Frank Al replied to Frank Al's discussion Balancing propellors and motors
"Hi Richard,
Thanks for your message. Actually I don't follow this post any more since I stopped flying drones. By coincidence I found the message about your post :-)
To answer your question, the files are not downloadable indeed. Did you know the…"

Frank Al replied to Chris Mitchell's discussion Can quadcopter motors be mounted upside down ?
"Well, I actually fly one of my R&D quads without c-clips all the time. The magnetic force is huge, especially when power is applied. Full power only moves the outer part about half a millimeter. Never have encountered a 'fly-away' of the prop, only…"

Frank Al replied to Randy's discussion ArduCopter-3.2 beta testing
"Thanks for your replies Randy. I'm using the same version of MP. Meanwhile I did several reboots and till so far 3 distinctive values are reported for COMPASS_DEV_ID2.
So let's wait a while for other reports.
If you need me to do any additional…"

Frank Al replied to Randy's discussion ArduCopter-3.2 beta testing
"The end is missing from my previous reply
So, when I change COMPASS_DEV_ID2 back to the value right after compass calibration, all is fine and no pre-arming warnings any more. I guess it's not very convenient to do this after every reboot, so I…"

"More investigations..Somewhere further on this thread I read Randy's comment about the software checking the compasses id's in order to detect a changed one. This made me redo the compass calibration dance, but FIRST zero the two compass-id's in the…"

"Hi Devs,
Testing 3.2rc3 I can't manage to arm the quad because of "PreArm: Compass not calibrated" showing up in MP (v1.3.7).
I ran the manual calibration several times, but to no avail.
I have a PX4 FMU+IO flying really perfect on 3.1.2
Quad, X,…"

"Andy, did this work for you? I'm also having issues with altitude on PX4/PX4IO, even in 3.2-latest of june 11th. My report is on page 37 of this thread. In EKF-mode the altitude sticks at 15000 meters after a few minutes and in 'legacy'-(non-EKF)…"

Frank Al replied to Randy's discussion ArduCopter-3.2 beta testing
"Tried 3.2-rc2 on my quad today (PX4 + PX4IO). There's a problem determining the altitude of the quad. When I enable EKF the reported altitude is 15000 and when I disable EKF the altitude remains at a steady 0. Even after waiting 10 minutes this…"

"Yes that's right, the propeller needs to break the beam between the IR diode and the CNY70 sensor."

Frank Al left a comment for A Stanley
"Hi Stanley, you can use this scheme for that. It's the same I'm using currently and based on the reflective IR send/receiver CNY70. You can use the reflective property for balancing the motor only by using a paper ribbon with a black dot on it…"

Frank Al replied to Rob_Lefebvre's discussion Anybody flying PX4?
"Rob, as far as I can see in one of my recent RC7 logfiles (attached), I don't see glitches (do you?), all motors sound well.
I'm using a Futaba R-118F 40Mhz receiver. This one is not providing PPM out-of-the-box, however it's available inside the…"

Frank Al replied to Randy's discussion ArduCopter-3.0.1 released!
"Finally a nice day in Holland: no wind so a perfect day to try out RC6 and out of curiosity, the autotune feature. I can only say it's perfect. Flight modes tested: stab, alt hold, loiter, rtl and auto. When I load the KMZ from an auto mission into…"

Frank Al replied to Jan Willem's discussion DO_SET_ROI / ROI : Howto use this option?
"Today I tried the ROI and noticed the same as you: after the first waypoint it behaves following the setting of param "WP_YAW_BEHAVIOR".
So what did I do...I manually inserted the same roi-command before each waypoint. You just save your mission to…"

Hi,When I try to download a log from my PX4 or use the .bin->.log button the decimal numbers in the .log file are constructed using the decimal separator from the local Windows settings. Trying to load the .log for viewing in MP gives me very weird…

Frank Al replied to John Mulligan's discussion Px4 Testing
"Hi all,
I just recently upgraded from my APM1 to PX4FMU+PX4IO. I experienced no issues installing firmware, as long as I use the Qupdate program. No success yet with MP.
After all firmware is installed (FMU and IO) the board connects to MP without…"
