Since getting it back from Maxbotix, it's never really worked. It seems to give good readings statically, but when flying, it won't work properly despite efforts with electrical noise and vibration reduction. Now, whether that's the…"
"Not being an expert log analyser myself, I can't help from that side.
However, from the symptoms, it sounds like you might be intermittently losing a motor. Front flip suggests it's perhaps the front motor. One of the common causes of this is a…"

"The sonar is very sensitive. Mine reacts to a wire fence from 2m above. You need to be sure the field of view of the sonar is completely clear of anything, including wires.

However, it seemed to fly OK when you had it in the air for that 4 second period ... until an arm came off.
Seems to me your main problem is the unglued PVC joints. …"
"I tried Alt Hold at about 30 cm yesterday over a flat surface (tennis court). Each time, the quad was unstable and would slowly rise to ~ 75 cm before stabilising.
I haven't looked at the logs yet. However, there is a large amount of prop wash…"
