    How to install 3DR Radio Telemetry to APM 2.5 Quadcopter 

    This is a guide on how to install 3DR Radio Telemetry to the APM 2.5 board. By default, the installation is easy and does not involve a lot of tinkering. What you would need are an APM 2.5 board, Li-Po battery, land telemetry module and air telemetry module (see figure below).

    5. Look at the top-right, you should see that the Mission Planner and the APM 2.5 is not yet connected. Take note on which COM port your land telemetry was installed. Mine is COM 4. The baud rate shown besides the COM port should be set to 57600. Once done, click CONNECT.

    6. A pop-up (Connecting Mavlink) should come and shows that the parameters are being downloaded from the board to the Mission Planner.

    7. After a few seconds, the APM board and Mission Planners should be connected. The CONNECT button turns green. Now you can see the battery percentage, accelerometer level and set the waypoint wirelessly from your laptop to the APM board.

    8. Finally if you hate the mess, get some cable-tie to clean up the arrangement on your quadcopter
