Castle Crawler & Scaler Series – Get the Lowdown on Rock Race/Crawler Mode!

With the recent introduction of the 1406 series brushless sensored motors in a “SLATE” color, Castle is taking  low RPMs very seriously. Months of hard work went into this release. We focused on several aspects to cater to the wishes of everyone who loves to run scale. Delivering monstrous torque and ultimate control, combined with the high end speeds that we are known for.

We have diverted from our traditional green color with slate colored cans making the motors less noticeable in your scale trucks. Simultaneously we wanted to mark a new product line for Castle Creations which emphasizes that we concentrate on low RPM control. Combined with any of our X series speed controllers these motors will enable you to fine tune and set the controllability of your ride to the maximum, or even use the aux wire to toggle between drag brake settings for example.

A brand new running mode is now available available on firmware version V2.02 (Click for complete summary of new features, improvements and changes)  and newer for the Mamba Micro X, Mamba X, Mamba Monster X and Mamba XL X ESCs. This is a mode which is designed to allow users to get the most out of their ESC when used in Rock Race or Crawler vehicles. While it can be rather confusing initially, when it is set up correctly it can be very beneficial.

This feature is accessed through the use of the programmable  Auxiliary Wire that is available on the Mamba Micro X, Mamba X, Mamba Monster X and Mamba XL X ESCs. The AUX wire function is disabled by default but is programmable via Castle Link. Once you have programmed the functionality of the AUX wire, that particular setting can then be adjusted on-the-go from a compatible transmitter. The ‘Rock Race Mode’ and ‘Crawler Mode’ allows the user to switch between two different modes on the fly: ‘Race Mode’ is optimized for either Racing/Bashing and ‘Crawler Mode’ is optimized for crawling.

Rock Race/Crawler Mode Overview

This auxiliary wire mode is designed to allow users to get the most out of their ESC when used in rock racing or rock crawling vehicles. This mode allows the user to switch between two different ‘Reverse Type’ modes on the fly: ‘Rock Race Mode’ and ‘Crawler Mode’. ‘Rock Race Mode’ is optimized for either racing/bashing and ‘Crawler Mode’ is optimized for rock crawling. It also allows you to adjust the motor’s Drag Brake based on the AUX wire signal.

Adjusting Drag Brake – While in this mode the motor’s Drag Brake percentage is controlled by AUX wire signal. At 1.1ms the Drag Brake will be disabled at 0% and at 1.9ms the Drag Brake will be set to 100%; it is proportional throughout the AUX wire signal range; IE at 1.5ms the Drag Brake will be at 50%.

Rock Race Mode – The ‘Reverse Type’ in this mode will be set to the Castle Link ‘Reverse Type’ setting on the Basic tab (default is set to “With Reverse”). Refer to “Reverse Type Definitions” at the end of the document for a full description of each ‘Reverse Type’.

Crawler Mode – The “Reverse Type” in this mode will be set to the Castle Link ‘Reverse Type’ setting on the Basic tab (default is set to “With Reverse”). Refer to “Reverse Type Definitions” at the end of the document for a full description of each ‘Reverse Type’.

Please see the examples below for a better understanding of how this works.

Note: If the AUX wire becomes disconnected, the controller will default to ‘Rock Race Mode’.

Example 1: Castle Link Settings: ‘Drag Brake’ – “0%”, ‘Reverse Type’ – “Without Reverse”

  • ‘Rock Race Mode’ is enabled whenever the AUX Wire Drag Brake is at or below 0% (? 1.1ms) and the ‘Reverse Type’ will be set to “Without Reverse”.
  • ‘Crawler Mode’ is enabled whenever the AUX Wire Drag Brake is above 0% (> 1.1ms) and the ‘Reverse Type’ will be set to “Crawler Reverse”.

Example 2: Castle Link Settings: ‘Drag Brake’ – “10%”, ‘Reverse Type’ – “With Reverse”

  • ‘Rock Race Mode’ is enabled whenever the AUX Wire Drag Brake is at or below 10% (? ~1.2ms) and the ‘Reverse Type’ will be set to “With Reverse”.
  • ‘Crawler Mode’ is enabled whenever the AUX Wire Drag Brake is above 10% (> ~1.2ms) and the ‘Reverse Type’ will be set to “Crawler Reverse”.

Example 3: Castle Link Settings: ‘Drag Brake’ – “50%”, ‘Reverse Type’ – “With Reverse”

  • ‘Rock Race Mode’ is enabled whenever the AUX Wire Drag Brake is at or below 50% (? ~1.5ms) and the ‘Reverse Type’ will be set to “With Reverse”.
  • ‘Crawler Mode’ is enabled whenever the AUX Wire Drag Brake is above 50% (> ~1.5ms) and the ‘Reverse Type’ will be set to “Crawler Reverse”.

‘Reverse Type’ Definitions:

  1. “Without Reverse” – Racing Setting. No reverse motor direction. Pressing the reverse trigger on the radio will engage the motor brake.
  2. “With Reverse” – For bashing or racing (may not be allowed in some racing situations). When transitioning from throttle to reverse the ESC will brake the motor. To run in reverse the ESC must see a neutral signal for at least 2 seconds before the reverse will engage when reverse trigger is applied.
  3. “Crawler Reverse” – The ESC will immediately spin the motor in reverse when the reverse trigger is pressed. The ESC will apply a brake to bring the motor RPM to zero before reversing the motor; this helps prevent potential damage to the vehicle’s drive train. This setting is recommended for low speed rock crawling; using this mode at high speed will result in an amazing front-flip, but expensive repairs.

Now that you have the lowdown on the newest features and optimizations, we hope you dig out that Castle Link and hit the trails!

New Castle Link version available: 3.57.12

There is a new firmware update available for ALL brushless aircraft Electronic Speed Controllers (ESCs), including the Phoenix, Phoenix HV, Phoenix ICE, Phoenix ICE HV, Phoenix Edge, Phoenix Edge HV, Talon, Talon HV, Multi-Rotor and Thunderbird. This latest update is V4.22

Castle_LinkThis latest release of Castle Link addressed the following issues:

  • Bug fix for firmware version 4.20. Some users experienced problems reengaging the throttle after the brake was turned on at zero throttle. This issue only occurred when the brake feature was utilized.
  • Adjusted software to improve performance under heavy load.
  • Talon 15, Talon 25 and Multi-Rotor 25 had their current limit setting removed due to inconsistent operation. The software has been adjusted to measure excessive current using other means.

This latest version gives all ESCs access to features that were added to firmware version 4.20.

Firmware version 4.20 for aircraft ESCs has been “broken arrowed”. This means that any ESC that is currently utilizing firmware 4.20 and is connected to the new version of Castle Link (3.57.12), the program will NOT allow you to change ESC settings and you MUST update the firmware to version 4.22.

We also made some edits to the text of the “connection status” boxes to make it easier for users to determine whether their status is connected or disconnected. This was done to help red/green color blind users determine the connection status of the Castle Link and ESC.
