RPM advice

[Neil]

Thanks mate, I’m totally confused now so somewhere between 150 to 300 RPM would be OK depending on the model size etc.
Could you ask the question “ has anyone built a 50:1 scale model of the Navy tug Fearless if so could they help me by advising The RPM for fixed scale twin paddles on this particular model ” is that possible please.

my recomend is 300\350 rpm, for a side wheeler,i run mine at about 50\75% full power, depending on the weather, if its windy, flat out.
stern wheelers are slower, but be carefull, too slow no thrust
you can always throttle back w speed control , but you cant get extra revs out of a motor\gear box.
i now try to use HTD belts, rather than MXL, who have sn
