Album Info:
Tuning and airfoil carving are the two most crucial factors in flight performance . Blunt leading edges - slower spin and speed , sharper sleeker edges gives too fast a spin, you want it just right . Trailing edges create lift . Diffrences of 1/16th an inch make big diffreces in flight . Order John Cross's book on boomerang making .About $20 .
