RWY EXCURSION DURING HIGH SPD TAXI TEST.

Narrative

HIGH SPD TAXI TESTING AND 'CROW HOPPING' OF RECENTLY COMPLETED KITPLANE. RECEIVED FAA AIRWORTHINESS CERTIFICATE. HAD SPENT ABOUT AN HR DOING TAXI AND HIGH SPD TAXI PROC. WAS ABLE TO MAINTAIN GOOD DIRECTIONAL CTL AT SPDS OF 65 MPH. ATTEMPTED TO LIFT NOSE OFF GND TO DETERMINE ELEVATOR SENSITIVITY. FIRST TIME PLANE LIFTED QUICKLY; BALLOONED. LNDG WAS DIFFICULT TO FEEL THE DIRECTION. ROLLED OUT R. SECOND TIME NOSED UP AND DOWN WITHOUT INCIDENT WITH GOOD CTL. THIRD TIME LIFTED OFF QUICKLY; RETARDED THROTTLE AS PLANE BALLOONED UP. WHILE TRYING TO STABILIZE ATTITUDE AND MAINTAIN AIRSPD; PLANE SETTLED TO GND AND BOUNCED. UPON RESETTLE; PLANE WENT TO A L DIRECTION AND RAN OFF SIDE OF RWY; STRIKING A RWY LIGHT. R GEAR GRAZED BUT PROP HIT THE COVER; BREAKING PROP AND DAMAGING RWY LIGHT. ABLE TO RECOVER CTL AND STOP PLANE WITHOUT FURTHER INCIDENT. PROBS: VERY NARROW; CROWNED RWY WITH OPEN AREA AT OLD CROSS RWY. XWIND CONDITIONS ARE MAGNIFIED. UNFAMILIAR WITH EXACT FEEL OF ACFT. TRYING TO LIFT OFF AND SETTLE DOWN WAS MORE DIFFICULT THAN EXPECTED. ACFT CTLS ARE VERY SENSITIVE; MUCH MORE THAN ACFT I HAVE FLOWN IN PAST. NO MAJOR DAMAGE. PLANE WAS RUNNING WELL AT TIME OF OCCURRENCE. PROP NEEDS TO BE REPLACED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS FLYING A GENESIS HOMEBUILT ACFT DESIGNED BY INNOVATIVE ENGINEERING. THE RPTR BUILT THE ACFT HIMSELF. THE GENESIS IS A PUSHER ACFT WITH TRICYCLE LNDG GEAR. THERE WAS NO DAMAGE OTHER THAN THE PROP AND THERE WERE NO INJURIES. THIS INCIDENT WAS NEVER RPTED TO THE FAA OR NTSB FOR THE ABOVE REASONS. THE RPTR HAS REPLACED THE PROP AND HAS BEEN FLYING HIS NEW TOY. THE RPTR CONSULTED WITH MORE THAN 1 CFI ON HIS DECISION NOT TO RPT THIS INCIDENT TO THE NTSB OR FAA.
