Step 15. Place the center chassis brace (37) on top of
the chassis (27). Pay particular attention to the steering posts
(30) and the servo mounting posts (40). The chassis brace
has two extensions that fit over the steering posts (30), and
the pins in the top of the servo mounting posts {40) should fit
into two holes in the chassis brace (37). Once the chassis
brace is lined up and in place, secure it to the front bulkhead
{6} by threading two 8-32 x 1 /2" screws (28) through the for-
ward holes of the chassis brace (37) and into the holes in the
top of the front bulkhead (6).
Step 16. Secure the chassis brace {37} to the chassis
(27) with five 4-40 x 3/8" flat head screws (31} as shown.
*NOTE: Make sure that the pins on the top and bottom
of the steering servo mount stay located in the holes in the
chassis and the chassis brace.

There is an extra 4-40 x 3/8" cap head screw
packed in the wrench bag. This screw can be used to tap
the threads into all of the "Stiffezell" plastic parts such as the
center chassis brace. The larger cap head uses a 3/32"
wrench which will make it easier to start threads into the stiff
plastic than the small 1 /16" wrench used on the flat head
screws. The cap head screw should be threaded in about
half way and removed from each hole. This will make it easier
to install the flat head screws and allow for the last few threads
to be tapped when it is installed.

Step 17. Refer to figures 18A and 188. These are full size drawings of the throttle servo mounts (41) attached to the
chassis in the two different configurations. Hold your servo up to these diagrams and align the mounting ears on your servo to
holes in the mounts. This will determine how to mount the throttle servo mounts (41).
Step 14. Once you have determined the mounting position of the throttle servo mounts {41), attach each mount (41) to the
chassis {27) with two 4-40 x 3/8" flat head screws (31) so that the mounts are offset the correct way from figure 18A or 188.
*NOTE: If you do not have your radio system yet, or do not know which servo you will use for throttle at this time, attach the
servo mounts according to figure 1BA and continue. The direction of the mounts can be changed once you have determined
which servo you will use.
