vertical climb on selecting stabilize or FBWA

Just been out to maiden my new fx-61 Phantom wing build. First plane I have ever used Ardupilot on (I am experienced with Copter but new to Plane). I have 3.5.2 running on a Pixhawk Lite FC, M8N GPS…Continue

Strange failsafe behaviour on bench - plane v3.5.1

Just setting up my first plane with Pixhawk Lite/plane 3.5 and I am witnessing some rather strange failsafe behaviour whilst the plane is on the bench and disarmed, with no available GPS signal.I am…Continue

Another loss of altitude (in AltHold) post!

Started this discussion. Last reply by Paul Atherton Nov 22, 2015. 1 Reply

I was testing my f330 build today (actually went out to run autotune) with 3.3.2rc2 running on an AUAV-X2. In AltHold I am getting considerable altitude loss in forward motion, even walking pace…Continue

PID help required (video example)

Started this discussion. Last reply by Maury Aug 22, 2015. 12 Replies

OK, so I have some PID tuning to do to resolve an issue I have which is demonstrated in the video (link below). Its a twitch on the roll axis. Just not sure which PID settings to look at. The video…Continue

"Robert, the input to your scripts (even though the sensor is configured for kts in the sensors screen) will still be in m/s you need to do a translation in LUA to scale that to whichever scale you need."

"Robert, Glad you're finding the project interesting. Are you aware of the configuration page which is part of the main lua script? The telemetry script has two screens. When you load it (long press on PAGE button) you see the main telemetry…"

"shvars.speedUnits is set by your units selection on the configuration page (which is the code in confrun.lib), which writes the chosen value to your model config file. Its read back in from the config file when the code is initialised. I think you…"

"Robert, the telemetry sensor is configured for kts as you know (the log file shows the same), but the numeric value on the sensor is actually m/s. The teensy sends in m/s, but if the sensor on the taranis is configured in anything other than kts,…"

"Robert, That is an issue with the wiki (missed removing a bit) since the configuration page took over from the offset.lua mixer script - that was how we used to set the offsets and plane/copter before I rewrote the LUA scripts. Thanks for spotting…"

"Robert, did you follow the sensor setup for airspeed and groundspeed  detailed in the wiki? You need to configure the sensors to be in knots, then on the LUA page you can choose the units of choice for display. In my setup the airspeed on the…"

"By AoA you mean the pitch angle? Or the glide angle? If pitch angle, then I imagine this could be calculated in LUA code from the pitch value displayed by A4 (too complex for a calculated sensor). I've never really paid attention to this sensor…"

"Robert, I'm still trying to figure out what you are doing wrong here. If you can please answer na few questions, this might help: Are you running a Taranis X9 radio? So Taranis X9D Plus for instance? This has been written specifically for…"

Paul Atherton replied to Rolf Blomgren's discussion APM MavLink to FrSky X8R S.Port converter
"Robert, if you have followed the wiki then if you do a sensor discovery, you should see a sensor called simply GPS. You need to do this through a discovery (and not by adding manually into Taranis or through Companion - as neither will work)."

Paul Atherton replied to Rolf Blomgren's discussion APM MavLink to FrSky X8R S.Port converter
"Markus, I never test with logfiles, but instead in companion by entering values in the telemetry simulator screen. Now, if you don't have your model yet configured, then you won't have done a telemetry sensor discovery, and from there…"

Paul Atherton replied to Rolf Blomgren's discussion APM MavLink to FrSky X8R S.Port converter
"Yes Markus, This is all described in the Wiki if you care to read through. You don't need to worry about compiling any new scripts you write, as OpenTx 2.2 takes care of this for you. You simply place the .lua file (your text version of the…"

"Markus, Sorry, but the Telemetry screens have only been created for the Taranis radio, not for the Horus. If anyone out there is a horus lua guru, then would be good to see screens developed for the Horus also. Cheers, Paul"

Profile Information

About Me:
My beginnings were in electrical/mechanical engineering, but ended up as an IT infrastructure engineer (since 1990). English born but Scotland is my true home - been here since 1998. Gadgets have always captured my interest, and RC definitely fits the bill as one of my favourite areas for this. Photography, Snowboarding and MTBing are my other passions.
Please tell us a bit about your UAV interest
I was bought my first RC (toy) quadcopter for Xmas 2014 and have been totally hooked on RC ever since. First DIY build in April 2015 was an f450 flamewheel which soon became a stretched f550 hexa, which I still have (although rarely fly). This was too low powered (and far too flexible)though for what I had in mind so I soon started with a Tarot 680Pro framed hexa build (as a solo/dual operator video platform). For fun I started on a F330 build and quickly realised that the frame was too bendy, so switched to a 330 sized carbon fibre frame - all these copters controlled by arducopter 3.3/3.4 now. This is an awesome community, active and inspiring. I am ever grateful to the people here with their relentless passion for the hobby and willingness to assist (even newbies ;-). Truly top notch!
