On the other thread you said something about manufactures keeping information secret. Tilting Motor Works is one that is very secret. I was told that when a customer places an order they must sign a "No Disclose" statement.

Stuart Mills of the English MEV fame designed a fair one but sold it's design and rights over to a US corp.

To design in a well working tilt you must make the chassis heaviest* at 0 degrees centered so it will always try to stay centered upright. Then as you turn and apply tilt it must lift the chassis up and out of center, on the outside of the turn. When completing the turn it all needs to "SELF" return back to 0 degrees centered.

*The term "Heaviest" does not always mean true weight, it could be spring tension or hydraulic pressure.

Take 100 pounds and put a 300 pound draw spring on it and try to lift it, its 400 pounds heavy but only 101 pounds mass.

I have ideas of using my legs to apply tilt sort of like the rudder controls of a Airplane. In my trike build I will not have any transmission gears to shift and no clutch lever or pedal. My right hand will control the throttle and my left hand just the brakes by lever.

The tilting mechanism I have designed for my trike will use an offset lever in a slide slot to make it heel over to about a maxium of 40 degrees each way.

I am probably going to use a hydraulic motor to do the tilting or a geared electric stepper motor.

The geared electric spepper motor would give me the best control over it and some of the larger steppers with planitary gears should be storng enough to do the job.
