MOTOR GUIDE
Understand torque, speed, chassis compatibility and club legality.
SECTION 01
Read a motor by track requirement
- →Torque helps acceleration, climbs, repeated corners and recovery after lane changes.
- →Higher rotational speed helps long straights but increases heat and course-out risk.
- →A faster motor is not automatically faster on a technical track.
- →Dual-shaft PRO motors are for ME, MA and MS-family chassis; single-shaft motors are for compatible single-shaft chassis.
SECTION 02
Practical motor progression
| Motor group | Character | Typical use |
|---|---|---|
| Normal | Lowest stress and easiest control | Box Stock, learning and shakedown |
| Torque-Tuned | Strong acceleration | Technical tracks, slopes and heavier B-Max cars |
| Atomic-Tuned | Balanced | Mixed layouts and safe first upgrade |
| Rev-Tuned | Higher-speed bias | Longer straights and light cars |
| Light-Dash | Moderate dash step | Faster B-Max with manageable heat |
| Hyper-Dash | High all-round output | Experienced B-Max and Open setups |
| Power / Sprint / Mach-Dash PRO | High-output specialized motors | Advanced setups with strong brakes and stability |

SECTION 03
Motor preparation and safety
- →Use only unopened genuine motors. Do not remove the cap, change coils or alter brushes.
- →Run a short shakedown, let the motor cool and check for abnormal noise or smell.
- →Keep oil away from the commutator and track. Any leaking car can be rejected.
- →Match batteries as a pair and stop using cells with damaged wraps or labels.

BEFORE RACE DAY
VERIFY YOUR CLASS
Setup advice does not override the rulebook. Check the detailed class page and present uncertain configurations before official inspection.
