"Good Morning, just found out that the internal compass was 60° off from actual heading. Now looks a lot better. For my understanding (although have read a lot about it): P = correction angle I= how fast it will rotate D=? and what will I see…"

"It's hard to answer your vibration damping question, as I have never found anything that worked well on my heli.  I played around with rubber tube dampers like this which are home-made: I think these have the potential to work very…"

Wolfgang Feichtner replied to Gisela & Joe Noci's discussion Optimizing Wing Aerofoil for UAV long range flight ( not for endurance)
"May I point out one wrong assumption at the very beginning of the discussion: It is not speed what makes the ride less bumpy - it is the wing load!   b.r. Wolfgang and it always suprises me how good the Clarks perform in reality compared to the…"

Wolfgang Feichtner replied to Tom Shaw's discussion Solar powered photography platform - flying wing
"High Tom Unfortunately not very realistic thoughts you are starting your project with. Why: Your design must be super efficent to be powered by solar panels. So first thing forget about the EDF´s. they are the biggest known power wastes known…"

"I really recommend you learn to use the system on a small cheap helicopter first.  A big part of the challenge with flying with it, is that the user must understand how it works.  Once you are comfortable with the setup, and flying, it…"

"Wolfgang, this is a really difficult question to answer.  I think that the system can fly the big helicopter, and it will probably work well.  It's just such a big and powerful, and expensive machine, I hesitate to recommend…"

Good Evening Gents,just a little offending question: :) Is the arducopter software and hardware already in a state to be built in a heavy gas chopper? In my case a Vario Benzin Trainer with 1800 mm span and 7 kg weight powered by a 23 ccm Zenoah.I am not afraid about the settings in arducopter, as this ship is very stable without any electronic help besides the aft end. In my mind just came up another one, this one for the developers:Read the manuals of the wookong guys (hope I tipped enough…See More

DeveloperAndrew Tridgell replied to Wolfgang Feichtner's discussion Erratic Horizon with speed sensor
"Don't do that!! Setting AHRS_GPS_USE to zero means you won't use the GPS for navigation at all. The plane will only use dead reckoning. Yes, it will stop it 'jittering' on the ground, but it will also make it fly off into the…"
