Electric RC cars and nitro cars use different types of clutches, and some use no clutch at all. Read on to learn about the types of clutches.
A slipper clutch allows the drivetrain to "slip" slightly as the car accelerates. It is intended to increase traction by preventing excessive wheelspin.
Direct drive (no clutch)
- Faster throttle response
- Less weight and rotational mass
- Requires more throttle control, especially in less-than-ideal traction conditions
- For off-road, this is sometimes used in stock racing applications where the increased throttle response is very important.
- Slower throttle response
- More forgiving to drive / less likely to break loose under power
- For off-road, slipper clutches are common, although some 4WD cars use a center differential rather than a slipper clutch.
Nitro cars use a clutch to allow the engine to continue to spin even when the car is not in motion. As you pull back on the trigger and increase the rpms of the engine, the clutch engages, making the car move forward.
The clutch shoes and clutch springs are contained within the clutch bell, as seen below. The clutch bell is usually one piece with the pinion gear. Read more about how the clutch works in our article on clutch bells.
