Almost three months have past since the Defiant’s First Flight. Any flight test updates? Not unusual for a new aircraft to be down for a month following First Flight. But three months?
As with Raider, flight test is progressing glacially. As of a couple weeks ago, supposedly SB-1 had completed its 3rd flight , hovering to 150 ft and 10 kts air taxi.
Raider has actually been flying since mid last year, demoing in secret at the request of the Army while also testing numerous desperate attempts to fix its gargantuan vibration issues. SB1 may be going down the same path as it (amazingly) did not incorporate many lessons learned from S-97.
