Pables and crowns: 48DP or 64DP?


In the exciting world of RC Drift, two crucial components play a major role in the performance of your vehicle: the gable and the crown. These elements of the transmission not only determine the speed and acceleration of your RC car, but also influence its ability to drive with precision and efficiency.

Pable and crown: Definitions

  • The gable is the small toothed wheel attached directly to the engine shaft. Its size and number of teeth are decisive in the transmission of the engine power to the wheels.
  • The crown is the great toothed wheel which engages with the gable. Fixed at the transmission shaft which causes the wheels, the crown receives the drinking force of the gable to propel the car.

Difference between 64DP and 48DP

The distinction between 64p and 48p lies in their "not" - the term "p" designating the "teeth", which measures the density of the teeth on a toothed wheel. The "step" is essential because it influences the softness of the transmission and the precision of the adjustment between the gable and the crown.

  • 64p : A finer step, with 64 teeth per inch. 64P systems offer softer transmission and are often privileged for competition and high precision applications, where meticulous control and acceleration control is crucial.
  • 48p : With a coarse step with 48 teeth per inch, 48P systems are robust and tolerant, ideal for beginners or for racing conditions where sustainability takes precedence over extreme precision.

Calculation of the relationship between 48DP and 64DP

The transmission ratio between the gable and the crown is crucial to optimize the performance of your RC Drift car. This report, generally expressed by a division (gable/crown), determines the acceleration and maximum speed of your vehicle.

The calculation of the report is directly influenced by the "step" because it determines the actual size of the gable and the crown that can be embedded together. For a given system, either 48p or 64p, you must first choose gables and crowns compatible in terms of step.

  • Crown conversion For RC Drift cars

From 64p to 48p

To convert the number of teeth of a 64p crown (pitch) to its equivalent in 48p, use the following formula:

Number of teeth in 48p = (64 / Number of teeth in 64p / 64) × 48

From 48p to 64p

To convert the number of teeth of a 48p crown to its equivalent to 64p, apply this formula:

Number of teeth in 64p = (number of teeth in 48p / 48) × 64

These formulas make it possible to maintain a similar physical dimension between the two pitch standards, ensuring optimal compatibility of the transmission components for your RC Drift vehicles.


This adjusts the number of teeth to maintain a similar physical dimension between the two pitch standards.
In summary, the Choice between 48p and 64p Depends on your performance and sustainability needs, while the precise calculation of the transmission ratio will help you optimize your RC Drift car for speed, acceleration, and desired handling.
