I get calls to do test flights on Hawkers after maintenance from operators not comfortable doing them. The old adage "If you've seen one Hawker, you've seen one Hawker" holds true. I've had some wing drops (not 90 deg) and a few interesting rides, but if properly re-rigged, it stalls a lot like like a king air. I've taken the plane all the way to stall, and if you are prepared, it's not that big of a deal.
