# 1 Flight Ctrl V2.5

The !Flight-Ctrl V2.5 is now equipped with a new pressure sensor and a more powerful ACC sensor. Now we have a significantly better height control and flights are possible up to 5000mtr. The FlightCtrl V2.5 is shipped with: already assembled cables for: • a PPM Sum signal receiver • and a Telemetry connection • already installed with the latest software • fully tested for functionality •
INFO: You can use the FlightCtrl V2.5 only with the MikroKopter Software since Version V2.00d ! TIPP: Below you can download a finished setting for the FlightCtrl where all functions are already set. New thing on the FlightCtrl V2.5: new Air pressure sensor (with light / wind protection) • new ACC-Sensor • better altitude control • less sensitive to vibrations (all Axis) • Altitude sensor work now up to 5000m • LEDs on the switching outputs • Voltage up to 6S (25V) • Protection resistors to the servo outputs • 400uF for better voltage regulation on the power supply • Note: Not compatible with older firmware versions! •
