• Phoenix Ice 100 only: Fixed logging bug. Unit would not download logged data.

Phoenix Ice/Phoenix Ice HV

• Increased data logging duration by about 75%. Logged data is now compressed such that more data can fit in the confined logging space on the controller. As a result, maximum data logging duration is now approximate. Sitting in idle or other situations where the logged parameters are not quickly changing will significantly increase your data logging duration.
• Changed the helicopter auto-rotation feature to make programming easier. (Setups that were working will sill work exactly as before) See below for details
• Fixed issue where governor mode would lock in too early creating a large power pulse during spool-up
  

Phoenix HV

• Made further improvements running out-runner style motors
• Changed the helicopter auto-rotation feature to make programming easier. (Setups that were working will sill work exactly as before) See below for details

NOTE: Auto-Rotation Setup Changes
In the new release the helicopter auto-rotation feature has been improved, however setups that were working before will still work in the same manner. The lower range or the -0- throttle has become more defined and with this you may have to recalibrate your throttle settings if your ESC will not arm. The auto-rotation feature has also been improved and the setup range has been expanded. With the new release the ESC will not arm if it is in a condition that could HARD START or start in the Auto-Recovery mode ( in prior releases the ESC could slow start the first time and hard start after the initial spool up). You will have to satisfy a -0- condition before the ESC will arm. The ESC must see -0- throttle to get to a soft start condition. The auto-rotation recovery mode is not in a range that can arm the ESC now.

• Auto-Rotate mode now works in 'Heli-Fixed' (not governor) mode
  
• Auto-Rotate engage is now a quicker and more linear ramp
  
• ICE Controllers could (incorrectly) quickly ramp to full throttle if in governor mode
  
• Occasional motor 'tick' while running has been removed
  
• Improved ability to run some outrunner-style motors, especially very high-inductance motors

• First public release of Phoenix ICE controllers
• Added 'Outrunner Mode' PWM Rate to Phoenix 35 and higher controllers
• Improved the performance of motor startup
• Changed governor mode behavior - the governor will no longer lock at low throttle outputs

• Improved startup for some out-runner style motors
• Added audible error codes to help trouble-shoot in flight problems
  
  
  After you land, simply go to zero-throttle and wait for the controller to beep out the error code.
  
  1 Beep - Start Failure (The motor was jammed or locked)
  
  2 Beeps - Low Voltage Cutoff (Your batteries are likely discharged. Check that batteries are fully charged and that your Phoenix detects the proper number of cells at power-up)
  
  3 Beeps - Over Current (Current draw exceeded the safe capacity of the controller)
  
  4 Beeps - Prop Strike Detected (Your motor stopped spinning freely. Check for proper operation of motor)
  
  5 Beeps - Poor Radio Signal (Signal from your receiver is corrupt or non-existent, check transmitter and receiver)
  
• Added 'Powered Up' beep to warn the ESC is armed and powered
  
• Added an 8KHz pwm mode
  
• Added support for control-line governor mode WITH braking enabled. All standard brake options apply.
  
• Added new setting 'Head Speed Change Rate' to control how quickly the governor modes change between set points
  
• Added new setting 'Auto-Rotate Enabled' to allow faster exits from auto-rotations maneuvers
  
• Added two new governor modes, 'Simple Mode' and 'Set RPM Mode'
  
  Simple Mode
  Allows a normal startup, 75% throttle equals 75% max power.
  
  Once the throttle input is constant for 1.5s governor mode will LOCK on that speed
  Further changed to the throttle input (after lock) will result in corresponding head-speed changes.
  
  Set RPM Mode
  Allows three distinct head-speeds to be entered into Castle-Link and will govern at those head speeds.
  
  Requires input for motor kv, motor magnetic poles, gearing, and battery
  
  Head Speed 1 is chosen by throttle inputs less than 50%
  
  Head Speed 2 is chosen by throttle inputs between 50% and 99%
  
  Head Speed 3 is chosen by throttle inputs greater than 99%
  
• Changed 'Spool Up' to have a more linear speed
• Changed gain settings to be consistent at different RPMs. Also changed the range of gain setting to be 1 to 32.

• Released to production

• Fixed bug in downline braking software, controller would not allow user to throttle up until motor had fully stopped
• Improved motor run code for better performance while running outrunner style motors
• Improved reciever signal processing to handle high frequency input
• Improved arming routine safety. Unit will not arm in noisy environments

HELICOPTER SPECIFIC:

• Added heli fixed throttle mode
• Added motor start power adjustment so that very high torque setups can be started smoothly (no kick)
• Added governor gain to achieve better RPM hold accuracy on varying helicopter sizes/weights
• Revamped governor modes that increase RPM hold accuracy and flexibility
• 2-4 second delay with loss of transmitter signal before motor is stopped in helicopter throttle settings

ALL FLIGHT MODES

• Added throttle response adjustment so that users can increase /decrease throttle change sensitivity
• Added error codes for problem resolution
• Greatly increased throttle resolution for smoother throttle response

• Separated 'Brake Strength' and 'Brake Delay' from 'Brake Type' across all controller versions
• Added ability to set 'Brake Delays to any 1/10 second between 0 and 1 second
• Added ability to set 'Brake Strength' to any value between 0% and 100%, allows for fine tuning of down-line speeds using the prop as an air brake
• Added 'Brake Ramp' which ramps the brake strength from 0 to the desired value in a specified amount of time, allows using high brake strengths without fear of damaging gears or firewalls
• Added ability to force older Phoenix-25s to use the high PWM rate (most motors), the low PWM rate (high-turn outrunners), and the auto select feature
• Fixed bug on new Phoenix-25s which caused units to fully re-arm after low voltage cutoff while running governor mode
• Decreased required throttle to enter programming mode to fix problems with some low-end transmitters
• Modified flash write routines to fix unobserved, but possible, loss of programming

• Increased throttle ramp up speed for all controllers
• Fixed bug on HV controllers (false cutoffs in "reverse" mode)
• Modified startup on HV controllers to decrease battery ripple voltage and stress on controller
