Guide on Installing RadioLink AT9 into FreeX SkyView
We have seen on many YouTube on RadioLink AT9's ability to control over very long distance, and would wish to control FreeX Skyview over those distance. Follow these steps to make FreeX Skyview listens to AT9 and improves the responsiveness and reliability of FreeX Skyview. All works as per SkyView controller except for the way to switch the failsafe mode.
Step 1. Make your AT9 throttle stick self centering.
FreeX Skyview is programmed to lock arming if throttle stick is not self centered. Use the additional spring and level in your RadioLink AT9 set onto the throttle stick (as shown by the red arrows) after you open the RadioLink AT9.
Step 2. Install Radiolink R9D onto FreeX Skyview
You can use channel 7 and 8 to control your gimbal using AT9 dials.
Step 3. Create Skyview profile on AT9
In Basic Menu of AT9, go into Model Sel. function and create a profile for your FreeX Skyview. A profile is to contain all radio control settings of your craft. It is important to select the correct profile before flying.
Step 4. Select Model Type for FreeX Skyview
In Basic Menu of AT9, go into Model Type function and select Aircraft (with quadcopter symbol). Save before exit. QuadCopter type preconfigured Switch C and Switch D for switching between 5 flight modes (i.e. Altitude, GPS, Return-to-home and etc). As FreeX SkyView only has 3 flight modes, only Switch C is used to switch between FreeX flight modes (Off, GPS, Return-to-Home).
Step 5. Assign channels for FreeX Skyview IOC mode and Gimbal control
Go into AUX-CH to assign SwA to Channel 6. Channel 6 will be the channel to switch between Attitude and IOC mode of FreeX Skyview. Besides Channel 6 assignment, you may wish to use the levers on the AT9 to control the gimbal. In this example, Channel 7 is assign with VrA switch
Step 6. Reverse the channel of AT9
Go into REVERSE function to reverse Channel 1 to 6 as shown.
Step 7. Adjust the END POINT to tune the sticks limitsFirst, power FreeX Skyview (without props) and AT9, and use FreeX Flight Controller Tool V2.0 to connect into FreeX Skyview using USB dongle.
Go into END POINT function to tune Channel 1 to Channel 6 control signal falls between 1000 (lowest point) and 2000 (highest point). Move every sticks and switches on your AT9 and observe the control signal value under Remote Controller Signal in Flight Controller Tool v2.0 as you move the switch to the highest and lowest point of each channel. Adjust the END POINT of each channel until the lowest point and highest point are either 1000 or 2000.
Step 7. Adjust the SUB-TRIM to center the sticks
First, power FreeX Skyview (without props) and AT9, and use FreeX Flight Controller Tool V2.0 to connect into FreeX Skyview using USB dongle. Go into SUB-TRIM function to tune Channel 1 to Channel 4 control signal to fall at 1500 when the stick is centered. Keep the sticks center (that is no movement) and observe the control signal value under Remote Controller Signal in Flight Controller Tool v2.0. Adjust the SUB-TRIM of channel 1 to 4 until the Remote Controller Signal read 1500 for each of these channel.
Step 8. Set Failsafe (F/S) to return-to-home or hold position when signal lost.
Go to F/S function and program the receiver to set channel 5 to the 93%. 93% correspond to the control signal to "RETURN-TO-HOME" and the FreeX Skyview will return home when signal lost. Set about 50% to set failsafe command to "GPS HOLD".
Step 9. Routine Check
First, power FreeX Skyview (without props) and AT9, and use FreeX Flight Controller Tool V2.0 to connect into FreeX Skyview using USB dongle. Before taking your FreeX Skyview out to fly, ensure that the Flying Status is as per you had configured as you move the sticks and levers, that is
1) Switch C (highest position shows manual, middle position shows GPS, lowest position shows return to home)
2) Switch A (highest position show manual, lowest position show IOC),
3) Power off AT9 control will show the correct GPS mode status (either return to home or GPS hold),
4) All Remote Control Signal shows 1500 when the sticks are centered.
