Circling? Sweet.

Shaun, this is all Spektrum DSM hard wired into the chip. I have a few Futaba 75mhz systems that I'll use when I try this for real, but for now the 2.4 is fine. I wasn't planning on really going deeper than periscope depth, which 2.4 reaches. It's just the lack of driver skills to keep it going straight once it skimmed below the surface instead of continuing on an arc down.

We built an old Lindberg destroyer as RC with sound, etc and put the sub together as a target.
