Looks like he is learning fast. As Bill mentioned real tanks go very slow in reverse. It is unrealistic, but our RC tanks go just as fast in reverse since we can change the direction of the motor is spinning in instateously. Real tank engines do not have that option. Planetary gears provide them with a slow speed but high torque reverse. So we are just as fast in reverse as forward. Oddball from "Kelly Heroes" would be proud. Woof Woof!!! ....LOL The reason I mention the reverse driving practice is just as Bill reiterated. Keep you gun pointed towards your enemy at all times. It will make him think twice about taking a shot at you if is staring down your barrel. As his driving improves move him further away from the tank. Don't let him follow it around but have him drive it from where he is standing.

Good luck, Bob
