I fixed the problem now. I had not set any waypoints to the target, so although it started off at the initial correct speed, it was slowing down all the time. By adding a waypoint with a speed, the target behaves as expected. Now I am having 100% hit rate with my whizz wheel.

The only problem now is that I am unable to use the whizz wheel with none zero gyro angles. I guess this is because the gyro angle doesn't kick in until after a few hundred yards, and therefore the actual angle to the target from the periscope is slightly different to the gryo angle.

Does anyone know what the exact distance is the torpedo travels before the gyro angle preset kicks in?
