Parts Included:
1. Install four flanged rod end balls into the rod ends. Install four
3x16mm set screws into the rod ends. Note: Once you feel the set
screw getting tight in the rod end STOP.
2. Install the rod ends onto the front lower links.
3. Assemble four more rod ends like in step #1. Install the rod ends
onto the bent rear lower links.
4. Mount your AX-10 transmission to the GC3-A skid plate using
four 3x14mm flat head screws. Note: Notice the direction of the
transmission on the skid plate.
5. Install the chassis side plates and lower links onto the skid plate.
Secure the assembly together using four 3x25mm button head
screws. Note: The bent lower links go in the rear.
6. Assemble eight more rod ends like in step #1. Install the rod ends
onto the upper links. Note: The shorter (83mm) rods are for the front
and the longer (89.5mm) rods are for the rear.
7. Install the upper links to the chassis using four 3x14mm button
head screws and four 3mm lock nuts. Note: The longer upper links
go in the rear. The upper links mount to the outside of the chassis
as shown.
8. Install the center chassis braces and secure them in place with
four 3x8mm button head screws.
Note: Use a generous amount of thread lock on the chassis brace
screws.
9.Insert the upper shock mount screws through the tops of the
shocks. The front shocks use 3x25mm button head screws and the
rear shocks use 3x27mm button head screws.
Next, thread the upper shock mount spacers onto the upper shock
mount screws. The front shocks use 7.5mm spacers and the rear
uses 12mm spacers.
Install the center chassis brace/upper shock mounts onto the chassis
and insert the upper shock mount screws through the shock mount
holes on the chassis and into the center chassis brace/upper shock
mount as shown.
Note: Use a generous amount of thread lock on the chassis brace
screws.
10. Attach the front shocks and front lower links to the front axle, the
shocks go to the inside as shown. Secure the assembly in place with
a 3x25mm button head screw and a 3mm lock nut.
Note: Depending on what shocks you use you may need to use the
included 3mm washer to properly space the rod end/shock end
between the mounts on the axle.
11. Attach the Axial servo mounts to the steering servo plate using
two 3x8mm button head screws as shown.
12. Attach the front upper links to the steering servo plate using
two 3x14mm flat head screws and two 3mm lock nuts. Secure the
steering servo plate to the front axle using one 3x10mm flat head
screw (see pic for location) and two 3x14mm flat head screws.
