I must be doing something wrong. I ordered a new transmitter with the pitch control knob on the left side. I updated zen-imu. Everything else was already up to date. I checked the box for "upgraded transmitter" in the Vision 2 app. Also went through binding process. Transmitter seems to work fine, except for controlling the pitch of the camera. Also, before I switched over, when I would start the vision the camera would drop to about a 45 degree angle. Now it starts out at about horizontal. I have no pitch control with either the upgraded transmitter or the android app. Again everything else is fine and and the camera does stay level. Did I miss a step? Is there a way to calibrate the pitch knob on the transmitter?? Thanks. If this post needs to move to another place, please move it. Thanks again.
