This was my third uboat it is really easy to start and dive. You do not HAVE to turn on the electric motors while underwater but for maximum realty you should. Torpedo tubes work like this. Flood the torpedo tube till the light turns on, Than hold the crankshaft till it shows the door is open or until you hear a clank. Than go up onto the attack parascope (In the conning tower) look to your right select that tube and hold fire!
