Step 36

 picsstep36-001.jpg (53711 bytes) Open bag number 6 
 picsstep36-002.jpg (60642 bytes) All the parts from bag 6.
 picsstep36-003.jpg (44915 bytes) For this car you need two high speed high torque servo's.
We use Hitec HS 925 MG servo's
 picsstep36-004.jpg (47137 bytes) The steering servo is placed in a holder.
The small 1,2 and 3 mm thick black plastic plates are to adjust how deep the servo is mounted in this holder.
Depending on the height of the servo you need to place them.
If you use the wrong thickness your servo can touch the front center chassis brace.
In our case we do not need to mount them.
 picsstep36-005.jpg (38238 bytes) Place the rubber grommets as they come with each servo and fit the servo as shown in the holder. Direct mounting without rubber grommets can cause premature servo damage due to engine vibrations .
 picsstep36-006.jpg (40313 bytes) Depending on the servo height place the black plastic adjusting plates in-between the bottom of the servo mounting lugs and the holder.
Fit at the rear side the black plastic screw blocks.
 picsstep36-007.jpg (43460 bytes) Secure the servo to the holder using 3 x 16 mm round head hexagon screws using a 2 mm hexagon tool.
 picsstep36-008.jpg (33737 bytes) We now are making one servo steering rod .
Take the two ball ends and the 3 x 36 mm left/right thread turnbuckle.
Place the left/right thread turnbuckle so that the marked red spot is at the right hand side.
 picsstep36-009.jpg (35628 bytes) Turn both ball ends on the left/right thread turn buckle using a pliers and a 4 mm wrench.
Make the distance between the red lines 19 mm.
We are going to adjust it in a later step.
 picsstep36-010.jpg (35050 bytes) Press at the left hand side a small ball and at the right hand side a large flanged ball using a pliers.
 picsstep36-011.jpg (54922 bytes) The kit comes with heavy duty universal adaptable servo arms.
 picsstep36-012.jpg (42876 bytes) It use inserts to adapt to the different brands and number of teeth of the servo output splines.
F code stands for FUTABA.
J code stands for JR PROPO.
S code stands for SANWA/AIRTRONICS.
This according to information from the manual and HN directly.

Look here for all info about servo output spline differences.

For the Hitec servo's we found out the F code insert worked best but we know the official number of teeth on the splines of Hitec is 23 where Futaba is 24.
So in case of doubt buy a dedicated heavy duty aftermarket or original servo arm.
 picsstep36-013.jpg (35387 bytes) Take this servo arm from the plastic tree.
 picsstep36-014.jpg (38700 bytes) Fit with a 3 x 12 mm round head hexagon screw the left hand side of the servo steering rod to the inner side of the servo arm using a 2 mm hexagon tool.
