Besides the external camera, there are three ways to determine if your batteries are charging.
Click on the CE/Propulsion. The current propulsion mode is highlighted.
Look at the RPM gauge. The right engine is used for charging. If it is charging, the RPM is at the maximum. If you're at flank speed you won't see a difference, but if you slow down for a moment, you will.
If the green light above the engine telegraph is on, the engine is turning the propeler, and not charging the batteries. Unfortunately that feature doesn't work for all types. I'm certain that it works with Type VII, and doesn't work with IX.
@everyone
Is there a fix for this issue?
