TBS Crossfire Manual
Preparations
The find mode needs to be armed before it will take any action.
● Receiver only:
○ Power up receiver and transmitter and make sure they are connected to each other.
● Receiver with GPS:
○ Make all steps above and ensure the GPS is having a solid sat lock.
● Receiver with GPS and TBS CORE PRO:
○ Make all steps above and simulate a take off. This can be done throttle above 3A or
walking your receiver until you see the take off message on the OSD.
Simulating flight
The find mode is armed now and you need to simulate a flight. Just separate the transmitter and receiver
by more than 50 meters.
Simulating a Crash
A crash can happen in different ways. Let’s simulate it only :) Here are some scenarios.
● Turn off your transmitter ( failsafe ) and move your plane to another spot (scenario: flying behind a
mountain, with subsequent crash )
● Power down the battery (scenario: battery eject on crash)
● Just let it sit there (scenario: landing in a tree)
Search and rescue
The copter/plane is lost - now we’ll start the S&R mission. It’s important to get the link back to either get
the latest GPS coordinates or have the ability to point into the direction based on the signal strength.
● In some cases the link is not even lost. Skip below and move to “Link regained” chapter
● Read the coordinates from your OLED and go to the place of the latest coordinates. If you don’t
have a GPS try to go as close as possible to the last known position.
● Get yourself to an exposed position as close to the target as you remember from the crash or
based on OLED coordinates
● Toggle between find mode (greater range, less telemetry) and full link (less range, full telemetry). If
you have lost main power your quad will respond in find mode. For all other scenarios, you should
be able to regain control. When you see “find mode activated” on your LCD, give it more than a
minute before you deactivate it again ( beacon timing, see description above ). If you use the DIY
reflector point and hold in different directions until you get your link back.
