The ball differential has been adjusted at the factory for proper
“break-in”. Do not tighten the differential before the buggy has
been properly broken-in or you can damage the differential.
After running the buggy for 2 or 3 battery packs, the ball
differential will require readjustment. This is the “normal”
break-in period for the ball differential. You will hear a
“squealing” sound when accelerating from a stop and the
buggy will accelerate slower. This indicates that the
differential is properly broken-in and now requires
adjustment. Do not run the buggy again until the differential
is properly readjusted as follows.
Adjusting the differential is quick and easy. Access the
adjusting screw by disconnecting the rear camber link
(using pliers) at the right rear wheel. Rotate the wheel and
CV shaft out of the way.
While holding the left rear tire, tighten the adjusting screw by
inserting the included 3/32" L-wrench into the cap screw on
the right side of the ball differential. The screw should be
tightened until it is “just snug.” Caution: Do not over
tighten the adjusting screw or you will damage the
differential. Next, loosen the screw 1/8 of a turn.
Reinstall the CV shaft back into the differential and reattach
the camber link. The ball differential may need occasional
adjustment to maintain performance.
BEFORE EACH RUN
❏
1. Check to make sure that all screws are tight and there
are not any screws missing.
❏
2. Check to make sure that the transmitter batteries are
not low.
❏
3. Check to make sure that all of the moving parts of the
Evader move freely and do not bind.
❏
4. Check for broken or damaged parts. Replace any
broken or damaged parts before running the Evader BX Pro.
Running of the Evader BX Pro with broken or damaged parts
could result in damage to other parts.
❏
5. Check to make sure that the receiver and speed control
are still properly secured to the chassis.
❏
6. Check to make sure that all wires are properly connected.
AFTER EACH RUN
❏
1. Clean any large globs of dirt or debris from the chassis
and moving parts.
❏
2. Disconnect and remove the battery from the Evader.
❏
3. Check for any broken or damaged parts. This way parts
may be replaced before the next run.
AFTER EVERY 10 RUNS
❏
1. Check the servo saver for proper operation. During
normal maintenance, check the operation of the servo saver
by grasping the servo arm and linkage and turning one of
the front tires left and right. If the wheels turn without moving
the linkages and servo arm, then the unit is operating
properly. If the linkage and servo arm move, loosen the
knurled adjustment nut on the left side servo saver shaft. If
the servo saver becomes clogged with dirt, it may not work
properly which could cause servo or linkage damage. The
servo saver needs to be disassembled, cleaned and
readjusted. To safely adjust the servo saver, loosen the
knurled aluminum collar on the left side steering post
completely. Then reinstall 1½ turns onto the post. Retest the
servo saver as described above. Adjust the servo saver
tighter or looser if needed.
❏
2. Check to make sure that the bearings are free of dirt
and debris and roll smoothly.
❏
3. Check the shocks for oil leakage. If the shocks have
leaked any shock fluid out, you should properly refill the
shocks for best performance. Inspect the shock shafts for
deep scratches.
❏
4. Check the motor brushes for wear. If the motor brushes
are severely worn or discolored they should be replaced.
❏
5. Check for buildup and wear on the bearings of the
motor. If the bearings are dirty, use DuraTrax Power Shot
™
to
clean them, then relubricate the bearings.
❏
6. Check for proper gear mesh between the spur and
pinion gear.
