Using a single servo horn with 2 ball connectors is not exactly the same... (tried it...)
First of all when turning the distance between the 2 ball connectors is reduced (not the actual distance but as per the moving axis) and this can produce ackerman.
Also the length of the turnbuckles is not the same so there is a chance to have different max angle on each side.

Very nice idea and very well executed! :)

Very cool setup and very cool servo. I don't know if it is the camera angle, or maybe the caster angle, but it doesn't look like zero ackerman as your outside wheel looks like it turns sharper than the inside wheel. Sero ackerman geometry is achieved when the turnbuckkle ballstuds are the same distance from each other as the steering block king pins. Tie rod & steering bridge geometry wil affect this as well. Again, it could just be the camera angle though. But very cool none the less :up:
