If the members don't want to support the Lists directly, then I might have to add advertisements to offset the costs of running the Lists. But I don't want to have to do that.

    Subject: Re: Autopilot Servos
    From: William Daniell <wdaniell.longport@gmail.com>
    Excellent thanks. Well as with everything else you change one thing and another challenge appears. The bridge i am putting over the rudder cables makes the turnbuckles for adjusting the cables impossible to get at/adjust. So I'll have to move them. One option would be to replace the cables with new, but before i do .... It there an approved method replacing the turnbuckle with some sort of non adjustable connection?
