Hello there again
Our LTE Long range Quadcopter build and configuration is done and we made the first long range (14km) auto mission today.
The mission was through a valley and i wanted to do exactly the same mission twice, once with the 10Ah battery (6S) and once with the 18Ah battery (6S) The first mission at 01 Pm succeded perfectly, the Auto mode was set to a speed of 14m/s (50km/h)
then after some reviewing of the logs and changing the battery, mission 2 started at 03:30 PM. after a few 100 meters i noticed lot of shaking on the HUD, GPS Glitch and High Z-Axis vibration.
i returned to Loiter mode and manualy fly back to the Launchpad. luckily without any damage or data link loss.
After reviewing the log and weather data from the local weather station i noticed that the wind increased meanwhile.
In the first flight the copters Pitch was about -20 degrees to reach target and -10 to come back. the -20 seems to be close to the limit before vibrations will rise.
in the second flight the pitch raised up and up to -30, i then canceled the mission because i felt unconfortable. so back in loiter pitch was still at -10 degrees in hover.
so here the question:
is there a way to set the max angle in Auto mode seperately or another way to limit the copters “wind fight behavior” to make sure the pitch will stay below -20?
i do not want to limit the angle overall, in RTL it can be important to go over that limit to reach home even when not flying stable…
any other suggestions about why virations are getting high at high airspeed would be highly appreciated. we are talking about a quadcopter with 17 inch propellers and BLheli ESCS (in D-Shot protocol)
