Thats the same boat some of us have.

We have found that motor to be useless. I think theres 4-5 of us and nobody is running that motor anymore...

I ran mine with 60 Amp esc and 3S lipo. Running just a single 20C pack wasnt good...

beware of foul language...

Its a good boat but that motor is just to small for it, thats the bottom line. For $120 its a good buy. I would sell the ESC off for about $45 and the Motor for $15-20 and then you got a prebuilt boat minus electronics.

Thats why I bought it also. I wasnt sure how to set the boat up and didnt want to risk messing a hull up.
