Hi Ian
Dave's right I have only used the Hobbyking car ESC's (HK-30A, HK-45A, HK-60A SL and HK-100A) because the club members use them .
Same program card for all (PROG-CARD).
Same set for all boats(except for the different batteries).
Plug into radios like a servo and no setting up.
Small and light (maximum 106 grams), electric fan for cooling and no plumbing for water.
The only thing is they only handle up to 4S Lipo batteries and 100 Amps.
So I do have a few water cooled ones for higher power and voltage.
Our ESC set up for boats
1 Cutoff Voltage for 3S=10.2 and 4S=13.6
2 Start Power Percent=10%
3 Advance Timing=4
4 Run Mode=2
5 Brake Force=1
6 Drag Brake Force=1
7 Neutral Range=1
8 Initial Brake Force=1
9 Reverse Force=1
