LIFTING ARM
2. After locating and drilling the hole, place the servo horn that came with your
servo in the .425 hole.
1. Start by taking the steel or carbon
fiber angle piece and drill a 0.425
hole on the left side.
Before you drill the main clearance
hole, take a moment to test-fit the
servo arm and ankle piece. There are
a large number of factors that could
change the positioning of this hole.
As opposed to altering the frame to
make the template work perfectly, at
this point, I would alter the
placement of the hole to make sure
the lifter fits.
3. Pick three of the small holes on the servo horn and drill them out to 1/8".
Drill three matching holes in the angle plate.
4. Put two 4-40 button head screws
with the head on the angle plate side
and the 4-40 nut on the servo horn
side.
5. Once you have attached your servo horn, it is time to attach the titanium
plate. Drill three holes in the titanium — 1/4", 3/4", and 1-1/2" from the top of
the plate.
6. Put the titanium
plate over the angle
bracket and trace your
three holes. Drill out
all the holes with a
1/8" drill, and screw
the angle bracket and
the titanium plate
together.
