The diagram that shows how the servo is connected to the tie rods is hard to see. See the attachment below.

The screws don't interfere with the turns, but it is sure close. Seems like it should use shorter screws. And I can't tell whether the washer goes near the nut, between the plastic and the tie rod, or under the head of the screw. Anyone know?

I used short screws that fit tightly into the plastic of the horn; they were in the packet of hardware.

I didn't use any washers at all between the ball and the horn - the tie rod end moved freely on the ball.  But now that I think about it, a washer on the screw side to keep the tie rod end over the ball is probably not a bad idea.  When I assembled it, it looked like one side of the rod end was slightly smaller than the other, so that is the side I put towards the horn. The larger opening faces the screw's head.

I'd thought about doing some photos during assembly since I have all the equipment for making nice product shots but I was too excited and impatient to get it built to stop and set all the lighting up to do it... *sigh*

To further elaborate on David's response.  Engineering is allowed. ;-)

My various pictures, videos are only to serve as examples. There are lots of extra parts in the kit plus whatever you have in the tool shed.  It is all fair game.

That said, there did seem to be a particular order that worked better for the assembly and adjustment of the steering linkages than the others I tried... It took many more iterations of spinning the tie rod ends on than I expected to get servo horn standing vertical with the wheels pointing straight ahead.

ok. Thx. I suppose I could instead use the "sink" screws that are shorter. And just not use the washer and nut.
