Throttle Linkage - Duratrax Nitro Evader BX Assembly And Operation Manual

thread the receiver antenna through the antenna tube. The antenna
will be longer than the antenna tube. DO NOT CUT OR COIL THE
ANTENNA WIRE. Press fit the antenna tube into the hole in the
chassis. Tip: Run the antenna wire through your fingers to
straighten out the kinks before running through the antenna
tube. Also, applying a small amount of soap and water to the
antenna wire will help lubricate the wire for threading into the
antenna tube. Re-install the receiver box cover back onto the
receiver box using (2) 3x10mm pan head self tapping screws (I).

THROTTLE LINKAGE

1.Locate an "X" shaped servo horn (like the one above) that
came with your radio system.
2. Install the throttle pivot (149) in the hole 13.5mm [1/2"] from the
center of the servo horn and secure it with the 2mm e-clip (R).
Note: Use a hobby knife to slightly enlarge the hole in the
servo horn for the throttle pivot (149) to fit through. The throttle
pivot must rotate freely.
3. Locate the short linkage rod (144) and install the "Z-bent" end
into the lower hole of the engine's throttle arm as shown.
4. Install a 3mm set screw (K) into the linkage collar (146). Then,
slide the linkage collar onto the end of the throttle linkage (144)
and then the throttle linkage spring (148). Do not tighten the set
screw in the linkage collar yet. Install the straight end of the throttle
linkage through the hole in the throttle pivot (149). Install the
throttle servo horn onto the throttle servo. Do not install the servo
horn screw at this time. NOTE: Thread locking compound must
be applied in any step that requires a screw to be threaded into
another metal part. For example, when installing the set screws
into the linkage collars, apply a generous amount of thread
locking compound to the set screw before installing it into the
linkage collar.
5. Close the throttle to idle and make sure the servo horn is set as
shown in the above picture. Install a second 3mm set screw (K) into
another linkage collar (146) and then slide the linkage collar (146)
onto the throttle linkage (144). Slide the linkage collar (146) against
the throttle pivot (149) and tighten the 3mm set screw. Then slide the
previously installed linkage collar and spring against the other side
of the throttle pivot and apply a slight amount of tension against the
spring. Now tighten the set screw in the linkage collar. Note: This is
a good starting point for the linkage. Slight adjustments may
need to be made to obtain optimal performance.
