J250 BLACK MAX RELOAD
Black Jack‰ã¢ (J) and Black Max‰ã¢ (FJ)
Provides the high visibility tracking of dense black exhaust. In addition to a distinctive
lift off roar, Black Jack motors give your models lower acceleration and longer powered
flight than White Lightning or Blue Thunder motors of the same total impulse. Black
Max provides slightly higher acceleration than White Lightning Propellant.
I have used this motor over a dozen times. It works flawlessly every time with dense black/grey smoke. It is one of my favorite motors. Great job Aerotech!
