Motor and esc

[Old Vetter]

Has anyone tried to run the AquaCraft 36-56-2030kv motor with the ProBoat 45 amp ESC on 4s? The esc is rated at 45 amps and the motor is rated at 50 amps. Think it will work or will I smoke the esc?

It does not matter what the motor is "rated" at, the amp draw depends on the prop used. I race that motor in my FE-30 hydro and routinely pull 80+ amps without hurting the motor. OTOH I doubt that the PB45 ESC would like that amount of amperage. You use the 2030 Kv motor to go fas - if you keep the amps down to under 60 then you won't be so fast.....

Thanks for the reply Fluid. Sounds like the AquaCraft 65 amp esc might be a little marginal itself. The motor is going into a Dumas tunnelhull that has a ProBoat 45 esc and the 1500kv ProBoat motor. I would like to have a motor with a little more kv because I am limited to a small prop with the REK drive unit.

I run a 29" OPC tunnel with the aquacraft 2030kv motor and the aqucraft 60A ESC on 4S1P, m440 prop for sport running and it works great (another guy I race with uses the same motor/esc config). I have propped up to x442 and the caps will get pretty warm but ok for racing with enough cooldown between runs. Even with the bigger prop, the ESC itself is pretty cool- just hot caps... I once ran a seaking 120A in that same boat and I still blew out the caps, so bigger ESC does not necc solve the hot cap problem. Fluid advised me to shorten the esc battery leads and that really helped.

I also am running a 1/10 scale shovelnose with a proboat 1500kv motor and a proboat 60A ESC and the ESC and caps on that config are cool with an x445 prop.

You'll pop the 45a with that motor............
