Using a hobby knife, or Dremel tool, trim the plastic pivots [1] as shown. This
gives added motor and battery clearance.
Assemble the Center Pivot assembly as shown in Figure 2. Tighten the 2-56
flat heads [2] enough to remove any up and down play, be sure the flanged
pivot ball [4] pivots freely.

1 - Place the 4-40 x 3/8” screws [5] through the graphite chassis [6] in
the holes shown. Tighten a 4-40 thin hex nut [7] down fairly tight.
2 - Then, after both thin hex nuts are tight on the 2 mounting screws,
drop the assembled pivot plate over the screw posts.
3 - Drop a washer [8] over each screw above the pivot plate assembly.
4 - Thread on the 4-40 red locknuts [9]. Do not tighten them yet as we
will adjust this later.
