Power drain - what am I using.
I've always built model boats by installing electric components which seemed sensible, rather than measuring or carefully planning the components. I've now (belatedly) decided to measure what I've created, with a view to determining the actual power consumption and potential endurance.
Consumption figures for each model are below.
