Spirit System

New version 4.0.1 released!


Fine-Tuning update with a major tweaks for all Spirit units is available now!

Changes are following:

• Pitchup Compensation algorithm:
  • Pitchup Compensation was enhanced to compensate pitch deflections more precisely during pitch pumping.
  • We recommend to set Pitchup Compensation to 1 and start from there. Too High value could induce Aileron oscillations.
• Cyclic Gain tuning:
  • Cyclic Gain has no impact on steering response anymore.
  • Stick Response latency with a higher Gains was decreased to achieve as direct feeling as possible.
  • Cyclic Feed Forward can be decreased.
• Cyclic Feed Forward tuning:
  • Because of Cyclic Gain change it is possible to reduce Cyclic Feed Forward noticeable without loosing quick response.
  • Default Cyclic Feed Forward is 4 now.
• Rudder Automatic Centering:
  • From now rudder will be automatically centered even if Head Lock mode is active.
  • Centering is very slow and will happen only if no model motion is detected.
  • Automatic centering will help pilots to safely lift off in case they forgot to check the tail.
• New Swashplate - Dampening algorithm:
  • This parameter can greatly improve stopping performance.
  • Higher value will increase Integral Decay rate for Cyclic.
  • Higher value will allow faster and cleaner Stopping, mainly for Elevator axis.
  • Too high value (40+) could reduce Hovering stability.
  • Default value was changed to 10.
• New Rudder - Smoothing algorithm:
  • Smoothing algorithm was reworked for improved stopping with a Low RPM.
• Receiver Data Processing:
  • Swashplate and Tail control has new algorithms that are extrapolating Input for all radio connections running at a slower Frame Rate than Servos. This will make all movements smoother.
  • Collective Pitch control has no visible steps and servos will move cleaner.
• Elevator Filter:
  • Elevator Filter has additional Derivative bandwidth filtration from the Motion Sensor.
  • This can noticeable reduce Servo Load, Temperature and Consumption.
• Rudder Delay parameter:
  • Effect of Rudder Delay was lowered little bit to reduce Servo Load.
  • Additional filter was added for further reducing Servo Load and Servo Temperature.
• Spirit Settings software:
  • Gyro Gain between Spirit Wave and Spirit Settings software was equalized.
  • Fixed unstable connection with Wifi-Link on Mac.
• Motion Sensor Filter:
  • New Strong option for the sensor filtration.
  • Suitable for models with extremely high vibrations where Standard and Low Latency option can't work.
  • Available for Spirit GT, GTR and W1 units.
• YGE ESC Setup support:
  • Compatibility with the latest YGE ESC firmware was fixed.
  • The ESC will work out of the box with full Telemetry and Integration support when using Spirit Wave radio.
• New Scorpion ESC Setup support:
  • From now all Scorpion Tribunus ESC can be directly configured through Spirit Wave radio.
  • Wiring require no change from Scorpion ESC guide. Only Telem UNI cable is required to make it work.
  • Make sure that Spirit Wave is updated to the latest 1.0.25+ firmware.
• Scorpion ESC telemetry:
  • Setpoint and PWM telemetry variables are available for Spirit Wave.
• XDFly/ZTW/OMP ESC Telemetry:
  • Current and Capacity measurement correction.
  • XDFly manual guide was separated to a new one: XDFly Guide
• JETI Telemetry support:
  • Added support for all JETI sensors, thanks to JETI Model! The sensors will use ESC Telemetry and GeoLink variables, depending on a Sensor type.
  • From now you can connect JETI sensors directly with the Spirit unit, allowing main variables to be displayed.
  • If some sensor is not support natively, it will automatically detect variables. Detection could take several seconds.
  • Wiring require Telem UNI cable (at the SAT1 port), while sensor itself has to be powered from BEC.
• F-BUS protocol:
  • Compatibility and Speed with F-BUS receivers was improved.
• GeoLink Return To Home function:
  • Automatic Home programming for Mode (4) was updated to update Lift Off position when Throttle curve is under 25%.
  • This will help Nitro/Gasser pilots to safely return model to a true Lift Off position.
  • Even that motor is idling it is able to save the position.
• Tandem Helicopter:
  • Tandem Helicopter support was improved for better stability and precision in flight.
• Spirit RX protocol:
  • When Clearing the logs remotely Mounting Position could be unexpectedly reconfigured with some units!
  • Base parameters such as Swashplate Type and Mounting Position can be reconfigured only with Throttle turned off for safety reasons.
  • Highly recommended to update to avoid this issue.

Update for the Spirit units is available in our Download section.

IMPORTANT: If updating from V3.X.X or older firmware please make sure to read ChangeLog for V4.0.0.
NOTE: It is recommended to lower Advanced/Cyclic Feed Forward by 1 - 3 points. Otherwise Stick Response could be too agressive. Value 4 is suitable for the most pilots.
NOTE: It is recommended to set Expert/Pitchup Compensation to 1 for the first flight after update.
NOTE: It is recommended to set Expert/Swashplate - Dampening to 10 for the first flight after update.

Big thanks to Timo Wendtland for extensive support and testing!
