I have a DYS eagle eye, second hand. It's newly balanced.

Imus are calibrated, fresh battery, wiped the firmware to the latest stable.

The Yaw output however is crazy. It just oscillates perfectly a few degrees. The monitor window shows a perfect sin wave on the axis.

When i try autorune for yaw the software just alerts to missing steps and turns yaw output off? Oddly enough however the Yaw keeps going...

Even when i manually disable yaw output the motor keeps doing this? It will only stop of i disconnect the Yaw lead from the board.

Anyone else run into this? Testing with a multimeter? Just get a new yaw (one with encoder would be good).
