There is still a lot to find put on how it works.
I can copy his design and ad tank steering and that will solve the steering problem and ride like his trike. But I don't know if his trike was good or because of the small steering angles and the amount of tilting, that it wouldn't mater that much and that the wheels wringing in the corners, was limited by the size of the tires he used.
For what I see now, is that as I make the lower arms shorter, the inner wheel tilts more than the outer wheel, what makes that he compensated that way for the lack of ackerman.
It also resulted that the tires would wear a bit faster, because the distance between the wheels where they tough the ground, becomes smaller.
Not much, but it gives some friction.
I don't think that it is a big problem and lesser of a problem than the friction that you have in a corner on a normal trike.
There is a lot to look into.
I think with changing the bottom arm lengths, that I can remove the ackerman setup.
Those balljoints us something I was looking for.
As I make that you need to tilt, to steer, than they aren't needed. But as you make that you can ride it as a normal trike and a tilt trike, those are sertenly needed ad the linking system of the wheels. Only because of that the angle of steering whyle tilting is way less and with the way I mounted them, they rotate enough.
I will look and test tomorrow more.
I noticed that ad an angle of about 30 degrees tilt, the inner wheel, tilts almost 3 degrees more.
I will see what te difference will be with shorter arms ad the bottom.
It is not jyst a system that you can put on a trike and it works. I understand why you needed to tune it each time. It is a system that changes in every angle.
