Well.........i did manage to get 3 position flaps using a 3 position switch, but i could only fine tune on flaps up & flaps all the way down. I know it can be done, 'cos i've done it once & it took me about 3 hours to figure it out, but i can't seem to duplicate the settings this time around. In the end, i settled for Jon-laser's method & even that took a little fiddling. Hey ho, thanks for your replies chaps.
Rob.
