Set aft about 5-10 deg down, fore full down for a dive. You can use the forward planes to keep depth, but we’ve found it useful to use the negative tank as a regulator tank. When at depth, put 0.5 in the negative tank (halfway to the first mark, tiny bit) and that helps trim you too.
Historically the forward planes corrected small depth changes and the aft planes were used to correct small pitching tendencies.
Surfacing hard up on forward, 5-10 up on aft. Blow ballast when at periscope depth.
