I have a 32 bit board mounted to a multi rotor with 2 axis gimbal. When I use the 2.60b4 firmware it will not level on boot up. It will hold its position, I can move the camera to level with my hand and it will hold the position it is left in. I have tried setting the button to level pitch and roll but it does not bring the cam level. If i switch back to 2.56b7 it levels on startup automatically. I have recalibrated the IMU's and tried an EEPROM erase and still no joy. Any other ideas?
