Analysis

Acft was observed to takeoff and turn right crosswind. Drng the crosswind, the RPM increased suddenly. The acft pitched nose downwards, impacted the ground in a vertical descent and burned. The plt/builder had a total of 5 hrs in the new acft. No evidence of pre-impact structural, rotor, or system failure was found during the investigation. A representative of the manufacturer of the kits for the acft indicated that the acft is easy to overcontrol and can lead to porpoising which is difficult to correct.
