Well I give up, I can't get the main gun or the machine gun to fire. I installed the battle unit stuff, plugged in the apple
(and read the warning about unplugging the apple with power on) and still nothing.
The directions claim that I should be able to move the steering stick to the extreme right and the gun should fire, or to the extreme left and the machine gun will fire.
I will bring the thing to Danville and hopefully with some help get the thing to work, Who knows I may have a Sherman for sale and stick with airplanes!
