How to Choose Used RC Airplanes

Buying a used RC airplane can be a great way to enter the hobby or expand your fleet without breaking the bank. However, it's essential to know what to look for to ensure you're getting a reliable and enjoyable aircraft. This guide will walk you through the key aspects of choosing a used RC airplane.

Inspection Checklist: Airframe

The airframe is the foundation of your RC airplane. Thoroughly inspect it for any signs of damage.

  • Check for cracks, especially around stress points like wing roots and control surface hinges.
  • Look for previous repairs. While repairs aren't always a deal-breaker, assess their quality and the extent of the damage.
  • Examine the covering (if applicable) for tears, bubbles, or peeling. These can affect aerodynamics.

Engine/Motor Assessment

The power system is critical. Its condition directly impacts flight performance.

  • For glow engines, check compression by flipping the prop. It should feel strong and consistent.
  • Inspect the carburetor for cleanliness and proper function.
  • For electric motors, examine the motor for any signs of damage or wear. Check the ESC (Electronic Speed Controller) for functionality.

Radio System Evaluation

The radio system is your control link. Ensure it's in good working order.

  • Verify that the transmitter and receiver are compatible and bound correctly.
  • Check the range of the radio system by performing a range test.
  • Inspect the servos for smooth operation and centering.

Battery Condition (Electric Models)

Batteries are a significant expense. Assess their health carefully.

  • Check the battery's physical condition for any swelling or damage.
  • If possible, test the battery's voltage and capacity using a battery checker.
  • Inquire about the battery's age and how it was stored.

Landing Gear and Control Surfaces

These components are crucial for safe takeoffs and landings.

  • Inspect the landing gear for any damage or looseness.
  • Check the control surfaces (ailerons, elevator, rudder) for free movement and proper linkage.
  • Ensure the hinges are secure and not worn.

Price and Value

Determine a fair price based on the airplane's condition and included equipment.

  • Research the original price of the airplane and its components.
  • Factor in the cost of any necessary repairs or replacements.
  • Compare prices of similar used models to get a sense of the market value.

Where to Buy Used RC Airplanes

Several avenues exist for finding used RC airplanes.

  • Online marketplaces like Usato-RC.
  • Local RC clubs and forums.
  • Classified ads in your local area.
  • Consider the seller's reputation and feedback.
