According to Randy the know issue of altitude loss after a high speed run is at its heart a frame issue.This seems to me a very worthwhile discussion to have.Once the majority of us understand this,…Continue
"After a few false starts, I can verify that the Zubax GNSS 2 modules work great with the latest firmware for the PixHawk (3.4rc1). I had been using the Pixhack, but it does not support UAVCAN. I switched to a PixHawk, but received a clone which did…"
"I had a similar problem once. The cause was the GPS, it was one of the ones mounted on a circuit board with out a clear way a identifying correct orientation. I was 90* off and upside down and had the symptoms you are describing.
"it also has a lot to do with your thr_min and thr_mid parameters, set thr_min to the lowest possible setting which will spin your motors, than adjust thr_mid accordingly. I think what it does it increases the resolution of the PWM signal, so…"
"I think it's all of the above. I added a plexi glass cover over my pixhawk and it instantly solved the problem so it's definitely not just aerodynamics but air pressure. After all it uses a barometer that can detect the difference in…"
I was looking for the explanation of altitude loss when moving copter horizontally forward (and other directions) - but I never found a simplest explanation. When the craft is moving forward it is leaning towards the front (pitch)…"
"Emin, The Zubax unit looks awesome, but then so is the price - dearer than the most expensive pixhawk clone I ever bought (and that was with all the accessories!). As for the GLB link you posted here, I am not certain that this unit is i2c…"
"I have an update on the Gill static pressure port 3D model. I've continued to work on the design and manufacture. At this point I believe that I have a feasible, cost-effective solution. The 3D print house, Shapeways offers relatively high…"
"Randy, I've been flying 3.4 today on my sawn-off (330mm) Turnigy Talon v2 framed quad (with AUAV-X2) and I must say it flies beautifully. With the external Baro, I get a much smoother lift off in AltHold than with 3.3.3 (with internal baro),…"
