drug sub has finally hit the water

Doing do-nuts in its own length.

At speed in a creek.

Cabin interior which is larger than a real drug sub.
This is the final post on the drug sub/ It worked as good as expected with a small problem of tracking, some work will have to be investigated on this and propeller pitch as it does as fast in idle as at top speed. The top photo shows it on the Shoalhaven river.
