I relocated the antenna mount behind the servo. Now it doesn't get in the way when I need to remove the top deck. My first hole was too close to the top deck, though. So now I have another empty countersunk hole in my chassis. Doh!
I also played around with the steering linkage some more. Apparently I was wrong about tilting towards the top deck. It does seem to give more even throw with less EPA imbalance when it's closer to vertical with a slightly longer link. But I do need to double Check that my tie rods are even. I was centering the rack by eye.
I am still amazed by how light this car is.
