"Here is my setup: "

"I've recently made one of Tarragona (Catalonia, still in Spain): http://pan0.net/upano.php?id=3788 It's not so glamorous, but it's a 360º aerial panorama ;)"

"My board is ok, I've tested it with this test: http://stuff.storediydrones.com/ArduIMU328_V3_Arduino_Test_Code.zip By the way my board is v3."

"I've the same problem, only roll works, but partially because if I pitch the imu board roll servo also responds to it."

"I agree Harry, KISS philosophy ;)"

"Parece como si una bobina del motor estuviese cortada, si puedes prueba a cambiar el ESC por otro, así descartas cualquier fallo del ESC."

"Este vídeo me sirvió de ayuda. Colgué mi Y6 de dos hilos y configuré parámetro por parámetro tal y como lo describen en el vídeo. OpenPilot TV Episode 2: PID Tuning from OpenPilot on Vimeo."

"Es de agradecer poder hablar en mi segundo idioma, se hace pesado hablar siempre en inglés."

"I don't use any connector, I've soldered the wires from the distribution board to ESC and from ESC to motor."

"Bullet connectors... people in the forum are always saying that it's a source of problems."

"Yes this is odd... I don't have this problem in my Y6."

"Look here: http://www.flytron.com/19-rc-shutters. By the way I use an Arduino Pro Mini with an IR emitter as a trigger for my Sony NEX-5."

"Dave, no I haven't tried it above APM because all non wanted magnetic sources are below. First I tried with a can sheet and it didn't work (it was only big enough to cover the APM, I suppose it was from steel)."

"Compass noise solution (dji style): Here the results: With compass attached to APM1: With compass attached to dji mount: Noise is gone! (But I still have yaw problems, it doesn't hold its position, I suppose I need more PID…"

"Today I've sent it back to the store. I didn't get any error, simply it was like the gps/compas was completely dead. I recorded this video."

"Do you have dual rate/expo's enabled? Be careful with the radio trim. I have APM1 and don't have this problem. As Gustav said this is probably a calibration problem."
