Fair comment tacpot, my Auster fits all the performance figures you list and is loads of fun as well. It would actually be cheaper for me to run the Argus as part of a 4 person group than continue to run the Auster by myself, unfortunately, nobody, apart from FNG it seems, is in a position to do so. I'll just have to stick to Austering for the summer then
Ah well, when the Government taxes 100LL at the same level as Avtur private flying will increase. Oh look, there's a squadron of pigs in the car park. Fully fed and ready to fly
