Jesper Rooth replied to Henrik Holmberg's discussion Phoenix 2000 RC Glider
"This thread deserves an answer. :) I have been playing around with APM for years and just got my Phoenix 2000 in the air.
Answer to your question is no. It is not a good UAV. Fuselage is way too tight. Go with a Skywalker instead. Or Bixler if you…"

Jesper Rooth commented on Melih Karakelle's blog post OpenBee: an OpenSource Telemetry Module with Xbee footprint
"Nice work! Are there any benefits for us already running OpenLRS TX/RX's? Will this device improve the telemetry performance and if so - will it work together with OpenLRS since both are working on the 433 MHz band."

Jesper Rooth replied to Jesper Rooth's discussion Failsafe and OpenLRS
"Fixed.
Changed the code on the OpenLRS RX so it only changes channel 3 (throttle) to the saved failsafe value. Works fine now."

"OK. Tried that already since I always clear logs after each flight. But problem seems to go away when I downgrade to 2.50. Then all logs get in the right order and can be downloaded. Hmmm.."

"Would CLI setup/erase/reset also reset the datalogging memory? I have wierd logging now with logs have higher start numbers than stop."

"Hmm. Last couple of flights I have not even been able to download the logs. I cleared everything before flight to be sure.Get this text when trying to "Download All Logs" in Mission Planner.

Jesper Rooth replied to Todd Nelson's discussion APM 2.0 Ardupilot 2.50 failsafe setup
"Hi
Even though I have problems now this is how I got it to with on my Futaba.Your PPM value seem ok but verify that THR_FS_VALUE is set. Should be higher than your 911 uS. Also verify that THR_FAILSAFE is set to 1.
If you fly in the lower modes such…"

HiGot failsafe to work perfectly with my Futaba 7C and 617FS. At signal loss it circled for 20 seconds and then come back in RTL-mode.But now I switched to OpenLRS and cannot get the thing to work. I have configured failsafe on the OpenLRS RX so it…

"What is the maximum time Arduplane can log? Yesterday my plane got caught in a tree and it took four hours to get it down - using a chainsaw.
When loading the logs I got "Bad log number" from 2 files och the working log only contained 37 minutes.…"

"Hi again

I noticed that the first couple 100 lines in the log shows a predefined GPS altitude of 137 meters. This is before I get a GPS lock.
GPS: 29689583, 0, 6, 0.0000000, 0.0000000, 0, 0.0000, 137.0000, 0.0000, 0.0000ATT: 37, 30,…"

HiWhile analyzing my logs I noticed that there is a quite big difference between MixAlt and GPSAlt. Is this normal or can it affect the performance of my flights? I always had a wierd problem with my platform were it sometimes wants to "kill itself"…
