I am looking for a way to slow down the winch when winding the line back up at the end of flying. Regis
On my winches I have a resistor control.... on my M50 winch it has three speeds.
The three speeds are achieved by using three solenoids, two have a dropping resistor
of differing values in series with them and one is wired direct to the motor.
This gives the three speeds. The full power can be turned off with a switch.
I normally rewind the winch at the end of the day on the lowest power, you can stop
the winch on this power by holding the line as it winds in.
This system has a couple of advantages over the foot pulsing system that seems
the norm in the States, it allows lighter models to be launched and you never have to
worry about the solenoids sticking on. I have been using the same solenoids in this winch
since the World championships in 1984 in Australia and their still going strong.
My latest winch has only two speeds which is better for launching the modern moulded
models.
If you would like any more info drop me an email.
