Dear All Numerous people from this list have contacted me individually asking for more info about the auto pulley launch system that we have been working on in Western Australia. I decided that it would be very beneficial if all the knowledge related to this form of launching could be shared in a group forum and many pilots have indicated that once it has been set up they will join. I also anticipate that I will get those with much more experience than me on this method as well as veterens of winching, auto launching and other interested glider pilots.
I decided on yahoogroups for at least the following reasons: -email forum that automatically distributes messages -searchable email archives -members can post files/links/photos for others to view -many idividual and custom settings. The new forum is at: http://groups.yahoo.com/group/pulleylaunch/ and is easy to join (pls email me if you have any difficulties joining or using this group). Please feel free to join and do not be shy to contribute: -emails -links -photos -files or whatever I have written a description on the home page which compares auto pulley launching to winching although I do think winching is still a great way to get airborne. Here it is: 'A forum to exchange information on the method of launching sailplanes and other soaring craft via the use of motor vehicles pulleys and rope/wire. The advantages over winching include: -requires less equipment to be constructed -requires less facilities to store the equipment from the weather and theft -requires less maintenance -requires less labour (ie with 1:1 the rope is automatically relaid) -can get gliders launched much quicker than even a double drum winch (max of 120 launches to 2,000 feet in one day) -requires less operator skill -better comfort for the operator -no problems and lost time due to tangles -less downtime due to equipment breakdown -alternative vehicles usually available in case of breakdown -R & D is done for free by the MV industry (they spend billions each year !) -no need to transport and store fuel at the airfield -gives a smoother launch with better tension control -better safety record -etc etc etc 1:1 and 2:1 have long and excellent operating history in the sport while 3:1 has been demonstrated with proven benefits and offers much promise.'
