Adjusting the Brake Linkage
1. With the throttle in the neutral position, adjust the brake 
linkage rods as shown. Note the amount of thread showing on 
each brake rod.(Fig. 9)
The brake portion of the linkage adjustment is now complete. Do NOT proceed if the above test 
does not work, repeat the procedure if necessary. 
2. Slide the collar (black) along the front brake rod (upper) 
towards the fuel tubing, until there is no play left in the link-
age. The fuel tubing should NOT be compressed. Repeat this 
process for the rear brake rod (lower). 
NOTE: The upper adjustment rod is for the front brake and the 
lower for the rear brake (Fig. 10).
3. At the end of this adjustment process, the brakes should 
NOT apply any resistance at the neutral throttle position. 
From adjustment in step 2, the brakes may be applying some 
resistance which can be felt by rotating the spur gear by hand 
through the bottom of the chassis. To ensure there is no resis-
tance, rotate each of the adjustment knobs (blue) one turn in 
the clockwise direction (Fig. 11)
4. Check the adjustment, apply full throttle and return to neutral 
and check the brakes for resistance. Repeat a couple times 
and check for consistent operation.
5. Watch the brake linkage as the transmitter trigger is slowly 
moved to the full brake position. Adjust the brake EPA of the 
transmitter so that when full brake is applied the spur gear is 
diffi cult to turn by hand. The brake EPA can be adjusted later to 
get the desired amount of brake for various driving conditions.
8. Before proceeding, move the trigger to the full brake posi-
tion and check the throttle return spring to ensure that it is not 
compressed completely. 
NOTE: If the throttle return spring is fully compressed, the 
most probably cause is either the throttle servo arm is installed 
improperly or the EPA is set too high. Proper adjustement 
should allow for at least .250” (6.5mm) of additional movement 
in the full brake position.
