Hello:
Great work, the dive planes work great!!

I was able to go between 10m and 150 m with no problems (up and down, up and down). This only happens when I hit the crash dive button, then I can use the dive planes to move the sub up etc.
Is there anyway to manually control the amount of water entering and exiting the ballasts? I think we will need this control to really use the dive planes. In the example above, I cannot surface the boat with the dive planes alone, I need to hit the surface button. Likewise, I cannot submerge the sub with the dive planes alone. Is there any documentation for the dive planes?
At periscope depth, something unusual happens. No matter the speed or angle of the dive planes, I cannot go below 20m. See attached file.
