Pierre replied to Randy's discussion ArduCopter-3.2 beta testing
"Thanks for looking Willy.
Actually it starts falling at line 8850 and hit the ground at line 9000, I had all the 9 sats during the crash. It's only in the wheat field that it has lost satellites. 
We already discuss the idle ThrIn…"

Pierre replied to Randy's discussion ArduCopter-3.2 beta testing
"Nop, my failsafe is configured to engage RTL flight mode only. With the exact same failsafe configuration I never had any issue like this with 3.1. When getting close from my radio range (~1,5km, here I was at 500m) I am used to have a short RTL and…"

Pierre replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi guys,
I just returned from a 3h mission of research in a wheat field... I was testing 3.2rc1 release, nicely cruising at 60m high in drift mode when the RTL engaged (was not supposed to) and the copter fall like a rock !
Finally found the copter…"

Pierre replied to Gábor Zoltán's discussion Adding extra functions to MinimOSD
"Hi Miguel,
Yes, current efficiency seems to work fine, even if I would not like to rely on the last minutes as the estimation is based on theoretical battery capacity and current sensor calibration.
I will be more than happy to test a new "Distance…"

"Here is a video with MinimOSD 2.4 r785, which runs trouble free :)


About some improvement suggestions : it would be awesome to have an other efficiency indicator, which would allow to have an idea of the remaining distance that can be performed…"

"Hi Gabor and Vilnis,

I also had the altitude reset during flight issue. Since I put the release 750 I have not seen the problem appears. Still have to perform more test because it seems to be very random.
However, as the last video of Vilnis, the…"

"Hello,
I re-tested the autotune on my quad:
- qav400 with hard mount gimbal in front- 8x5 @ 1000kV - 3 Ah @ 4S - 1.6 kg AUW 
Here is what I got after a successful autotune :
RATE_PIT_D 0,015

Pierre replied to Pierre's discussion AC3.1.2 Baro alt reset in middle of flight (Video)
"Yep, exact same problem. Which version of the OSD are you running ? I try to update to minimosd extra 2.4 but the problem remains.
I noticed that the problem often appeared after a fast climb followed by a alt hold, during some kind of "zero…"

Hello,I have a problem with my setup: frequently, the barometric altitude resets to zero randomly in flight. Fortunately it does not lead to crash but I'm worried in case of RTL.This is an APM2.5 controller, which runs AC3.1.2 with a mavlink extra…

"Hi,

I am having troubles with a new MinimOSD card : when the copter sits on ground everything is working great but as soon as I take off, the OSD overlay start to blink badly and randomly. Camera picture on the backgroud remains stable. Does anyone…"

Pierre replied to Randy's discussion AC-3.1 autotune support discussion
"Hi,
I gave another try to Auto Tune with rc7 and this time it failed. The roll axis tuning seems to be fine but pitch axis failed on the first step of calibration. From the log it looks like it hit the bottom limit of rate_p (0.02) on this…"

Pierre replied to Randy's discussion AC-3.1 autotune support discussion
"Hi,
I give a try to ArduCopter3.1rc7 AutoTune today and I am not very pleased with the tuning result.
When I do some aggressive flights (full throttle), it feels like I hit the redline off a combustion engine and engage the rev limiter.
Which value…"
