The file extension changed with Arduino 1.0

You also get this message if the board is not responding - e.g. has no power or the TX/RX pins switched or the reset pressed at the wrong moment.

Video is private. Can't see it.
Did you program the ESCs to min. and max.?

Still guessing:
Cycle Time is too low. Should be about 6000.
CAM1 is low.
Pitch is not about 1500.
There could be problem with the Wii-gyro or the I2C.

Maybe vibrations to the gyro? Just a wild guess - I have no idea.

Calibrating the ACC: Had the same effect today. Took ages so I cut the power.
The fourth time it calibrated in about 5 seconds - as in 1.8.2

Could you post a screenshot of the GUI?
Sounds to me like a problem with the sensors.

As always:
Did you set up the ESC and TX correctly? Low: 1000, Hi: 2000
Timing to high?
Did you calibrate the ACC?

Hello! I'm just coming back from flying latest 1.9 First takeoff and it's really nice to fly. Absolutely stable in ACC-mode (WII+NC). Then I accidentally hit the ground (not very hard) and continued flying. The quad began to drift away to one side. Had to compensate it with the sticks but it was get...

At the moment I'm powering my quad from one 2A BEC.
FC, RX and 2 Servos for camera Pan & Tilt. Works quite well.
5V @ 2A are more then enough for that.
I see no problem using a separate BEC for the servos.

The spec of the Arduino says 9V max. At least on the plain Mini I'm using.
You would get a problem with 13V on the servos for the camera pan and tilt.

If you want to power the FC direct from the LiPo use a 7805 power-regulator.
They are quite cheap. I'm thinking of doing so in the near future.

Nice FC. Did it almost the same way.
Used an Arduino Mini.
BTW: Do only connect 1x ESC to supply 5V and leave the others unconnected.

Shouldn't it be 3S?
I tried to fly a 2S - way to slow.

Hello! Today I tried 1.9pre. It definitely has a drift issue in level mode. Drifts to one side and you have to pull against it until the stick is at outer stop. In the GUI I can see the lines of the ACC constantly moving a little bit even if the Quad is laying on the table. That's not happening with...

You shoud try to set "#define MINTHROTTLE 1150" a little bit higher.
Looks to me, that the ESC are running the motors to slow.
