Etienne replied to Wolfgang Feichtner's discussion Loiter circling
"I had the same issue, turns out it was LOITER_LAT_I and LOITER_LON_I
I set them to zero (I think they are completely hidden with the latest Planner - check in advanced params).
Once you have set I and D to zero, lower the P and try again.  Maybe…"

I have a question about the level procedure:Since my AP is not that easily removed from my frame, how perfectly square should I hold the 'copter in the various attitudes?For example, when it says hold the APM on it's left side, is it important that…

Etienne replied to Wessie's discussion Arducopter 3.X PID settings
"Probably statiing the very obvious here - but sometimes one does not know about the obvious if it hasn't been pointed out!
Also not sure how up to date it is, nor how close to "plain english"…"

Does anyone have any suggestions on protecting camera gear slung under my quad copter?  Is sturdy landing gear the best one can do?Any tips/suggestions?

Etienne replied to Alexey Kozin's discussion its realy problem or "chain letter"/fake ? in ArduPlane User Group
"Just to be clear, if I leave JP1 open and I power both the input and output from my BEC, then this should not be a problem?  Or are the IO pins and telemetry radio still powered through this diode?

Alternatively, I can cut the telemetry radio…"

Etienne replied to Ashley Belbin's discussion APM 2.5 in South African DIY Drones User Group
"Ashley, I live in Garsfontein, in Pretoria.  Though my kit is not exactly the same as yours, I have pretty much the same stuff and should be able to help you.  I will send my contact details to you."

Etienne commented on John Arne Birkeland's blog post Autodesk PhotoFly 2 - Automatic 2D to 3D conversion
"Agisoft's Photoscan software does this type of thing and works really well with aerial mapping and 3d terrain model generation.  I was recently in the fortunate position to test it's results against a 4mm accurate Leica GPS (using differentially…"

My Ardupilot 2.5 board experienced a fairly hard crash in my plane.  I can see that the board is physically bent near the USB port (very slightly, but visible nevertheless).When I connect to the APM, it does not see the dataflash card.  When I press…

I recently upgraded my Turnigy 9x radio with the FR-SKY DHT-U radio module. This upgrade gave me access to quite a bit of extra functionality, telemetry, range check and fail-safe. Stuff you don't have with the stock radio.The 9x doesn't usually…

I have written a small Java program that uses the Telemetry logs to automatically reject photos that were taken at high bank angles.I was hoping to get better time resolution with the on-board logs and want to enable the software to use either the…

Etienne replied to Paul's discussion Alt hold PID - Tried everything I can think of in South African DIY Drones User Group
"Do you have telemetry on the quad?  Can you see whether the APM "sees" the correct altitude and that it doesn't fluctuate wildly?  There is no sense in trying to tune altitude hold if the APM works with bad altitude data.  It will stabilize fine, as…"

When I switch on the APM and leave it, it shows zero airspeed after calibration. Then every now and again, the airspeed value will jump up a bit and stay there. It does this going higher and higher.At one stage it showed 50m/s airspeed. At this fake…

My current problem is that the AP uses way too much power to climb, whilst not really climbing effectively.It maintains maximum power, while not pitching up much.  This results in it flying faster than it's target speed, while not really climbing…

Etienne replied to HighUP - Aerial Photography's discussion What Telemetry ? in South African DIY Drones User Group
"That kit is excellent and is what I use.  If you play around with the data rates and output power you can get quite far, though I have never reached it's max range with the settings I use now.

I'll have a look at the ranges that I get, but it's…"

Hi all,If I'm only interested in checking the level of my main batteries, do I really need the voltage and current sensor?  Or is it possible to use a resistor to bring down the voltage to below 5V and then calibrate via parameters to get the…

Etienne replied to Jesse Shaw's discussion Long GPS Fix Time (Ublox LEA6)
"I have exactly the same problem.  Luckily I ordered two APM2.5 kits with these GPSs.  I unpacked the other GPS, plugged it in and it got lock nearly instantly!
So, I'm guessing the other one is bad/dead.  Not sure if I did anything to kill it -…"
