This was a high speed taxi with a brief lift off and landing for my experimental amateur built aircraft. I am at the beginning of the 40 hour test flight period but had a necessary crew member due to previous failure of the EFIS on the left side. The crew member was intended to call out speeds up to 80 KTS (which was the rotation speed) from the small EFIS on the right side. I was successful in rotation and brief flight and on landing the front gear collapsed. No injuries and limited airframe damage. Gear collapse was due to failure of a nose gear component.
An SQ2000 pilot conducting a very short EFIS airspeed test flight took off then immediately landed where; upon nose gear touchdown; it collapsed.
