I take out the return spring on the winch control lever, and set it so that when the lever is pushed away from me, the sail winches in (goes faster) and vice versa for pulling the lever back. This also means that you can set the sails at any position and let go of the lever.

Hope this helps

Down for in and up for out, a boat goes faster on a broad reach, thats about half way.Most racing boat skippers set up the winch like this.

Hello
With the TX stick fully back towards you, the sails should be pulled right in.
Make VERY sure that the Winch is NOT stalled, in this position, it is possible to set things up wrongly and have the Winch pulling against the sails and overheat it and run the batteries down.
Model yachts don't sail much with their sails pulled hard in, so I set mine with the TX trim set to full in on the winch and sail with the trim in the mid position.
If the stick is set up WITH the trim set full in, there is no way to stall the winch while sailing.
Easier to do than explain !!!.

Your set up may be different.
I am using a futaba sail winch and futaba attack two Tx

With the TX full back, and with the trim full back my sails are set at about 10-15 degrees from the centre line of the boat. Which is as far in as I want them. Compl;etely in and the boat is going nowhere. With my set up, full out (85-90 degrees) is achieved with stick and the trim fully forward.

I don't have ratchet fitting on my tx lever, but by using the stick and the trim I have 6 basic sail settings anyhow.
The wind changes so quickly where I am it is pointless try to 'set' the sails for more than 5 meters. ::)
