Hi every body
I’m taking part in an rc model boat competition. I’ve made a catamaran hull which is 1300 mm long, 500 mm wide, 150 mm high and the overall weight of the boat is 15 kgs. The boat has 2 propellers both of which have 45 mm diameter and 50 mm pitch. I am using 5 LiPo batteries each are 3.7 V and 5 Ah. The specifications of the motor are as follows:
XM3548CA, 6 turns, 720 RPM/V, Max efficiency current is 25 Amps, the Max power is 650 W (15s for the mentioned batteries), Max efficiency is 80%.
According to these informations what gear ratio should I use?
:confused: :confused: :confused:
Thanks alot.
