Hi mad recumbent scientists ;-)
(I assume that this mailinglist is the most weird recumbent
hombuilder forum in the internet - but I love it)
Playing around with Ray´s app I got confirmed at least one
thing, that is noticeable in real life too:
The more weight is on the front wheel or pivot, the more
stable the python is when coasting.
Then we could just prolong the wheelbase!
I have another proposal:
Why not move the pivot about 20 cm towards the rear - that
means behind the seat.
High time to build an experimental scrap python - I will call
it PX.
Experiments sceduled so far:
- pivot angle of 60 deg and smallish negative trail
- pivot moved 20 cm backward
- rubber pivot
- four bar linkage pivot
Any other suggestions are welcome.
Cheers,
Jürgen.
