  • Feature: RED led will flash if excessive voltage detected
1.28 Beta 07/21/10
  • Bug fix: Update using USB connectivity on Mamba Max could cause USB connectivity to fail
  • Bug fix: Mamba Monster V5 fan ran during link, could cause link issues on some PC's

  • Bug fix: Mamba Monster/Mamba Max Pro fan wouldn't operate properly while in neutral
1.27 Beta 07/19/10
  • New Feature: Torque control - limits the amount of torque applied to wheels during acceleration.
  • New Feature: Added Max Forward Throttle feature that limits the maximum power output to motor.
  • Addition: Added support for Mamba XL/Mamba XL HV/Hydra ICE/Hydra ICE HV with data logging.
1.26 Final 05/13/10

Mamba Max Pro / Mamba Max Pro One Cell ONLY:

  • Added support for ROAR spec class racing. Neutral LED flashes when controller is NOT running in CHEAT mode.
1.25 Final 02/12/10

Mamba Max Pro ONLY:

    • Bug fix: Sensorless start was rough at low speeds
1.24 Final 10/25/09
  • Fixed stick programming of brushed modes
  • Fixed max drag brake not working
  • Fixed punch control stick programming comming up invalid value
  • Fixed power limited takeoffs with very high roll-out vehicles in sensored mode
1.23 Beta 10/08/09

Mamba Max:

  • Added ability to program Mamba Max via the receiver cable with a Castle-Link device (instead of being required to plug the unit into a USB port)

Mamba Max Pro:

  • Increased the possible timing advance range for C.H.E.A.T. mode
  • Increased power output while in C.H.E.A.T. mode
1.22 Beta 08/03/09
  • First public release of Mamba Max Pro controllers
  • Improved the performance low-speed operation of sensor-less motors
1.21 Beta 05/07/09
  • Added ability to change the 'Auto-Lipo' cutoff voltages
  • Added ability to turn off the power-on reminder beep
  • Improved low speed operation, detects and escapes cogging better
  • Added ability to reverse motor direction by Castle Link software
  • Added Mamba Max Pro software
  • Bug fix: Rare instance where throttle was applied and controller would stay in idle
  • Bug fix: Audible power pulse in transition from throttle to drag brake
1.20 Final 10/21/08
  • Added a check for over-temperature condition (If unit over-temps it must cool down before restarting)
  • Added an alert for the user that an over-temperature situation has occurred. The controller will now flash the RED and YELLOW LEDs. Please consider changing your gear ratio or reducing the number of cells in order to prevent the controller from being stressed to a thermal shut down.
  • Added an alert for the user that that a low voltage situation has occurred. The controller will now flash the GREEN and YELLOW LEDs. Running your controller to low voltage cutoff may be hard on your batteries.
  • Mamba Monster starting parameters modified to resolve some premature failures.
  • Fixed bug that caused excessive current-draw during beeping. Under some circumstances this bug could lead to premature failure of Mamba Monster controllers.
1.19 Final 08/15/08
1.17 Final 01/22/08
  • Force a full re-arm after manual programming
  • Minor bug: setting drag brake via stick programming showed a custom value of 1% below the desired value on Castle Link
  • Minor bug: Loading and saving programming information to a file did not properly update calibration data
  • Added tone that repeats every ~20 seconds to let user know a battery is plugged in
1.16 Beta 01/21/08
  • New start algorithm vastly improves cogging, rolling backwards starts, and general throttle feel.
  • Added Throttle Dead Band adjustment
  • Added Arming Time adjustment. This is used so that spread spectrum receivers have time to synch before the unit becomes armed.
  • Added brushed motor support. See wiring diagram. NOTE! Ensure that the proper mode is selected on the ESC for your motor wiring, failure to do so will result in controller damage, and will NOT be covered under warranty!
  • Added calibration information to Castle Link display
  • Initial release for Sidewinder ESCs
