Congrats on your first Tamiya. You'll have a great time building from the ground up. One other little tip is to sand off 2-3mm from the bottom of the mantlet to get more depression, also I've found it
easier for maintenance to move the power switch to the rear of the lower hull (running the stock wires over the speaker)rather than having it in the turret. Just makes it one less thing to worry about when your taking the upper hull/turret off.
