Still no plans to flight test?
If this were a full-sized aircraft, the design process would look really strange. The avionics and pilot have been separately tested, but not the actual airframe, engine, or maneuver-control. Yet the design team is having beers all around and declaring the system ready to fly.
It's a long step from a passive paper glider to a rocket-powered, self-steering craft (of original design, I might add). It would be really nice to know if it can fly straight and stable, the control surfaces not jam under load or simply tear off, the autopilot can actually fly the plane in a stable profile, minor details like that.
I've eagerly followed the SPB's mayhem for years, and wish the project well. I'm concerned by this heavy focus on monitoring when you have no idea if the aircraft actually flies.
