I've always have been intrigued by reverse & delta trikes. Lots of aero advantages and lightweight platforms. Unfortunately Carver, just declared bankruptcy, but the Morgans are back. You've built a few already and you know the need to locate the vehicle's CG to keep the wheels on the ground, especially during quick handling maneuvers. Is it a passive steering mechanism or do you have active lean/tilt steering? Interested in the geometry.
