Quad won't fly to Waypoints - only turns towards them

Started Aug 30, 2013 0 Replies

I tried waypoint nav yesterday and my quad would not fly to the waypoints.I could hear the planner going through the waypoints and see it turn towards each one in turn, but it never flew to the…Continue

Arducopter Level Procedure

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…Continue

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?Continue

"I've considered making a more or less disposable pod out of blue foam, which is easy to carve, light, and very cheap.  Aside from this (which I haven't yet seen anyone do), the only other option seems to be taller landing gear."

Quad won't fly to Waypoints - only turns towards them

I tried waypoint nav yesterday and my quad would not fly to the waypoints.I could hear the planner going through the waypoints and see it turn towards each one in turn, but it never flew to the waypoint.It was a very small area, and I eventually set the waypoint "hit" circle down to 3m, but still no luck.Params and log attached - any suggestions?BTW Loiter and Alt Hold works great.See More

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.…"

"Hello, the perfect 90° is not really necessary. What is important is that it has to be still because during calibration it make a set of readings and if they differ a lot you could have bad calibration values. Also order of placement is not…"

Arducopter Level Procedure

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 I get it perfectly 90 degrees to the horizontal in both axes?  Or is as near as I can judge, good enough?I obviously try to get it as close as possible, but I am bound to be a bit out.See More

Etienne replied to Alexey Kozin's discussion its realy problem or "chain letter"/fake ? in the group ArduPlane User Group
"Thanks for the replies.  That sounds about what I had in mind.  I think it's better to power the airspeed sensor from the APM as it probably uses the internal voltage to do it's airspeed calculations and this assumes the airspeed…"
