I am a confirmed fan of Arnaud & Khamsin's creations and look forward to purchasing their DHC1 Chipmunk. I love classic, tail-draggers and hope that they will find time to build others like the DH Tiger Moth - maybe even an Auster or two? (special favourite because I learned to fly in that type!). Please, please put my mind at rest and confirm that the Chipmunk will be compatible with X-Plane 9 - I have looked at the XP10 demo and find that it will not run on my iMac 20", even at the lowest resolution and weather settings! Aargh!! They call it progress! I have resigned myself to the fact that I shall only be able to fly aircraft which make small demands on my 256 MB graphics,( which cannot be upgraded on the iMac), so I shall be especially delighted to have this beautiful aircraft at my disposal. Can't wait! Autocrat
