    Default What motor can I use with a 90 am esc and 4s battery?

    Hello

    I have a Blackjack 24. Trying to get it to run 35 to 40 mph. I have upgraded the esc to a dynamite 90 amp. It still have the stock 2000 kv motor.

    I want to get it faster 35 to 40 mph. How can I get it faster with the 90 amp esc? Is there a motor that will run on that esc and 4s and fit in this boat?

    I attempted to install a new dynamite motor, the 1750 kv 4 pole. But it is simply too large to fit under the cowl so I guess I need a smaller motor but one that can handle a 4s?

    2000kv is a good rating for 4s, I would use the stock one.

    Thank you for your response. On the Horizon Hobby website it only lists it up to 3s so I was not sure about running a 4s on it. All I know is it is 4 pole 2000 kv.

    I just purchased a 2750 KV Leapard motor with water jacket from OSE. I saw a guy online use that motor so I thought I would try. It says it will run 4s online on one site.

    Do you think it will work? I have a 90 amp dynamite esc.

    Do you think I will have to program ESC or will it bind pretty well?

    Any other tips are appreciated.
