Here's another reference. It's taken from a book I've got called "Tune to Win" by Carroll Smith (ISBN 0-85045-808-0). It's about race car tuning but covers the...
IMO one of the best books by Ortega is "Meditations on Technology" written,I think in 1920. Amazingly his predictions still apply. I have been saying for years...

Whoops, quick correction, I got my deltas and tadpoles mixed up. Last post should have read: "If it's a delta trike this will be at the rear and so the vehicle...
... Hi Dave... possibly. I HAVE said that for any GIVEN TILT ANGLE a load transfer tilter can generate greater cornering force than one that does not...
... Gosh, I've never seen a book that ignores the effect of weight and air pressure on the size of the contact patch before. Has Carroll never pumped up a...
... Phillip here.... yes Bob... the bleeding obvious seems to be ignored.... or the context is being stretched out of its box. Maybe in a F1 racing tyre at...
... One of the sillier things I've seen is a tilter with a wing that does increase side force as well as down force. i suppose we could articulate things to...
... It could be that he is quoting "for a given air pressure and weight". The results of his work have been faster racers, so even if his science is wrong, the...
... Yes, at speed, with load transfer, you would be better off with anti- ackerman steering. Maybe that's why racers like to hang the back end out- it may...
... As I understand it max traction is achieved at between 10% and 20% slip. Road racers routinely operate in this region. Dirt bikes with much higher slip...
snip ... ISTR some go-karts having anti Ackermann steering geometry, but I could be wrong about that. What I did find when driving a friend's racing kart was...
... Oh, I though we were on about the fellow who seems to inflate his tires with water, so that the contact patch stays constant with changing load. Best, Bob...
Actually, scratch the increased slip angle benefit from load transfer. Since the load is transferring TO one laterally opposed wheel FROM the other, then the...

Hi, I have a new sketch (under photos, 1F2R #A) of a rearranged setup of what I now have. The changes are (1) the swing arms are mounted at the front of the...
Hi Don, My opinion is that what you are proposing in that sketch is not a good solution. You are going too far in the opposite direction and giving your front...
Hi Dave, Is not the proof in the pudding. The contact patch center, when the wheel is steered, moves in a circular path with a radius of 14" curved forward...
