The submarine is based on a Norbert Brugen ball fish hull, the hull is very hydrodynamic, you barely have to touch it to get it gliding through the water.

Its not getting hot as it's fine to touch and i'm not expecting to ever have it running that fast for long periods, and I figured being a high kv motor it would get warm. I know the mount needs improving as it wasn't straight enough and there's a large amount of wear on the coupling and was drawing 9amps at full speed (very short burst).
I have a new mount coming to replace my home made one which I think is a bit too flexible.
Edit for Wasyl's it's meant to be a fast moving sub, the slightest push and it really gets moving.
