Hi all,
I'm having issues with my quadcopter, Most of the times it is flying perfect but sometimes and without any advise the copter loss altittude and crashes with the floor. The thing is that sometimes when reach the floor and the impact is not severe, i can recover the control of the drone and climb up again.
I noticed that it happens more time in moderate windy days.
Reviewing the log i see that the Thrust get 100% but the RCOUT to the motor are not at maximum. The thing is that sometimes is hovering normally at 50-60% of thurst and suddenly requires the 100% thrust (as reviewed in the log) and fall down.
Normally I flw in loiter mode, but i tried to change it to stabilize while falling but still continues falling, with the stick at maximum.
It is quite extrange because the drone is pretty stable and good maneuverability, i get speeds of 8m/s in loiter, and angles of 40º without problems (at the exception of this)
I tried with the ESC in NORMAL PWM and with OneShot 125, and the flight is quite similar, but with the second one appears this in the AutoAnalyzer: Test: PM = FAIL - 11 slow loop lines found, max 7.75% on line 21358.
I don't know if it is a problem of weight, bad configuration but this problem is grinding my gears.
The characteristics of my drone are the following:
Pixhawk 2.4.8
Frame F450.
4xMotors Emax MT2213
4xESC MakerStack / Makerfire 25A with BLHeli firmware 14.6
Plastic Props 1045
Battery 3S / 5500mAh 35C (i have 4, of two brands and happening the same with all)
Total Weigh 1720g With cam, 2axis gimbal, etcI attach a couple of logs where appears:
