Which 22xx/28xx motors are most efficient for 3S batteries and +/- 10"-11" props? There must be some that outperform the usual crop of cheap eastern outrunners that aren't too exorbitantly expensive?
I (like many others) want to maximize flight time w

I've got an external compass 17cm above my frame, I am getting 1% interference on compassmot. Nearly every other parameter is default set up from scratch. Yet I still get the dreaded 'toiletbowling' on occasion, not every time I go into Loiter but ma

HMC5983 replace HMC5883L temperature compensation triaxial compass
The regular HMC5883L compass has no temperature compensation, is there a benefit to this one for ArduCopter?
It would be great to have pre-saved missions that could be assigned/saved to a mission slot with a single button to activate, i.e. the MP Flight Plan tab thus would have maybe 5 nameable mission buttons under which you could pre-save a mission in eac

Anyone have any suggest

What is the expected or normal behaviour with regards to throttle and elevator trim in altitude control? E.g. if the aircraft is too low, is throttle increase only, use

Suddenly I can't connect to APM2 with the Mission Planner (v1.2.29).
It starts getting params fine but then halts with this:
I have erased and reset to no avail, what's going on??
This is the error from the MP:
Any ideas?
Request for a shortcut key, hotkey or key combination for "Write Params" or "Save" in any tab that has that option available.
e.g., on a Win PC: pressing CTRL + S normally saves any open document.
So with the Mission Planner, while flying/testing, rath

Request for this to be added to the MP please.

Also there are some columns that have no heading so one has no idea of what they are?
