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”.

Click here for a diagram of Example 3.

‘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!

AUX What?!?

Adjective: auxiliary – providing supplementary or additional help and support.

Okay, we all get that. But what does it have to do with my speed controller?

When the Castle Phoenix Edge line was introduced for heli and plane applications, we announced the addition of the user programmable auxiliary wire. Our car enthusiasts will now have a taste of the simplicity and convenience if this feature with the Mamba X Series Electronic Speed Controllers (ESC).

In short, the auxiliary wire is an extra white wire, that when connected to an open channel on your radio, allows users to take advantage of on-the-fly adjustments (using your transmitter) that would otherwise be modified or set using the Castle Link Programming Suite. The feature is enabled through the Castle Link Programming system and one mode may be selected at a time.

Let’s take a look at the available options, we are certain you’ll find a favorite or two.

Mamba X Series ESCs (Mamba Micro X and Monster X)

Max Throttle Adjustment
The ESC’s maximum power is scaled from 10% to 100% depending on the signal received on the AUX wire. Perfect for passing the controls to children, neighbors or your boss.

Max Reverse Adjustment Mamba X Series AUX wire
The ESC’s maximum reverse power is scaled from 10% to 100% depending on the signal received on the AUX wire.

Max Brake Adjustment
The ESC’s maximum braking power is scaled from 10% to 100% depending on the signal received on the AUX wire.

Drag Brake Adjustment
The ESC’s drag brake setting is scaled from 0% to full brake depending on the signal received on the AUX wire.

Reverse Enable/Disable (Only works in modes with reverse)
Reversing is disabled when the controller receives an AUX wire signal above 50% (>1.5ms). When the controller receives an AUX wire signal below 50% (<1.5ms) or if the AUX wire is disconnected, reverse capability is enabled.

Torque Control Adjustment
The ESC’s torque control setting is scaled from 0.1 to 5.0 depending on the signal received on the AUX wire. Torque control is disabled when the input exceeds 1.9ms. Great for finding the perfect torque control setting for your track and tires. (Motor test must be performed before using this setting.)

Datalog Erase Enable
When the vehicle is stopped, toggling the AUX signal for a few seconds will erase the datalog. The motor will emit a long beep to indicate the log was erased. This feature can be added to any of the other AUX wire modes by checking the Idle Datalog Erase box in Castle Link.

Castle Phoenix Edge Series

Gain Input (ESC must be in a governor mode)
Connect the AUX line to an open channel on your receiver and use this mode to adjust the governor gain in real time. 0% TX signal equals a gain of 1 (min) – 100% TX signal equals a gain of 50 (max).

Phoenix RX+AUX wireTech Tip: Once the gain has been tuned via the Tx its value can be displayed on the data logger. Permanently save that value in the Edge via Castle Link programming and use the Aux. wire for another feature!

Audible Beacon
Connect the AUX line to an open channel on your receiver and this mode will use the motor to emit an audible locator signal when the AUX line is above 50%. The beacon is only emitted if the motor is not running.

RPM Out
Connect the AUX wire to 3 axis gyros that support RPM sensors and the ESC will toggle the AUX line at every electrical commutation. Divide this number by your number of magnetic pole pairs for mechanical RPM.

Arm Lock Key – requires ARM LOCK HARNESS
When the ARM LOCK key is in the socket, the controller will be incapable of arming. Once removed, the ESC will arm when it receives the low throttle command on the traditional throttle line.

RX Arm Lock

The controller won’t arm or run when the auxiliary channel is below 50% throttle.

Tech Tip: Loss of Aux wire signal during use reverts selected mode to default status.

So there you have it, the quick and dirty on Castle AUX wire functionality. Its sheer purpose is to provide at-your-fingertips options and adjustments to give you great flexibility, versatility and most importantly, the competitive edge!
