How to Throw Boomerangs

Check for Warp

To check for warp while out throwing, hold from the lead arm (righties). Sight straight down the edge of the 'rang. If the 'rang is warped you will see the profile (or partial profiles) of the far arm. Check both arms of the boomerang. Slight warp can have significant effects on the flights. Bend the boomerang accordingly to correct the warp. Slight tips up warp is ok (if painted side is top).
	Lay the boomerang on a perfectly flat surface, painted side up. Slight clicking just at the tips is what you want. Be sure to check both arms.

When your boomerang consistently sinks on the outbound part of the flight... Check warp, bend the tips up.

When your boomerang climbs too high, too fast... check the warp. Try bending the tips down so the boomerang is flat.
