Frustrated with the programming challenges that come with Ailerons and Flaps on a sailplane?  Tired of conflicting "how to" posts on line?  If features like Differential, Adverse Yaw, Elevator Compensation, Aileron to Rudder mixing, Snap Flaps are new to you, then this Guide and SPM file are for you.  

Everything you need for your Radian Pro is provided. This bundle includes a 96 page Guide, a prepared SPM file you to download into your radio along with 23 new Flight Mode voices and a reorganized Audio file. The prepared SPM file is specific for the Radian Pro.  All the rates, mixes and Flight Mode features are already programmed.   

The guide starts off explaining how to import the files into the radio, rename them and organize them.  The with the radio in your lap, the guide walks you through how the programming works from a generic perspective.  From there the guide shows you how the template sets up the radio and telemetry and how to adjust them if you need to. 

Next, the guide shows you how  to make simple modifications to the airframe and linkages and how to use Global Features to setup a neutral sailplane that is ready for programming.  After performing this step, the preset values in the SPM file are going to be very close. 

The guide then explains the Flight Mode Features that exist in the prepared template and how to adjust them. 

The last chapters are all about the new terminology that comes with an aileron sailplane, what the new control surfaces do and why and how to overcome issues like adverse yaw. 

Finally, the Guide explains and how to make the critical CG determination so the final elevator trim setting for each Flight Mode work together and how and when to use the different Flight Modes. 

The features include in the template include: 

• As a safety feature, the radio will not turn on until you retract the flaps and turn off Launch Mode (so the motor does not accidently start during startup).
• Elevator and Ailerons on the right stick and Rudder and Flaps on the left stick.
• Five flight modes are active, Speed, Thermal, Cruise, Launch, and Land.
• Throttle Cutoff is available on Switch H.

• Launch Mode: (announced with voice)
• Launch Mode switch starts the motor. Please remove the propeller before you start programming.
• Switch Selectable with priority over all other flight modes.
• Differential rate of 70%.
• Appropriate changes in Rates, and Aileron to Rudder mix.
• Camber Slider is off.
• Aileron to Flap mix is inactive.
• Launch Mode Switch starts and stops the motor.
• Launch Mode Switch starts the timers.
• Throttle Cut Switch announced with voices.

• Cruise Mode: (announced with voice)
• Neutral trailing edge Camber Preset.
• Camber Slider is active. Camber Slider only droops the trailing edge.
• Appropriate changes in Rates, Differential and Aileron to Rudder mix.
• Aileron to Flap mix is available with adjustable Flap Differential.
• Snap Flap is active.
• Additional down elevator to help push over at the top of the zoom.
• Voice announces altitude automatically at pushover at the top of the zoom.

• Speed Mode: (announced with voice)
• Reflexed trailing edge Preset.
• Camber Slider is active. Camber Slider only droops the trailing edge.
• Appropriate changes in Rates, Differential and Aileron to Rudder mix.
• Additional down elevator to help push over at the top of the zoom.
• Snap Flap is active.
• Aileron to Flap mix is available with adjustable Flap Differential.
• Voice announces altitude automatically at pushover at the top of the zoom.

• Thermal Mode: (announced with voice)
• Drooped trailing edge Camber Preset.
• Camber Slider is active. Camber Slider only droops the trailing edge.
• Appropriate changes in Rates, Differential and Aileron to Rudder mix.
• Aileron to Flap mix is available with adjustable Flap Differential.
• Snap Flap is active.

• Landing Mode. (announced with voice)
• Pulling the flap stick below 92% automatically activates Landing Mode.
• The 92% kick point can be modified.
• Adjustable Flap travel.
• Two methods to match Flaps so they move together.
• Either Flaperon or Crow.
• Flap to Elevator compensation expo curve with seven points.
• Appropriate changes in Rates, Differential, Aileron to Rudder mix.
• Extra down elevator to help push over in the landing zone.

• Master volume on the Right Knob. (if knob is available on your radio)
• Option for cross trims, placing the elevator trim on the Flap Stick side.
• Appropriate voices for each flight mode and telemetry if a telemetry module is installed.

• A timer that keeps track of accumulated motor run time. Timer switch is linked to the Launch Mode Switch so the timer starts automatically when you switch into Launch Mode and stops when you toggle out of Launch Mode. Start and stop as often as you like and this timer will only track accumulated motor run time.
• A timer that keeps track of accumulated flight time. Timer switch is linked to the Launch Mode Switch so the timer starts automatically the first time you start the motor and continues running when you toggle out of Launch Mode to stop the motor.

• If you have telemetry: (Either a TM1000 or one of the new telemetry enabled receivers)
• Telemetry can be recorded for later playback.

• You can track signal quality (by each individual antenna) between the transmitter and receiver and voltage without additional sensors.
• Add either an altimeter or variometer sensor and the transmitter will announce altitude when you push over at the top of the zoom.
• Add a current sensor and the transmitter will announce the gas remaining in the tank. (current left in the battery). This a WAY better method than tracking voltage.
• Add a 40G Load sensor set to record Max load and you can read the Max G load in real time. Great for working on your launch technique.
• Add a GPS sensor and you get straight line speed, distance from the pilot and location in the event you lose the aircraft.
• You can record telemetry with Switch A that is automatically saved to the SD card for later play back.
• Switch D is setup to call out altitude on demand and mAh used on demand.
