Boomerangs can be grouped by several of their parameters, though we can emphasize two of them that are the most essential of all.
The 2 ? generally straight ? blades enclose an angle of 80° to 120°. The airfoil is traditionally formed. Flight-distance between 30 to 50 meters mostly. Easy to throw, easy to catch, thus easily manageable. Drawback: shape is not very exciting, more sensible to wind changes in case of lighter types.
Usually smaller and lighter than classical V-shapes, blades enclose an angle of 70° to 110°. Blades do not grow narrow at the end this way they keep their drive / momentum for longer. Advantage: easy manageability, drawback: again more sensible to wind changes. Very good for beginners.
Thanks to its shape reminding us to the Greek letter, omega its flight characteristics differ significantly from other 2-bladers?. Advantage: less sensible to wind changes, fascinating view (they slice the air easily while flying along a regular cyclic path with a diameter of 40 to 60 meters).
Drawback: more technical experience is needed to throw and to catch them.
Transition between modern 2-bladers and omega shapes.
Advantage: less sensible to wind changes than most of the others, easier to throw and to catch than omega shaped at the same time a bit more difficult to manage than modern V-shaped ones. Flight distance range between 30 to 60 meters.
Manageability is similar to omega shaped but their flight path is more elliptic than cyclic. Drawback: sensible to wind changes at the same time their shape opens the door to imagination therefore very often you can meet some animal shapes among them.Flight distance usually ranges between 30 to 60 meters.
Angle of inclination of the blades is around 90°, one blade is remarkably longer than the other is. Light, flat boomerangs, their flight path is irregular and they not necessarily return to the starting point, in return they stay in the air much longer than the others do. This is the reason for their name as well, MTA (Maximum Time Aloft). Used in MTA competitions.
These boomerangs are available in various shapes and therefore can even more serve as a home décor object than others.
Their flight characteristics are within a wide range but generally they are more difficult to manage than modern 2-bladers and they have a less regular flight path than omega shaped ones.Of course some of them synthesize just the advantageous features.
Usually their shape is semicircular but various types exist, depending on their weight and form.
Their common feature is the near-symmetrical airfoil, thus forces necessary for returning do not divert them suddenly therefore they turn around at a wide sweep (world record is more than 150 meters).Lots of experience is necessary for throwing them.
