Tarot OSD video overlay system GPS TL300L Tarot 250


Review of OSD

Synopsis: TAROT OSD mini perfect for 250/300 quadcopter size, allows you to configure directly on your monitor/goggle. It is based off the Remzibi OSD, intended for a racing quad, but can be used on any FPV models. Uses barometer and GPS module, so the height and position are more accurate.

OSD video overlay system has the following features: VTx Voltage, Eng Voltage, Flight Time, Flight Speed, Flight Height (altitude), Home Direction, Home Distance, Total Voyage (duration), Lifting Speed (vertical), Longtitude Latitude (GPS), Satellite Number (Count), Azimuth (location of the plane in the sky from the perspective of the base station). HOME OK is set when 6 satellites count are met.

First Impressions: Initial test. Barometer Altitude 2m+- Distance from Home 1m+- which is fine . Voyage (Mileage) it seems to add up the gps drift; unless you need to know your mileage besides duration or voltage, i will turn this off. 6+ satellites within 15 seconds here. Home direction on two 300m flights were accurate.. just keep moving, as it uses the gps to determine directions, and it takes you home.  This light Tarot osd was designed for 250 size quad in mind, but i am slapping it onto any fpv models for a quick home direction and a way to recover a lost model by recording the gps positions.

Missions Recaps:  During a search mission, point of interests (POI) are logged, GPS co-ordinates will be communicated to the ground search crew as well as to the multi-rotors team.  Multi-rotors are sent out for a closer look at the POI.  We record the GPS as a means to recover a model aircraft too.
