… n load Max efficiency probably around 60% or less. A 1000kV brushless will have an efficiency more like 80%, thus draw less current for similar performance as the 600 but still have power in reserve, do 11100 rpm or more off load on a 3S Li …

… 00 to 21500 So which spec to use as a basis for choice of a brushless??? My choice would be a pair of 750 to 1000kV brushless. Prop size significantly affects current drain and speed. Often a bigger prop simply sucks more current with no pe …

Fully agree Haig My results converting the Sea Scout to brushless (1000kV) were very similar to yours. I junked the old 2 blade 40mm prop and Decaperm, put in a 1000kV brushless and a 30mm 3 blade prop and she now goes like stink (plenty of …

I have both Brushed and Brushless motors in my patrol boats and MTBs. I was somewhat misled by the catalogues quoting large Amp ratings and power outputs of the brushless motors. What I did was to mount an on-board video camera to focus on …

The other advantage of brushless that I forgot to mention is that the combined current draw of your two brushed motors will less that 10A. The two brushess will exceed 30A. This makes battery life much better with brushed and also fusing si …

… question though. The plans state two 600 brushed motors or brushless of similar level. Please can you tell me, say at 11.1 volts, which brushless might be similar but a little faster. Thanks. Peter.

Well Peter, I have tried both brushless motors, and without a doubt, I always use Inrunners, in all kinds of vessel, they are the easiest motors to water cool, straight from the inlet, to the motor then into the ESC, and then out, dead simp …

In some respects you can think of a brushless motor as part way between a standard brushed electric motor and an I/C engine. The brushless can turn on and off like the electric motor, and is clean like the electric motor. It has a high powe …
