Thank you Todd,
It’s possible to unlock the head to tilt the vertical harms and so, the camera. With a quite strong tripod with counterweights it’s OK, but as the main axis of the crane is above the tilt axis of the tripod head, this might quickly result in a heavy weight on the front or rear. I think mounting a small head on the crane could be a nice improvement, it’s definitely robust enough.
Thanks again for your feedback.
