Gday Dubbers, anyone know of any good sites that have plans/good diagrams for trike frames and leading link frontends?

cheers

Look up "Three Wheelers Club" then try and talk to a guy named "Gert" this bloke is brilliant and will steer you in the right direction, both mechanically & Legally cheers Frank

If you're building one from scratch the critical measurements are the angle of the forks and the distance from the front to rear wheels.

That will make or break it.
My old man has one the German made/imported bontrikes and there was forever people building their own coming to measure it up.

Most people make the forks too steep and end up with something that doesnt want to turn well or is unstable at speeds.

When set up right they are the most awesome experience you can have on wheels, not even most road bikes can out corner them.
