Hello pythonists, I've managed to take some specs from my python. I decided to take high / low measurement where possible. http://www.nojapyorafoorumi.fi/viewtopic.php?f=18&t=1437&start=45 quite bottom of the page. I hope that it's ok to use that Jurgen's drawing? And that there isn't already a python named PPPython? And having a videoclip from practising and cruising. No big bruises :) http://moment.pic.fi/kuvat/nikonisti/Videot/ 2010/7/31 david hout <bmwmadman@xxxxxxxxx> > im still learning to ride mine. i dont have a trike to play with. im trying > to work out a set of training wheels that can be unbolted later but have not > had time. its very frustrating to not be able to ride the bike i built. > > Reality is merely an illusion, albeit a very persistent one.
