Aircraft; Human Factors; Procedure
While practicing ground control and taxing on RWY XX at 30 MPH; maintaining centerline with nose wheel raised. The aircraft began to lift off; I reduced power and added up elevator then applied additional power to slow settling. I over controlled both power and elevator resulting in pilot induced oscillation (porpoising). The aircraft impacted the nose wheel twice with the second impact resulting in collapse of the nose gear. The propeller struck the runway then the right-wing tip drug followed by the left-wing tip. I called tower to request assistance and let them know that I the single occupant had sustained no injuries. I turned off all fuel; power and ignition then unbuckled and exited the aircraft. I picked up the pieces of the damaged propeller and by pushing the tail down was able to push the aircraft off the active runway on its mains. I then waited for assistance to arrive. The weather at the time was wind calm; sky clear with reported visibility reported better than 10 miles.
CH701 pilot reported a nose gear collapse and propeller strike during taxi practice caused by improper procedures.
