Team Cayote has officially unveiled its brand new Crest X Evo speed controller, which achieves five times the computing power of the Crest X. The Crest X EVO is equipped with a powerful ARM architecture featuring a 32-bit Cortex-M4 core processor with a clock speed of up to 108 MHz. As a result, complex calculations are processed faster, which leads to an improvement in acceleration and braking performance.

This significant increase in performance ensures greater responsiveness at high speeds and multitasking controls, as well as improved reliability and precision in high performance applications.

Key features

• Metal frame fan with four-ventilation cooling system

• Customisable external switch interface
• Advanced reverse polarity protection + comprehensive safety features
• Wireless control via BTUNE module
• APP data logging function
• Leading the acceleration revolution
• Precise PWM frequency tuning for throttle and brake

• Electronic speed controllers in RC modelling - more control, more driving fun

  Electronic speed controllers(ESC for short) are the centrepiece of modern RC models. Whether it's an RC car, aeroplane, helicopter or boat - speed and handling cannot be optimally controlled without a precise speed controller. In this article, you will learn everything you need to know about the functions, advantages and selection criteria of electronic speed controllers for RC modelling.

  What is an electronic speed controller?

  An electronic speed controller controls the speed of the electric motor in a remote-controlled model. It receives signals from the receiver and regulates the power that is passed on to the motor accordingly. This allows you to accelerate, brake and (with bidirectional controllers) reverse with precision.

  Modern ESCs also offer numerous additional functions such as:

  • Soft start for a smooth start

  • Brake modes (e.g. drag brake for crawlers)

  • Motor timing for fine-tuned performance

  • LiPo undervoltage protection for battery safety

  Brushed or brushless - which type of speed controller is the right one?

  With electronic speed controllers, a distinction is made between brushed controllers for brushed motors and brushless controllers for brushless motors.

  Brushed ESC

  • Simple design

  • Less expensive

  • Suitable for beginners

  Brushless ESC

  • Higher efficiency

  • More power and durability

  • Ideal for ambitious pilots and racers

  Important: Brushed and brushless systems are not compatible with each other. Therefore, make sure that the speed controller and motor are compatible.

  Important criteria when buying an ESC

  When buying an electronic speed controller for your RC model, you should consider the following aspects:

  • Current carrying capacity (amperes): Must match the power consumption of the motor

  • Number of cells (S): Compatibility with the battery used (e.g. 2S, 3S LiPo)

  • Operating mode: Forward / reverse / brake - depending on the intended use

  • Programming: Many high-quality ESCs can be individually configured via program card or software

  Conclusion: The right speed controller makes all the difference

  A high-quality electronic speed controller noticeably optimises the handling of your RC model. Whether you are looking for a powerful brushless system for high-speed racing or a sensitive controller for scale models - with the right choice, you will get the most out of your vehicle.

  Tip: Look out for brand quality from proven manufacturers such as Cayote or Hobbywing to ensure long-term fun and reliability.
