Adding weight to a boomerang is generally done to increase momentum, which results in a longer distance and greater wind stability. The easiest way to add weights to your boomerang is to tape coins, or small pieces of lead to the bottom of the wing(s). The following rules of thumb should be taken into consideration when trying to modify the weight of your boomerang:
* The closer to the tip of the arm the weight is placed, the greater the effect will be.
* Adding equal weight to each wing will result in a longer, slightly more eliptical trajectory. The throw should be adjusted by using more tilt and throwing more into the wind.
* Adding equal weight to each wing and a weight 1/3 as heavy to the elbow will keep the flight similar to the unweighted flight, but will increase the distance. The throw should be adjusted by using more tilt.
* Adding weight to the lead arm only will delay the lie-down, increase distance, and reduce or eliminate the hover. The throw should be adjusted by adding more tilt, throwing lower, and more into the wind.
* Adding weight to the dingle arm only will produce an earlier lie-down, reduce the distance, increase the hover, and result in a higher flight. The throw should be adjusted by throwing higher and holding the boomerang more vertical.
