Condensed Know-HowÂ (for more detailed information, cf. our ld book
We compiled a few hints derived from other throwers and based upon our own knowledge regarding the tuning of LD boomerangs (aoa = angle of attack):
- Adding a positive dihedral generally results in a higher and shorter flightpath with the boom
having a larger laydown rate, and you risk of obtaining a screw* flight pattern.
- With a negative dihedral on the other hand you obtain a boom that flies fa,rther and stays
lower. Besides, the laydown rate is smaller, so the boomerang flies a more circular, left** flight
- A positive aoa on the leading arm gives more drag and provokes a shorter, more circular
flightpath with less laydown. A negative aoa lets the boom travel out straight farther.
- Adding a positive aoa at the dingle wing renders a more circular flightpath with a hover at the
end. With a negative aoa you obtain a more elliptical flightpath and provoke the boom to perform an s-curve on its way back.
REMEMBER: Be careful with your tuning. Make only small changes!
flightpath: boomerang (right-handed) precesses to fast and keels over to the right
flightpath: opposite from screw
, boomerang does not precess (tilt axis of rotation) sufficiently, it makes a large curve to the left and always lands left, no matter how flat you throw.
