Step 12
Locate the delrin center pivot assembly, one 4-40 x
¼”, and two 4-40 x 3/8” flat head screws.
Attach the center pivot assembly to the rear most hole
in the center of the lower chassis plate with the ¼”
screw. The shoulder on the pivot ball and the two
bosses on the center pivot assembly should face
down towards the chassis. The pivot ball has a 3/32”
hex in the top so you can use a wrench to tighten it
firmly.
Attach the rear lower pod plate to the center pivot
assembly with two 4-40 x 3/8” flat head screws.
Take a minute to prepare all your carbon components
for assembly. With a file or sand paper knock off any
sharp edges along the perimeter or the carbon parts.
Special note:
Carbon fiber dust is really bad for you. Always
wear a mask and eye protection when sanding or
filing carbon fiber.

Step 14
Attach the two flex plate assemblies to the lower pod
plate with 4-40 x 1/4: flat head screws. Access the
3/32” hex in the top of the pivot ball so you can tighten
it down firmly.
Locate 2 copper anodized non-threaded spacers, 2
copper anodized aluminum lock nuts and 2 4-40 x
½” flat head screws.
1.Pass a 4-40 x ½” flat head screw through the hole
in the chassis corresponding to the front hole on the
flex plate.
2.Pass a copper non-threaded spacer over the
screw.
3.Slide the forward hole on the flex plate over the
screw and the spacer.
4.Thread the aluminum locknut onto the screw and
hold it with a 3/16 nut driver as you tighten the
screw. You want these nuts to be tight but do not
overdo it. You do not want to strip the nuts.
5.Repeat to assemble the other side
