Please tell us a bit about your UAV interest

Just for fun. I used to have a tricopter using KK+5.5e board. Now I have a quad using APM2.

"Hi all,
I just upgraded to 3.0.1. Mine is an APM2. I do not have any current sensor. Frame is F450, using the stock PDB. APM2 sits on the upper board. 4s4000 lipo is strapped under the bottom board.
Well I did the compassmot, and repeated a few time…"

With the advancement of firmware, (2.9.1), is it OK if I don't launch / arm from a horizontal attitude?I use a DJI F450 frame, so the APM2 sits on the top plate, and my 4S 4000mAh lipo pack has to be strapped to the bottom, resulting in the quad act…

"Related questions about declination.
How precisely correct does declination need to be for the simple-mode and GPS features to work reasonably well?
For example, is being correct to within 1 degree good enough? Or does it matter to make it correct t…"

RedPalm replied to Don Fiedler's discussion Unexpected motor glitches (speed up) with Tri Hex and Octo APM 2 & APM 2.5 using 2.73
"For me, the random ESC blips (very brief duration pulses) clearly do stop occurring when I give CH6 a low value, and they are easily reproducible when I flip a 2-pos switch on my TX to give APM2-CH6 a high value.

However, I now have a new problem.…"

"Now that Arducopter 2.81 is out, I decided to take this chance to document the glitching again on 2.73, then upgrade to 2.81, then check for glitching again, for the sake of comparison.
Unfortunately, (by my unscientific tests), the glitching proble…"

"Hi, I have the intermittent ESC blips on my APM2 (on current quad firmware 2.7.3) too.
They are quite easy to reproduce during low throttle, (make small cyclic stick movements esp. with roll&elev together, i.e. diagonals.) and seem to almost never h…"
