Just updated to 2.9.1. Worked great in previous version.Set up a quick mission. 200 meters west, delay for 15 seconds and then RTL.Manually launched and switched to auto. The hex headed toward the waypoint but started losing altitude very rapidly. Took it back manually and landed thank god.Altitude hold works perfect. I am at a loss.Help.
You need to be a member of diydrones to add comments!
Z-accel is really good with a standard deviation around 5 (engineer here created an incredible damping system.
altitude hold is right on and very stable.
Question: are we still using AGL of have we converted to MSL altitude. Verify altitude programs MSL altitudes with waypoint assignment. Last flight I used MSL altitudes and it still dropped like a rock as if it was trying to correct a very large altitude error.

My problem with altitude loss in auto SOLVED !!! :-D
It was my fault... :-/
I had accidentally set the channel 7 option to store waypoints and on the radio my timer switch also was triggering ch 7 ...
So every time I switched on the timer the new waypoint at zero alt. and @home pos overwrote my stored wp:s
Michael Pls check if this is your problem as well...

AUTO Problem solved.jpg
Hi!
I have the same problem with my hex and 2.9.1.
Hovers at half throttle and climbs like a rocket at full throttle so no performance issue...
Altitude hold perfect, within 1 m, also when flying around at reasonable speeds
Loiters perfectly, (incredibly well.... within 50 cm...)
RTL works ok climbs to default alt 50 m, flies home and descending
Next test navigate...Then problems started
Tried a lot of different missions
examples:
Mission with 4 wp @50 meter alt.
AUTO in air =starts descending slowly from the current position.
(once it flew wp 1 and 2 then descending at wp2 without proceeding to 3 and 4)
Tried mission with auto takeoff and autoland
AUTO takeoff = climbs a couple of meters then descending slowly
Have Arduplane in a fixwing and it navigates perfectly.
I´m running out of ideas...
Need help!
Regards

Desperation BUMP
What height was your waypoint?
