R/C calibration
CORE PRO needs to be calibrated/mapped with the channel mapping from BetaFlight. Go into "FLIGHT
CONTROLLER", "CALIBRATION" and "READ FLIGHT CONTROLLER RC DATA". This maps the settings to the
CORE PRO and you are ready to go. Required procedure every time the R/C channel inputs are changed.
Changing VTX channel
The UNIFY PRO supports 37/24-channels and changes can be made "live" via the OSD.
1. Go into the OSD menu, then navigate down to "VIDEO TRANSMITTER" using the elevator-stick on
your radio, selecting it by moving the aileron-stick right
2. In this menu you can use the same navigation method to change the band and channel
3. Once preferred settings are set, use the aileron-stick to exit selection by moving to the left and
navigating out of the menu, only then will the new settings be made active on the UNIFY PRO VTX
This way of configuring the VTX this way is based on what we call SmartAudio. The CORE PRO uses the
audio channel from the UNIFY PRO as an exchange protocol to open a full duplex (back and forth)
connection between the VTX and the OSD. It is possible to change this behaviour via solder jumper on the
CORE PRO so you can either control the VTX channels and frequency via OSD, or just hear the sound from
the mic.
Changing VTX power level
The default VTX power level is 25mW and is fine for all close proximity flight where there are no other FPV
pilots around. In order to unlock higher power levels, you need to change your HAM callsign. Please note
that this requires a HAM license in most countries, which you are obligated to obtain before increasing the
power levels or switching to non-approved frequencies.
1. Go into the OSD and navigate to "VIDEO TRANSMITTER" and "UNLOCK VTX"
2. Change the callsign from the default "TBS"
3. Return to the "VIDEO TRANSMITTER menu and change to "VTX POWER LEVEL"
4. The transmitter power can be changed from 25mW all the way up to 800mW
For racing recommended power is maximum 200mW to avoid interference with other FPV pilots. Power
levels above this is only recommended when flying alone in wide open spaces.
