Firmware 2.70a

New patch 2.70a  pre-release version is available for download.

Chanes and new features:

Fixed issue: OSD randomly  blinks in negative all GPS fields.
Fixed bug: OSD did not permanently store  0km/h takeoff speed value.
Fixed bug: OSD did not permanently store acceleration speed less than 0.4g

Ground Station: Added support for direct mavlink USART telemetry input.  Now GS can display telemetry data in mavlink format, log these data on SD card and control tracking antenna  based on mavlink data. This allows to use GroundStation with 3-rd party system (FS/OSD) equipped with mavlink telemetry downlink.


Firmware 2.70rc5 is ready!

New 2.70rc5 pack has changes  in OSD firmware:

-Added API command for setting altitude/course in HOLD mode

-Mavlink output  GPS_RAW_INT message has incorrect value of time_usec field.

-Udated procedure for proper handling  proprietary messages ($PMTK)  for  g.top015 GPS module.



Firmware 2.70rc4 is ready!

We decided to change this version number from v2.62 to v2.70 ,  so this release candidate has version number 2.70rc4.

In this version some minor bugs were fixed:


  • Added full support for Ublox N8 series (new GPS in Pitlab shop) with GPS/GLONASS/GALILEO and diagnostics options.
  • Added GPS_RAW_INT message in OSD mavlink output .
  • Initial/startup  throttle low checking level is changed from fixed 1100us into 100us above throttle trim (for internal combustion engines and some ESC with zero level above 1100us)
  • Bug fixed:  GLOBAL_POSITION_INT field ‘heading’ is now in centi-degree (previously was in degrees)
  • Bug fixed: GPS_SYS_STATUS field ‘current’ is now is in 10mA untis (previously was in 1mA units)


  • Initial/startup  throttle low checking level is changed from fixed 1100us into 100us above throttle trim (for internal combustion engines and some ESC with zero level above 1100us)


  • No changes


  • No changes




New firmware 2.62rc3 is ready!

New firmware is ready with some bug fixed and new features added:


  • Added message MAVLINK_MSG_ID_GPS_RAW_INT in OSD telemetry output with number of satellites.
  • Added option OSD menu->GPS settings->HDOP to set minimum HDOP value required for store base.
  • Added option for horizon (pitch/roll: AHRS_TRIM_X  and  AHRS_TRIM_Y) correction  for mavlink FC
  • Added support  for BATT_LOW_VOLT  settings
  • Added option for store trims in mavlink FC
  • Changed GPS protocol:  Removed GSV (satellites in view) message. This message may cause problems with UART communications when GPS is tracking extensive number of satellites (GPS+Glonass+Galileo)
  • Removed satellite status submenu (due to GSV message removal)
  • Removed DEMO submenu


  • removed bug with Minimum GPS speed settings (multiplied by 3)
  • Added safety feature: when AP is powered up with throttle stick up (above 1100 microseconds) AP will keep throttle output low (and other channels neutral) until  user moves throttle stick  down (below 1100us)


  • Removed problem with maps in Windows 8 (browser compatibility)


New version 2.62rc2 is ready

New version 2.62rc2 (release candidate 2) is ready for download – link for download is as usual on the left menu.

In this release some bugs are fixed:

  • sometimes OSD overlay disappears for a short moment.
  • Editing RC monitor in one layout may destroy settings for monitor on other layout.
  • Wind course from pixhawk was reversed (180 degree)
  • FPV_manager stores wrong altitudes to OSD when “Altitudes above” is set to “ground”

And some new functionalities are added:

  • New options for user A2 input (pulse high time, pulse low time , period, freqency, duty)
  • Added chackbox [x] always celsius in temperature field for some countries where imperial units  are in use except temperature (e.g. UK, India, Austrailia, New Zeland)
  • Automatic wake-up and re-initialisation of GPS in case of GPS errors during flight
  • Added option [x]elevation in variometer field which shows current airplane elevation and  current glideslope.
  • Option to show consumed Wh (watt-hours) instead of mAh in battery capacity field
  • Option [x] mute sound in variometer field
  • Waypoint maximum altitude extended up to 2500 meters
  • Autopilot’s maximum altitude limit for autonomous flight extended to 2500 meters
  • Added throttle management in takeof functionality (cut off or limit throttle on ground and enable throttle after acceleration/speed detected), for hand lanuch of flying wing or  catapult launch
  • Added advanced altitude RTH/RTR mode  with 3 defineable steps (initial circling up, flight level, flight down)
  • Added option for alternative elevation service in FPV_management (in case of slow main server response)

First release candidate 2.62rc1 is ready!

First firmware  2.62rc1 with status “release candidate” is ready for download.

Release candidate means that all functionalities are completed and tested, and all known bugs are fixed.  If no new bugs were discovered this version may become oficial release.

In this release:

-In OSD menu Service->GPS settings there is a new option GSP status, which shows detailed status of GPS. This option may be inoked also during flight.

-bug fixed in channel monitor, which also disturb wind assistant measurements.

-Added new RC channel monitor option for “centered” percentage indicator  with range  -100%….100%  and zero at 1500 microseconds.

-Waypoint list  for APM/Pixhawk shows now altitudes with proper type icon  (relative, terrain or above sea level)

-bug fixed with too long post -flight info  delay.


Firmware 2.62beta9 is ready!

After many tests and response from beta-testers new firmware 2.62beta9 is ready.

-Faster autopilot’s response  to mode change.
-Faster throttle response to AUTO mode change.
-Mountain mode initial circling radius is set to 100m  (can be changed during circling by rudder stick)
-Fixed bug in course to base indicator for APM/Pixhawk
-Automatic magnetic course selection for APM/Pixhawk
-Fixed bug in symbolic RC channel names recognition (throttle/pitch/roll)  for APM/Pixahwk
-In waypoint list now OSD presents azimuth/distance to next waypoint for APM/Pixhawk (like in MissionPlanner)
-Added option for clearing inactive buddy flight positions
-Added information about all buddy flight GPS positions  (in BuddyFlight submenu)
-Faster buddy flight position refresh
-zoom submenu moved into layout


2.62beta8 is ready!

Firmware 2.62Beta8 is ready to download.

In this release:

Added total flight time (sum from all flights) in post flight statistics page. For FC this is time when FC is armed, for single OSD and Pitlab AP this is time from system start (or last store base before takeoff) till landing.

Battery capacity/cutoff is readed from FC (pixhawk/APM) at startup, reflecting last FC settings made by GCS. And selecting battery from OSD menu sets new capacity/cutoff  to the FC.

In FPV_manager (page OSD ->settings) added options for reset/update odometer and total flight time.  Important for those who transfer OSD/AP to another airplane.
