We completed the last flights for today. I can say, we are back in the air!
Setting the gier integral value to zero worked wonder! Everything is back to normal and as long as you do not make too great movements with the sticks everything works fine.
It seems that the new software version 3.12 has problems with large stick movements so I switched on the "Specky-Bit" which reduces nick and roll signal to half the normal maximum.
Today I was able to complete my testflights without loosing a propeller!
Now watch my newest testflights:
Get the Flash Plugin to see this movie.
As you can see it's stable enough again to try some outdoor flights. Sadly the weather seems to play bad and we hope to be able to fly outside to the end of the week.
Now that our UAVP fly again, eventually we can try to work on the software. I have several ideas I would like to try to implement. Attitude stabilization, coordinate translations using the compass, throttle adjustments and special throttle courves, GPS support, it all should be possible...
It flies again!!
I really like the idea of Altitude stabilization. Ideally, It should just "stay in place" until you tell it to do something. I understand the gyroscope, but how do you sense the altitude change.
I am looking up parts now to start building mine. I am thinking of doing it completely from scratch. Software and all. Not quite sure yet, any suggestions?

Welcome back Kevin!
Now, attitude stabilization can be done with a barometric sensor. There is another UAVP out there called Mikrokopter which already does support a barometric sensor. I wrote a blog entry about this here.
Our UAVP currently does no attitude stabilisation. We could try to do it using the linear acceleration sensor we have on-board, but current experiments trying this were not really successful until now.
Considering starting from scratch I can tell you it's prossible. A friend of mine did it and created his own board. later he ported a Pitchu-Code to his design.
I would advice to take a powerfull processor from the beginning. Go for an ARM or something like that. You can't have enough CPU power.
Good Luck!
