Stu... the spur gear... I just thought you couldn't/didn't read the instructions!!
I've not done stand-up servo on my GT or Zen and not tried it. I used angled mounts on the original SS because it gave me the correct throw to the steering which I couldn't get from the lay-down servo position. Mark's GT cars are both lay-down, but he used stand-up on his SS.
Stand-up helps with initial turn in on 12th cars and was in universal use in the T-bar days (
here) but it doesn't work with the modern link cars. HTH
