Didn't know Amps were directly related to boat length.... you learn something new everyday.

Andyn:
How didn't you know this previously?


Boat legnth divided by rudder legnth times lake depth minus boater height equals speed controller rating.  %)

Andyn:
I see what they're getting at, typically a fast boat of X size will have X motor, which requires X esc. Doesn't really translate well though...

malcolmfrary:
In the elder days, motors were always sold as being suitable for boats of a given length.  Oddly, probably because of the limited types of boat possible and the limited types of battery available, it worked.  HK are assumng that there is only one type of model boat that needs electric power.  Unlike earlier times, the only type is now fast.
Might be time to revive the link to the uses of the multimeter.
