I'm also interested in building a dual power python. My plan is NOT to have a rowing movement. So your right arm and left foot are pushing, while your left arm and right foot are pulling. It will be much easier if the hand and foot cranks positions are fixed and don't have a freewheel, because you want a freewheel that will only lock in one position, which you probably have to build yourself. A back pedal brake would be nice, to keep your response times short. I'm having this plan for quite a while now, hopefully you have more time. Looking forward to see your sketch Markus ============================================================ This is the Python Mailinglist //www.freelists.org/list/python Listmaster: Jürgen Mages jmages@xxxxxx To unsubscribe send an empty mail to python-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field. ============================================================
