I'm not sure I understand the south vs the north. Wind direction I
understand, compass direction without wind direction I don't
I stand by what I said. I believe that for the FLS a 1.75 to a 2" drum
to have more power than the 2.5 to 3" Goughner. Think of the drum as a
transmission. If you start out with a big drum it is harder to get
going, and you keep going up in gears (line makes the drum bigger) so
you have more speed but less torque at the end. Too much speed that you
can't get the FLS to move it stalls.
With a smaller drum 1.75 to 2" you have the optimal power to speed. At
the start you are getting good torque, at the end you are still getting
good torque and speed since the line has added and you are still able to
turn the motor.
In F3B we mostly rely on the line stretch for Zoom... in USA TD we rely
only on the motor. So a smaller drum equals more power.
One of my clubs replaced there winches and drums but not the motor. They
went to a McCann winch and drum.. The power went up. Why? The drum
diameter decreased from there previous drum.. The frame didn't do anything.

With all due respect I disagree Jeff.
At our local field when we launch to the north, it takes all the line
off the drum.. We get much softer, less powerful launches.. As opposed
to when we launch to the south we still have approximately half the
winch line left on the drum at the time of launch and the launches are
much more aggressive/powerful and all the broken lines and broken
models come at the south side.. Just My observations here in
Tullahoma.. Brian Smith

Charlie less drum diameter will lead to more line breaks. Since you
have more torque you can now crank more turns in and break the line
easier. -- Jeff Steifel
