Tuning
Mastering the Adjustment
If your boomerang isn’t returning to your hand, it may not be your throw—it might just need a tune. Tuning is the art of bending or twisting the wings to compensate for wind, material memory, and accuracy. This process utilizes physical bends as well as tape, rubber bands, lead weights, and flaps to adjust flight dynamics.
The Dihedral
Bend the wings slightly upward (away from the flat side) to increase lift. This makes the boomerang fly higher, hover longer at the end, and return more quickly.
The Anhedral
Bend the wings downward to reduce lift. This results in a lower, more “cruising” flight path. Use this on very windy days to prevent the boomerang from being blown over your head.
Positive Twist
Twist the Leading Edge of the wing up (Angle of Attack). This creates more drag and a tighter, faster turn. Ideal for small fields or Fast Catch events.
Negative Twist
Twist the Leading Edge down. This opens up the circle, allowing for a wider, more soaring flight path. Essential for Long Distance and Aussie Round models.
Weight Tuning
Adding lead weights or lead tape to the underside of wingtips or the elbow increases rotational inertia. This helps the boomerang “punch” through wind and increases stability. Weights can also be applied to the top side for specific flight path changes.
Field Adjustments
Rubber Bands: Placed under wingtips to increase drag, aiding in stability and path changes.
Flaps/Tape: Flaps of tape create drag and disturb airflow over the tips to adjust accuracy, similar to rubber bands.
Tuning Strategy
A common, effective technique is adding weight (lead tape) to the underside of wings for wind, or adding drag (rubber bands) to the outside wings for better stability during flight.
The Material Rule
Wood: Flex the wings and hold for 10 seconds to set the “memory.”
Plastic: Some polymers require dipping in hot water to soften before bending to prevent snapping.
Pro Tip: Small Changes, Big Results
Never apply aggressive bends all at once. Make a tiny adjustment, test the flight, and observe. A 1mm change in dihedral can alter the return point by several meters. Always tune for the current wind conditions on the field.
Note: Lead weights, tape, and rubber bands handle wind and improve return accuracy by manipulating momentum and airflow disturbances.
