1 - In Bag 2, find the graphite bottom plate [10].
Secure it to the center pivot assembly with the
½” red flat head screw [11]. Secure it tight with
the red 7/8” hex standoff [15].
2 - Find the 4 red low profile balls [12]. Secure
them as shown with the steel 5/16” screws [13].
3 - Locate the plastic side links [14]. Inspect the
links and you will notice that the screw holes on
one side of the link are larger than the holes on
the other side. Before popping the links on the
balls [12], be sure that the larger hole faces
toward the outside of the chassis.
4 - Slide the 2-56 button head screws [4]
through the large holes in the outside of the side
links, and then thread them into the small inner
holes as shown in the illustration. Do not tighten
these screws down all the way. Put just enough
tension on them so that there is no play in the
links, but so they pivot freely on the balls. The
car will NOT handle properly if the links are too
tight on the balls.
1 - Be sure the 2 aluminum locknuts on top of the center pivot are slightly loose.
There should be a washer under each alum locknut. Notice that the center pivot
“floats" or moves slightly on the 2 screws. This "floating" allows the links
to "free up". This ensures that the rear pod plate pivots freely on the links
and center pivot ball. This is a crucial step when setting up the Battle Axe.
2 - Snap the 2 links on the balls (done in previous step). They should rock freely on
the pivot balls.
3 - Place the chassis/backplate on a flat surface. No tires and
no diff on the car! A smooth table or desk should do. Be
sure that the rear bottom plate and chassis are in a
straight line, flat against the table, again, no tires on the
car. Lightly “tap” the chassis and rear pod releasing any
tension in the links. Keep the chassis flat on the table for step 4.
4 - Hold the chassis at the hold point “H”
by pressing
the chassis down to the table. Slowly tighten the 2 locknuts that
secure the center pivot assembly. For now, just lightly
snug one side then the other.
5 - Pick up the car and check the pivoting action of
rear lower plate. Rotate the rear plate from side-to-
side. It should move free without binding or "clicking".
If it does not, loosen the pivot locknuts and repeat steps 3+4.
If it rotates smoothly, tighten the locknuts on the center pivot more
securely. Do this by again holding the chassis down to the table at the
hold point “H”. Slowly and carefully, fully tighten the locknuts that hold the center pivot
assembly to the chassis. The handling of the Battle Axe hinges (pun intended!) on the
free movement of this rear plate. Be sure that the rear links and rear plate are free and not binding.
