Hi I'm here asking a question about the pivot angle. I'm bulting a trike like baccura http://kb7mxu2.home.mindspring.com/images/baccura.jpg in that case, with 2 point linking front frame + seat (single block) TO rear frame, 1. about 63-65° of the pivot near front wheel are still significant to self centering effect? 2. well.. here it still exist a self centering effect (I mean, with a couple of connection between the 2 frames?) 3. the seat should be lower than the front wheel axle? Or the point to self centering effect still remain the pivot angle? I know.. that questions are beyond pyhon design, but they concern the world of recumbent anyway! many thanks Matteo ============================================================ This is the Python Mailinglist //www.freelists.org/list/python Listmaster: Jurgen Mages jmages@xxxxxx To unsubscribe send an empty mail to python-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field. ============================================================
