Old Fart, whats the problem with brown snakes. We keep them as pets here, now Taipans that's a different matter. I will be doing some engine testing (with my mate) over the period between now and the new year. Bloody eye is proving a bit of an inhibitor but a good excuse when it comes to "stuff" that one is not enthusiastic about. We expect the ceramic bits in the new year until then the experiments revolve around fuel and props. Catch ya
