Gill will this esc be better than the t180 as its only 130a continuous & burst 180a, not sure what difference the HV makes on these though over the 180a do you know at all. If your looking to push a bit further in future OSE, Offshore Electrics have a custom wound Leopard 4082 - 2200kv which is also a y wind motor. I dont know if you are aware but their are boat specific Leopard motors that are different inside the motor & they have slotted end caps for better cooling. The internal changes are only on the 40 series motors, all the other series motors ie 28 series,36, & 56 are all the same inside with no boat specific motor. All the 40series boat motor have more magnets than the car motors (car versions have the wires coming out of the side of the can at 90 degrees & solid end caps. The motors with more magnets are said to give more torque. This info was given to me by Leopard factory tech department when i spoke to them. Im still deciding what Leopard motor to go with for mine.
