Mamba X Series

New Features

  • Added new 'Auxiliary Wire Mode' 'Rock Race/Crawler Mode'. Allows the user to switch 'Reverse Type' to 'Crawler Reverse' and back to the Castle Link programmed 'Reverse Type' while adjusting drag brake using a third channel on your transmitter. Especially useful for crawler / rock racers. See Castle Link help for more information.
  • Added 'Idle/Error Beep Disable' setting to allow users to disable certain audible error warnings. 'Datalog Full' warning is now disabled by default. See Castle Link help for more information.
  • Added option to enable a sensor lost warning to 'SmartSense' mode.
  • Added 'Motor Temperature Cutoff' to Mamba X and Monster X.
  • Added 'CHEAT' mode to Monster X. (Not intended for 4 pole motors)
  • 'Motor Direction' was added to stick programming as the last setting #6. Option 1 is 'Forward' and option 2 is 'Reverse'.
  • Added new error condition for corrupted settings. Rapid beep with all LEDs blinking. Must be Castle Linked to repair.


  • Improved drag brake feel when transitioning between idle and power. Especially useful for crawler vehicles in both brushless and brushed 'Motor Type' modes.
  • Improved sensored motor start smoothness when drag brake is engaged. Especially useful for crawler vehicles.
  • Increased number of throttle steps for improved throttle smoothness.
  • Reduced minimum power levels. Especially useful for crawler vehicles. Reduced power jump when transitioning from high partial throttle to full throttle.
  • Decreased throttle latency, especially when using high RX frequency radios.
  • Improved sensorless motor start smoothness.
  • Improved motor timing accuracy.
  • Improved 'CHEAT' mode. Should result in an increase in motor torque in ROAR style Stock motor applications.
  • Increased the maximum sensorless electrical RPM to 200,000.


  • Replaced 'Max Forward Throttle' setting with 'Max Power' setting which affects both forward throttle and reverse throttle amounts. See Castle Link help for more information.
  • Replaced 'Max Reverse Throttle' setting with 'Reverse Percentage' setting which changes how much reverse throttle is allowed based on 'Max Power' See Castle Link help for more information.
  • Removed 'Brushed High Power' motor type mode. This mode could not supply more power than 'Brushed Reversing' due to current limitations on the negative ESC power wire. Therefore, it posed no advantage over 'Brushed Reversing'.

Bug Fixes

The following changes were made for the Mamba Max Pro only:

  • Bug fix: Excessively limited motor start power at high input voltages (6S LiPo input)
  • Reliability Improvement: ESC could damage itself trying to start a motor with a stuck rotor. Added failed start timeout.
  • Reliability Improvement: Mamba Max Pro thermal limit would not always protect ESC. Fixed.
  • Reliability Improvement: Added further protection against flash corruption which can cause ESC to become unresponsive.
  • Changed default cutoff voltage to 3.2V per cell.
  • Fixed issue that would cause the Sidewinder SCT to reboot on startup
    Added support for Sidewinder V2
  • Improvements to motor startup
  • Improved stability of Castle Link connection
  • Added additional error checking to prevent flash corruption during firmware updates
  • Bug Fix: Mamba Max Pro ROAR spec class neutral LED flash did not work on V1.26/V1.27.
  • Bug Fix: Mamba Micro Pro/Sidewinder Micro did not go to full throttle
  • Bug Fix: Some controllers did not require the user to recenter the stick after an overtemp condition
  • Bug Fix: Improved startup performance for some applications. Reverted to parameters from firmware V1.26.
  • Bug Fix: Data logging ESC's could make an audible click during the log write cycle
  • Feature: RED led will flash if excessive voltage detected
