From looking at the video and speaking to the pilot a few things are clearly evident!!!

A. canard incidence is negative relatively to the wing... can be seen as the plane is in front of the camera.
B. pilot has to pull hard to unstick but when realize that his climb is too steep he reduces the pressure on the stick and immediately the plane went down.(spoke to the pilot)
C. throw on the canards was to high ~30mm up and down.
