Reely Raptor 6S - Changing the Motor Pinion

63
f) Changing the motor pinion
The vehicle is equipped with a motor pinion with 12 teeth. Another motor pinion with 14 teeth is included.
Usingthemotorpinionwith12teethresultsinbetteracceleration,butlowerendspeed(uptoapprox.90km/hwith
two 3-cell LiPo drive rechargeable batteries).
Usingthemotorpinionwith14teethresultsinslightlyworseacceleration,buthigherendspeed(uptoapprox.100
km/h with two 3-cell LiPo drive rechargeable batteries).
Important:
We recommend that you only use the motor pinion with 14 teeth if you can safely handle such powerful
vehicles. The high speed requires prompt responses when steering the vehicle. In addition, there must be
enoughspaceforoperatingthevehicle,becausethebrakingdistanceissignicantlylonger.
Proceed as follows:
• Turn off the speed controller and disconnect the two
drive rechargeable batteries from it.
• Loosen the three socket head screws (A) with a suitable
3 mm hex key so that the motor bracket (B) can be
pulled out forwards a little bit, as shown by the arrow
intherightgure.
Do not fully unscrew the three screws, only
unscrew them far enough for the motor bracket
to be moved.
• Loosen the set screw (C) of the motor pinion (D) with a
2mm hex key (F),then pull the motorpinionoffthe
motoraxle(notetheorientation).
• Putthemotorpinionwith14teeth(H)onthemotoraxle
inthe same orientationso that theat side isfacing
away from the motor.
• Applya drop ofthread-locking uid to the set screw.
Thenxthemotorpiniononthemotoraxlewiththeset
screw (G).
Makesurethatthesetscrewisexactlyontheatside
ofthemotordriveaxleandsecurelytightenedthere,as
shown in sketch (I).
Furthermore, make sure that the motor pinion rests
exactlyonthedrivegearandisnotoffsetlaterally,as
shown in sketch (J).
• Now adjust the backlash, as described in chapter 11. g)
below. It also details when and how to screw the motor
bracket.
