Obviously hydraulic pistons were just a lead in to my silly visual of
Mexican Low-rider-like bouncing pythons :-D This is were communication
through the web isn't so good as you couldn't see the big grin I had going.
A lever-like linkage would work. The pivot angle movement required is not
much (5-10deg) and a longer lever (advantaged like a pry bar) would make the
actuation force minimal. The pivot (with rod ends) could be sandwiched
between rigid side plates on a horizontal cross shaft with bearings and the
rod/lever could act through the side of the plate with a "U" catch for the
high (cruise) & low (fast) positions.
On the other hand I do have a 115db Airzound horn which uses a
water-bottle-like compressed air bottle at 100psi!! Perhaps pneumatic
pistons could be made to work.
Daryl - off to put on some "Los Lobos" and think about it ;-D <----note,

Hello listees
Perhaps Daryl's whacky thought has some merit. But, rather than using
hydraulic pistons or some such,how about linking the pivot angle to the
seat. By that I mean have a seat with a recline angle and or height which
could be changed on the fly. As the saet recline was raised- for increased
stability the pivot angle would also change in the direction which would
give better stability. Seat connect by mechanical linkage to the pivot.
Would the extra complexity and weight penalty be worth the variable stability?
