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
