I agree to use 550 motor with gear ratio 3+1 as one of choice for Banckert. I have a Banckert using the Kyosho high Torque Motor with gear ratio 5+1 to get satisify result.I play it in Cheung Chau Tung Wan beach and the tug boat can overcome the wave easily.However ,some senior modelboat builder recomended me to use Graupner high torque motor for direct drive without gear box. The model no of the Graupner motor is Speed 600BB Turbo 12V(No 3302). Using 7.2 Voltage battery for the motor to drive the tug boat.
Excellent high torque motors: Decaperm motors, very very hard to find and VERY VERY EXPENSIVE.
Graupner 600BB is the same as Mabuchi 545 motor with ball bearing.
Same current consumption as 550 motor.
It is always true that (motor+gear-box) is better than any high torque motor at the same cost.
