RE: Aquacraft Hammer with Brushless 8L motor
i think your prop will be the most problematic part of this.
the prop is to big. You should try a small prop like a octura series X427-X432 for starters, and work your way up. you don't want to over amp it and burn it up.
I personally would start with those props mentioned
also with your esc, the motor will cog on start up probably quite a bit.
