Setting the servo aside for a moment, it’s time to make the small drag link (ASC
9170) which connects the servo to the bellcrank system. Find the two small ball
cups and the threaded rod. We recommend pre-tapping the two ball cups with a
normal 4-40 screw to make installing the threaded rod easier, but don’t let the
gorilla over-do things.
I6)
Using some pliers to hold on to the threaded rod, screw one of the ball cups
around half-way on. Screw the other small ball cup onto the other half of the
threaded rod, and tighten it down toward the other. You’ll want to orient the ball
cups so they are 1/6
th
of a rotation from parallel; that is, the flats of each ball cup
line up together, but the cups are one flat from being lined up. The overall length
of the drag link (outside to outside) should be just over one inch (25.4 mm).
17)
This step is easier with the servo out: pop one
of the steering link ball cups on the left
bellcrank/servo saver inside the car. We show
the servo in the forward mount, so the drag link
is oriented with the other cup facing the front of
the car. If you’ll be using the rear servo mount
holes, the cup faces back.
