Maiden voyage day today. Went to Setley Pond in the New Forest.
Found that on putting her in the water she had a slight list to starboard. This was cured using a Stanley Knife on the battery housing and moving the battery slightly to port,
The waterline was about right.
When running she is absolutely silent, no whines from anywhere.
The prop shafts I was having trouble with were no problem.
The motors only got very slightly warm.
Seemed to run at scale speed.
Ran for approx. 3 hours and still plenty of life in the battery.
Also kept all the water on the outside.
