Yes, 2.0 (latest code: 2.011) seems quite stable at this point, and we're very close to taking it out of beta and ending support for 1.x.

Also, you may want to upgrade your MediaTek to firmware 1.6 if you're not already using that.

Yes that was happening for me when I saw the erroneous high altitude issue as well. Stabilize was either 0 throw or max throw.

i think these are 2 separate issues.
1- the stabilize mode malfunction. i got this working correctly after i commented out the battery monitor function, reset via cli.
2- the altitude issue im not able resolve

are you using votlage monitor? i have not installed anything but apm 1.02

I am not using voltage monitor and cycling power to the RC plane solved the problem with the Stabilize mode for me - I have seen this problem w/ the Stabilize mode more than once in my setup.

Guys,

on Saturday i flew at last with success. Stabilization and RTL worked perfect even in really strong wind.

Here is my setup:

aircraft is high-wing, 2m wings span, very stable one.

APM of version 1.02, MTK16, no changes in APM code, except GPS configuration in APM_config.h, no additional sensors, just APM + OILPAN 2.0 + MTK16.

I had no waypoints set yet, just wanted to test stabilization and RTL. Anyway Saturday event wasn't without problems. First flight was terrible - i even didn't try to switch on RTL because stabilization didn't work. After switching on the stabi, airframe started make big waves. It was high enough so i just only guess the elevator went to its max (pulled). After i landed switch off/on, got locked home and flew again, stabilization worked perfect. I had not yet stabilization system installed on my models, but this  works great - no wavering just straight flight.

I flew farther from me (500 meters) then i switched to RTL and aircrat returned to me ;o). I repeated this maneuver 3 times (against the wind, down the wind) and it worked still perfect.

But i had problems with log - the log is enabled but after my flights in the CLI i got unpleasant message from APM - no logs available, even if i the logs enabled (all). I erased and enabled logs bot nothing is recorded. Have somebody hint on it?

Next weekend - i try auto mode and if there will be more free time, i try to load APM 2.011 (or latest one, if there will be more recent).
