From Flight International:
During flights, the GE Aviation CT7-powered helicopter has been taken to speeds of up to 162kt (300km/h), an altitude of 1,200ft and bank angles of 35°.
Not bad after 20 fh for a self funded FBW aircraft. The speed is near Vne and while the altitude looks low it is because they are operating out of a base at 3700 ft. Since 6K DA is a standard cert alt this fits into the test plan.
CTR: The 525 comes from the BA-609 and Bell 429 design teams, both before Nick.
