Rich, take a ball attach it to the line and time the time it takes to
travel the distance. Measure the distance then we can figure out feet/sec
The reason being that resistance and motor windings will make a
difference. Remember there are a few different motors out there.
And the new McCann winches at the Nats have a 2" drum.

Please read all the factors below before responding
For you math guys.
Lets take the NATS/ LSF winches as an example.
OK, first , line diameter may not be needed for this
calculation but drum diameter would be . Im not sure of that exact
drum diameter,,,,,,, ???? 3" ?
If using a three inch diameter , lets keep it constant. I know the
drum gets bigger when the line is stacked. But, you can figure it
both ways if your having a slow day.
The question is:
What is the maximum miles per hour that the winch will go pulling a 4
lb to a 6 lb model ?
One other factor Im giving you. Im not talking about launching using
the normal arc up over the turnaround. Im talking about a parrallel
to the ground, from winch toward the turnaround scenerio.
Thanks in advanced, Richard Burnoski
