RE: Aquacraft Hammer with Brushless 8L motor
I am also concerned with two things here.
1 - Battery! 12C, 3600mAh @ 80% is only 35A
2 - This is a submerged drive, not surface. I believe a 40mm or even a 37mm is way too big. Start small and work your way up. Don't start with disaster.
Neil - You can keep the amps down by using more cells and dropping/decreasing the size of prop used.
