Quoted from NightTrain:What's up with this game and airballs? I've never played another game in my life that has so many airballs. That damn thing flies everywhere. It's not just when the ball hits drop targets or stationary targets. It's simply when you flip the ball. The ball will leave the flipper bat and go airborne. I thought maybe it was the flipper rubbers for some reason. Swapped them out and got the same results.
Could it be that the holes in the playfield for the flipper shaft, are drilled in at an angle, causing a slightly upward motion when the flipper bat swings at the ball? I'm completely puzzled by this. I know I'm not the only one with crazy airballs.
Could be as simple as the positioning of the rubbers on the flipper bats. When you swapped them did you put them at the same height? They may be too high or too low making them launch the balls.
