APM2 - fails to detect/use Micro-SD "no dataflash inserted"
My APM2 says "no dataflash inserted" when in terminal.
does it need some sort of formatting or anything else to be recognized ?

Does UDP work on today's Mission Planner ? (please confirm-my stopped working)
Today, I cannot longer use UDP - don't know why (worked yesterday)
updated to 1.1.72 - and it does no longer work.

Imagine this:
RTL altitude is set to 100m (dafault)
You fly over higher terrain (150m) - then need RTL.
RTL would now fly into terrain.
Maybe we should not descend until xxx maters from home ?
What would be a nice solution to this problem - provided that
Read more…Altitude not properly reset at startup.
I booted APM - now with stock Plane 2.33 firmware - but this problem existed for a very long time.
Altitude = 0 (real altitude is less than 20meters.)
waited for GPS fix.for several minutes.
Altitude is now 82 meters. (the moment that GPS got fix.)

Once I calibrated compass - how/when would I recalibrate it ? or is it only done once per hardware configuration ?
Would a recalibration be needed when flying on a new site, or after some time ?

It would be *very* sweet if Mission Planner could be compiled for Android, to run on a phone or pad, would be fantastic, and extremely useful for field-tuning.

I have no luck flying at preset altitude , or RTL at set altitude when airspeed is enabled.
By looking at the source, I am not even sure it it's expected to happen:
static void calc_nav_pitch()
{
// Calculate the Pitch of the plane
// ------------------
nav Pitch alt PID /vs/ nav pitch as PID ? are they used together or what ?
is *only* "Nav pitch alt PID" used when airspeed is not available ?
and
is *only* "Nav pitch AS PID" used when airspeed is available ?
Or is there any way these two are used together, or influence each other ?

RTL comes home at right altitude. FBW-A flies nice. so PID's ire not too bad.
When in AUTO, AP applies negative pitch, and would hit terrain.

I see in the log that targetalt = 103 and targ

I'd like to save "level" just like multirotor - to be able to boot up APM at any angle, instead of having to level up the plane before each boot.
how can that be done ?
Read more…Please help:Auto mode fails to fly to next WP (screenshots attached)
Please see the strange behavior as the plane goes away from the next waypoint, instead if trying to reach it . (the wind may cause it to turn extra fast, but the PID's are fine enough for a reliable RTL from any direction)
What's wrong ?

Is there any chance, it will manage to b

I's like to add some code to:
