"R_J,
Thanks for the recap!
I agree that our problem looks to be of the GPS kind.
We had a crash last week that looks almost like the altitude problem but we weren't accelerating. We were doing a Auto Takeoff, the quad got almost…"

Hard Roll then Crash in Auto

Hi All! We were flying some auto missions today (takeoff, waypoint, waypoint, RTL) and all was going well. Until we went to takeoff the quad got to the desired height (10m) it rolled (about 60…Continue

Hi All,I was testing the Auto Commands for ArduCopter 2.9.1 using APM 2.5 with MTK GPS and something strange happened. I had been doing successful auto flights (takeoff, waypoint, RTL) for about a…Continue

R J Hamlett replied to Jake Simon's discussion Some Auto Questions/Problems"I think there are about four separate problems that all appeared with 2.9.1. For some fixes have since been found, and for other the 'jury is out'.
Now the first real 'killer' one, is the compass automatic calibration. Something…"
Jake Simon replied to Jake Simon's discussion Some Auto Questions/Problems"R_J,
I have been keeping up (kinda) with that discussion but I thought that we had avoided that problem because we had no problems hovering. Also, after the almost fly off it would RTL to within 2m of its takeoff.
Does this still sound like…"

Hi All! We were flying some auto missions today (takeoff, waypoint, waypoint, RTL) and all was going well. Until we went to takeoff the quad got to the desired height (10m) it rolled (about 60 degrees) and then started to descend hard.It had a hard landing, flipped over, and broke an arm. We had something like this happened before and it was an ESC. So we took off the propellers and ran the motors while moving the ESCs around. We saw nothing out of the normal. We are flying a DJI F450 with…See More
R J Hamlett replied to Jake Simon's discussion Some Auto Questions/Problems"If you search the forum, the 'somewhere else' behaviour is well reported...
Apparently there were some significant changes to the handling of the Mediatek GPS with 2.9.1, and it results in spurious readings being accepted. The explanation…"

Hi All! I'm working on a research project and we're going through the all the Auto commands for ArduCopter 2.9.1b and we have some questions. Does the parameters hit rad and yaw for WAYPOINT do anything? We have tested them but can't seem to find any effect.Does the altitude for ROI do anything? Again, we tested it and it didn't do anything.Does CW/CCW and rel/abs do anything for CONDITION_YAW? It always turned CW even if we set it to CCW and it always turns to the absolute heading, never the…See More
Jake Simon replied to Bill Patterson's discussion Can someone explain ROI a little bit?"To get ROI to work set the parameter YAW_OVR_BEHAVE to 1 in the advanced parameter list. This will keep the copter yawed toward the ROI GPS points for all waypoints (doesn't work for RTL). Also, I don't think that the alt parameter in…"
Jake Simon replied to Tomas Soedergren's discussion Questions about Hit Rad and some parameters"Been working on hit rad and yaw parameters for waypoints and we haven't found anything different from Tom's observations: hit rad and yaw have little to no effect on the mission.
It would been helpful to know if these parameters actually…"
Jake Simon replied to Ran Talbott's discussion 2.8.1 or 2.9.1 for fully autonomous flying?"Ran,
I've flown some auto missions on 2.8.1 but most of them have been with 2.9.1b. I can tell you that 98% of the time we have had no significant problems with 2.9.1b.
But, there was a time when the GPS suddenly thought it was about 250m from…"
Jake Simon replied to Jake Simon's discussion Motor Cut Out Then Crash"Gary,
Our problem wasn't from a bad connection between bullet connectors but from the bullet socket on the ESC board breaking its solder pad. When we took the heat shrink (that DJI puts on) off the ESC this socket just fell off the…"
Wiki NinjaGary McCray replied to Jake Simon's discussion Motor Cut Out Then Crash
"Bullet connector caused crashes have been a continuously recurring problem on this site.
I've got two FlameWheels with DJI OPTO ESC's and have never had a problem.

Jake Simon replied to Jake Simon's discussion Motor Cut Out Then Crash"SOLVED!
As Dave_C wrote, it was a loose ESC connection. One of the female bullet connectors on the ESC wasn't connected to the ESC and was being held on by the shrink wrap.
Replaced the ESC and just had a bunch of…"

Jake Simon replied to Jake Simon's discussion Motor Cut Out Then Crash"I have DJI 920 Kv motors connected to the DJI ESCs. Been flying (and crashing) the same setup for a while and the bullet connectors always seemed to have a really tight connection.
How would I test the motor/ESC connection without flying? Do I…"
Jake Simon replied to Jake Simon's discussion Recording Voltage"Thanks for the info RJ!
Any idea if .log is formatted the same as the .tlog?
I wrote part of a program to extract information from the .tlog format and I'm wondering if I can use it for .log files as well.
-Jake"
R J Hamlett replied to Jake Simon's discussion Recording Voltage"Just to fractionally 'expand'.
On the logs enabled listing it is 'CURRENT' (full word).
On the log name column, it is "CURR" (two R's)
To enable, it is "CUR" (just one R).
Insanely 'non…"
