 The empty weight of the prototype was significantly beyond predictions and the unsubstantiated rumors within the industry are that the aircraft's performance during the test flight was below what was expected, and it does not appear that much flight test activity followed the initial flight.The prototype aircraft remains stored in a Scaled Composites hangar.A follow-on design, TAA-2, (substantially similar airframe with retractable landing gear, upgraded avionics and higher performance engine with constant speed propeller) was also envisioned however never made it to the prototype stage.
