The first modification is a good F/C trainer. This variation maintains a circular
orbit, curving inward and slowing down at the end of the flight while retaining a
high rate of spin with a low altitude hover. No airfoil modifications are required.
#2 The second planform shown is called the Enduro.
This boomerang is very stable with a very predictable flight path and a constant
deceleration. This is obviously Eric's choice for Endurance.
#3 The fastest model is depicted as planform #3. This design is less forgiving
and should be used for your second round of F/C for a shot at first place.
This is a great boomerang for setting a personal best round.
#4 is Eric's best design for the Accuracy event. This one just dies at the end
with a stable drop.
#5 is Eric's best equipment for his specialty: High Wind Fast Catch.
This model is very stable and exhibits excellent loss of spin at the end .
with a drop into your lap.
#6 is the planform used by Gregory Bisiaux when he set his Fast Catch
World Record at 15.03 seconds. (clic here to download the video of this record )
It is not known what subtle modificationsGregory made to the airfoils, but the
material was Polypropylene.This was a surprise to Eric as well, because the
intended use for this modification was for an inside doubler.
The outside doubler is an unmodified tri-Fly.
#7 is a Fast Catch made out of ABS. It is almost the same as the Enduro,
except for a narrower chord and a true airfoil with a trailing edge added to speed
it up. Designs 1-6 do not have modified airfoils. Eric says to just leave them blunt.
#8 is called Soft Toss. This is a very easy boomerang to throw.
It is also good for Consecutive Catch, especially for the over hand catch.
This model also has a strong trailing edge.
