Analysis

While intentionally performing stalls, the plt was unable to recover the acft from a nose high attitude before colliding with terrain. After the accident, weight & balance calculations could not be performed to determine the c.g. as the plt would not provide the pertinent information. Velocity manufacturer personnel stated the c.g. was aft of the limit. As a result a letter was sent to builders/owners of these acft advising them to refrain from operating the acft with a c.g. aft of 118.5'. A second letter was sent which advised owners to modify the wing fuel tank bulkhead locations as well as to suggest possible changes such as: limit the acft c.g. range; shorten the canard; move the engine forward; & change the fuel tank strakes. The pilot stated that the purpose of the flight was to test the modification of the canard.
