Setup tips and questions (Trex 450)

Started this discussion. Last reply by Christoph Oct 15, 2011. 5 Replies

Dear all, I am planning to try out arducopter with a flybar Trex 450 to gain first experience with the hard- and software.My setup thoughts so far:- will use my 401 gyro with heading hold and plan to…Continue

Loading code with MP works, but prompt line still shows former code version

I just got my APM two weeks ago.Read though all the wiki and loaded the arducopter code 2.0.39 beta. It was the code which was available at that time through the mission planer.Now the latest one is…Continue

Christoph replied to Dale Greer's discussion Will solution for Texas heat upset the barometer? in the group IRIS
"Can you read out the temperature from your log? Somewhere in the the barometer values there is a parameter baro temp. I would be interested in what that says in case of your flights."

"In addition. After I build up confidence, I started checking out the fail safe modes. In real conditions. Switching off the transmitter, simulating loss of signal during a mission and during position hold mode. Guess what. Works fine. No crash,…"

Christoph replied to Justin M's discussion 3DR Iris Screwed Me Again! in the group IRIS
"Hi Justin, post your logs and we will have a look at them. There is something wrong with your soft- or hardware. My best guess is if you don't replace some of the components or software you might have troubles again and again. It won't…"

Christoph replied to Christoph's discussion Happy new IRIS+ pilot in the group IRIS
"Do you know what exactly the difference is between the yaw management in stable mode vs. loiter/pos.hold? I guess in GPS modes the heading of the GPS will be taken into account which then leads to those twitches, which we see less in stab mode? I…"

Christoph replied to Christoph's discussion Happy new IRIS+ pilot in the group IRIS
"I forgot to update on the 433 Mhz telemetry. Had some issues with the range in the beginning. In the meantime it turned out that it was mainly due to the reduced output of less than 10 mW, which was the standard setup. Turning it up to max of 100 mW…"

Christoph replied to Christoph's discussion Happy new IRIS+ pilot in the group IRIS
"Ok. Will try stable mode as well. But I like actually the position hold to get better moves when i.e. climbing up. I guess there is a way to activate pos. hold with a manual yaw like in stabilize. That could then be another simle way to get improved…"

Gregg replied to Christoph's discussion Happy new IRIS+ pilot in the group IRIS
"I have the same problem with my Iris and the x8. quick little yaw movements in loiter mode. My only cure was to ditch the tarot 2 axis gimble and install the DYS 3 axis gimble. Basically direct plug n play, but I found some gimble settings on you…"

"Update: Still happy with it. In the meantime I installed the Tarot Gimbal.Today I tried out some failsafes in real life condition.Switched the transmitter off during an auto mission. The Iris+ did as she was supposed to - continue the mission.I also…"

"Isn't there a log for the temperature? Under Baro there is a point Temp. I checked one of my log files and it reads temperatures between 38 when powering up and around 45 after the flight. Doesn't look concerning."

"And if overheating would be a serious issue, I would be keen in knowing it. I am flying in a hot and humid environment. So far only two battery packs in a row, without issues."

Christoph replied to Justin M's discussion 3DR Iris Screwed Me Again! in the group IRIS
"Does anybody knows how to interpret the fact that the RCout to the ESC went down? Will the log show such behaviour in case the ESC overheats? My best guess would be if the RCout signal goes down, it's coming from pixhawk, thus from the software."

Christoph replied to Mhct's discussion Iris+ sudden fall in the group IRIS
"Hopefully anyone with more experience in log reading will have a look and tell us what might have happened. Would be good to know what the signs are in case an ESC or motor fails versus the arducopter produces faulty output signals."

Christoph replied to Mhct's discussion Iris+ sudden fall in the group IRIS
"It seems scary but the point is to figure out what happened. I believe in the majority of cases something went wrong which could have been prevented. Like in above case. As said I am not an expert in log analysing but here it rather looks like the…"
