Thanks for the replies on and off list. Thanks Peter Henderson. Bob Ward, my work PC is not subscribed to the Aus-Soaring mailing list. I think Foresters and Outbacks are great, would'nt mind one myself. Those who have time for a chuckle or a serious look at the issue, see: http://poseur.4x4.

Several possible directions in safe, reliable, cost-effective "tug technology" appear to have promise: 1. GA aircraft (including ag aircraft such as our good old Pawnees) with efficient low-maintenance engines - eg automotive-based, diesel, turbo-prop. 2. "Ultralights" with suitable powerplants -

Jason Sounds like you troops haven't ever heard of Univair in the US? And parts they make under FAA PMA approvals & STC'd kits of parts for the PA25-150 and PA25-235, -260. You can get most everything you need that is of special nature for the Pawnee structure from Univair. The rest is standard

Miles, I kept in touch with Benalla re the state of play, and had a request with Gary to keep me updated as to the likelyhood of a viable 18 M class. Additionally, it has been very likely for the last couple of weeks that the fires would be the final nail. Unfortunately, that has come to pass. Rega
