Step 11
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.
The cell slots in the chassis are designed to fit the
cells properly if you just knock off the sharp edges. If
you bevel the cell slots the batteries will hang below
the bottom of the chassis.
Special note:
Carbon fiber dust is really bad for you. Always
wear a mask and eye protection when sanding or
filing carbon fiber.
Step 12
Step 13
Attach the two flex plate assemblies to the real lower
pod plate with 4-40 x 1-4: flat head screws.
Temporarily remove the 10-32 set screws in the flex
plates in order to access the 3/32” hex in the top of
the pivot ball so you can tighten it down firmly.
Replace the 10-32 set screw and adjust it so there is
no play between the pivot ball and the pivot ball
housing on the flex plate. However, the flex plate
must still move freely. If you lift the front of the flex
plate, it should fall under its own weight when you let
it go.
Locate 2 gray anodized non-threaded spacers, 2
gray anodized threaded spacers and 2 4-
40 x ¼” flat
head screws.
1.Pass a 4- 40 x ¼” flat head screw through the hole
in the chassis corresponding to the front hole on the
flex plate.
2.Thread the gray threaded spacer onto the screw
and hold it with needle nose pliers as you tighten the
screw.
3.Repeat to assemble the other side
