SystemThe System-tab is the most complex tab and allows for a widevariety of changes. In the picture above, you can see that thedifferent functions are marked with red numbers in red boxes.The functions of those numbered options are: Return-to-home heightHere you can set the minimum flight height that yourGravit shall have when returning to home.Example: Let’s assume you fill in a value of 15 meter. Thiswould mean that if your Gravit returns to home, it willclimb to a minimum height of 15 meters BEFORE doing so.If the height is ABOVE 15 meters, it will KEEP the height.The default value is set to 10 meters. Return-to-home after voltage alarmIf this options is checked, the Gravit will return-to-home af-ter the voltage alarm is triggered INSTEAD of auto-landingon the spot.The default value is “checked”. Geo-FencingHere you can set the height and distance limit for the Geo-Fencing feature by using the sliders.- Height can be set anywhere from 0 to 255 meters- Distance can be set anywhere from 0 to 1000 metersYour Gravit will stop AUTOMATICALLY when it reachesthe limits in horizontal direction (=distance) or verticaldirection (=height).This is a safety feature which should help you from flyingthe Gravit too far away and out of your control/view.The default values are 50 m for height and 150 m fordistance.IMPORTANT: Before you change those values, keep thefollowing in mind:a) In some countries (or areas), the maximum flightheight may be restricted. Please check with your localauthorities for details.b) When flying the Gravit too far away, you may loose itout of sight. In this case, initiate a “Return-to-home(RTH)” by switching the SWA of your TX to the lowestPos. 2.c) In some countries you may NOT allowed to fly the Gravitout of your line of sight. So if you fly it too far away,you might not only loose it, but you may also violatethe law.d) DO NO SET THE VALUES TO VERY LOW NUMBERSOR EVEN ZERO!LRP strongly advises NOT to set the numbers to unreaso-nably low numbers. More specific, LRP does not adviseto use numbers below 20 m for EITHER height or distancesetting. The reason for this is that too low values will resultin communication problems between the GPS and theflight controller. Please use values of at least 20 meters! Voltage alarmsIn this are, you can see three voltage values:“Voltage” This is showing the actual voltage of your connected bat-tery. If fully charged, this should be around 12.3V to 12.6V.“Alarm voltage” This is the FIRST low voltage threshold. When your flightbattery reaches this value, the Gravit’s status-LED givesout a warning signal, that is quick, red blinks. If you are inGPS mode, the Gravit will initiate a return-to-home. If youare in any other mode, you can continue to fly, but shouldland as soon as possible and replace the battery.“Landing voltage” This is the SECOND low voltage threshold. When it is trig-gered, your Gravit will either initiate a return-to-home ORauto-land on the spot, depending on the setting you havemade under point 2).SOFTWARE35
