Beautiful model and great flyer. Pretty ballsy to stunt the bird, though. The airfoil was not designed for inverted flight. Only the fact that he has the power-to-weight ratio let him get away with it.
Here's another beautiful giant scale model, and yes, this is a scale B 52 with real axial-flow turbine power. Notice the spoiler flaps and the landing lights when he lands.
