space-constrained airframes without compromising functionality.
