1) For some reason when I turn the Pershing tank's switch on, the switch on the turret on, the cannon fires continuously. Am I doing something wrong?

2) Is the main gun supposed to fire when I press the K button on the remote, or is that just to simulate recoil?

3) Is main gun elevation controllable only by pulling down on the stick and waiting for it to cycle from down to up and then up to down, so if I overshoot my elevation setting, I have to go through the full opposite first?

Thanks, and I am enjoying tank despite these questions.
