Smit Rotterdam motors
« on: April 23, 2025, 11:12:33 am »
Just ordered the Billing Smit Rotterdam kit.  It is twin screw with largish props.  I am not sure on what motors/battery to go for but looking at a pair of MFA 950D geared motors.  Should I go for 2.5:1. or 6:1 gear ratio?  Also I would usually go for a 2s or 3s lipo but would a 12v lead acid battery be better in this application?

If using 12 volts 555 motors direct drive will be fine.
