VBar EVO V7 to V8 Update process and quick start guide

1. Connect WiFi to your VBar Control Touch or EVO radio and install the app “auto install notification”
   
2. Once that is done: update your VBar EVO (PRO or Rescue)
   
3. Connect your VBar EVO to your radio and after 10 seconds it will ask you to load the V8 setup app
   
4. Choose your preferred flight style from the list shown, once the VBar is connected the first time The converter will keep all previous setup values and will load all flight parameters regarding to your chosen flight style
   
   

Once that update and initial setup change is loaded, continue with these steps:

5. Go through the whole model setup and make sure everything is set correctly, it should be the same parameters and settings as before using V7. Please make sure to set the cyclic pitch value to exactly 8° in the model setup mode using a digital pitch leveling tool
   
6. Framerates and center pulses in the model setup:
   
   1. Main rotor: If your servos can handle 1520us/333Hz, please choose that setting first, if not, set it lower to match the specs.
      
      Please check both (upper and lower) endpoints of each servo to make sure your servo force is still applied to the endpoints
   2. Tailrotor: If your servos can handle 760us/1000Hz, please choose that setting, if not, set it lower to the servo specs (most servos can handle at least 500Hz) for the best tail performance results.
      
      Please check both left and right endpoints to make sure your servo force is still applied to the endpoints
   3. Governor: Same settings as before, we recommend using “VBar Governor”
      
      1. Recommended: If using “external governor”: use the RPM Signal. Plug the RPM Signal cable from your ESC in the “RPM” Signal port of your VBar EVO (can´t be used with Kontronik ESC´s)
      2. set motor poles and your main rotor gear ratio correctly in the model setup
         
7. Preparation before the first flight:
   
   1. Make sure all gyro directions are correct
   2. Check if the rescue horizontal calibration is correct (only for rescue firmware version)
   3. Check all parameters in your model setup
   4. Check your governor settings

First flights:

8. Tuning your main rotor flight parameters:
   
   1. Increase Main rotor gain (start at 72 (default), it should be possible to set 88-104 without any issues), set as high as your heli feels very stable and locked in
   2. Set your agility to reach your preferred maximum rotation rate (has to be set while doing full stick inputs for stationary aileron or elevator maneuvers)
   3. Set Expo as you like it
   4. Increase “control response” as much as you like a very direct feeling for stick inputs (start at 50, most 3D Pilots use 65 to 80)
   5. Set the stop support value as high as you get very crisp and locked in stops (mostly tune for elevator stops, start at 20)
   6. All values can be reached from the “second” main screen page: - swipe down from the main screen page once your model is connected. If the new screen is not shown, please "long press" next to the "V8" sign and reset that screen
      
      
      1. Press at the left side next to the "V8" logo to reset all flight parameters (Main/Tail/Gov)
      2. Press next to the Main/Tail area for a shortcut to the settings
   7. Do these steps for all flight banks/ RPM´s of your heli
   8. If needed, reset only your main rotor parameters in the flight setting panel:
      
      
9. Tuning your tail rotor flight parameters:
   
   1. Set the gain for all your RPM´s/ flight banks as high as possible without tail oscillating – same procedure as before (for high 3D headspeeds start at 45-50 and increase)
   2. Set the tail rotation rate as high as you like
   3. Set Expo as you like it
   4. Increase “Control Response” as high as you like the tail rotor to be very agile and direct to your stick inputs (start at 70 and increase, most 3D Pilots use 120 to 160)
      
      
      1. Press next to the Main/Tail area for a shortcut to the settings
   5. Do these steps for all flight banks/ RPM´of your heli
   6. If needed, reset only your main rotor parameters in the flight setting panel
      
      
10. Do the “autotrim” flight to make sure the pirouetting and leveling of your helicopter is perfect, do it in minimum/ no wind conditions
    
    
11. General Advice:
1. Do a Bench Test and add load to your Servos and BEC, watch the RC-Voltage at the same time, it there is a major drop
   
   
2. We recommend using a buffer pack for high amp. draws situations from your servos (e.g. Mikado Power Backup Part No. 05584)
3. We Recommend a capacitor for overvoltage spikes (e.g. 25v 2500uf)
