Hi Tridge
Awesome work with the new version, blheli pass-through updates are especially welcome.
I am having some trouble with getting the DO_VTOL_TRANSITION way-points to work properly though, when I program a transition from fixed wing to mc, the aircraft does a very aggressive stop before hovering back towards the previous way point.
Tlog here so you can see exactly what I mean https://drive.google.com/file/d/1B_uyg_347tCGKlTB_gRE7Kr-EBryIWBa/view?usp=sharing
Ok found ! Arming require to 2 solve the problem. Forgot to adjust rc3 min and trim properly but reverse thrust was rewrite ? Ch3 percent output looks different !
Reverse -100 to 0 = 0 to 50%
Normal 0 to 100 = 50 to 100%
I’ve now released 3.9.1beta2. This is a the second beta for the 3.9.1 release, which is a minor update over 3.9.0. This release includes the following changes:
increased default buffer sizes in dataflash for some boards
fixed a bug with small dataflash buffers
updated OSD with new items: hdop, temperature, waypoint, xtrack, flight distance, flighttime, efficiency (thanks to Hwurzburg, vierfuffzig and sh83).
reduced memory usage in serial buffers
adjusted some default parameters to give a better first flight experience for more users.
The default parameter changes are:
RLL2SRV_P from 0.6 to 1.0
RLL2SRV_I from 0.1 to 0.3
RLL2SRV_D from 0.02 to 0.08
PTCH2SRV_P from 0.6 to 1.0
PTCH2SRV_I from 0.1 to 0.3
PTCH2SRV_D from 0.02 to 0.08
TECS_PITCH_MAX from 0 to 15
NAVL1_PERIOD from 20 to 17
The PID parameter changes won’t affect anyone who has done some tuning, but will make the first flight experience for a new user be alot better for nearly all aircraft. Paul and I decided on the values based on experience with users flight logs, plus the experience users have had with AUTOTUNE mode.
Cannot arm in 3.9b2 because the Bad Logging error.
Omnibus F4 PRO V3
Terrain Disabled.
LOG_BACKEND_TYPE=1
LOG_BITMASK =65535
LOG_FILE_BUFSIZE=4
Reformat SD with 2 passes
“It is the new loiter controller from Leonard, inherited from the copter code. It does a better job of smoothing out transitions, as well as providing better pilot control in QLOITER mode.”
Hey @tridge I dropped 3.9.1 beta2 on a pixhawk1 last night and noticed it overwrote my PIDs to the new defaults from what they were before. I thought this was only supposed to happen when it was a fresh install? Did I misunderstand?
edit: Disregard, it looks like my PIDs got reset to default sometime ago. I wonder if this happened during 3.9.0 beta testing. I have no way to verify because logs prior to that got wiped, so, let’s just not worry about it.
