It’s a Flettner Type Trim, so it has no effect on Control Effectiveness and with a fully forward Control Column the Nose should drop.
However, the Columm has no effect whatsoever and the Plane doesn’t fly, it lifts off with the tailwheel firmly on the Ground, points the nose 90° up and then reverses into ground.
No amount of trim can correct or create such behaviour.
On the Take-Off Roll it is impossible to lift up the Nose by pushing forward.
