Re the model aircraft 'blender'; if it's no longer decending, it's no longer spinning (if it ever was!).

What I saw in that vid was a series of down vertical aileron rolls, followed by an inverted spiral dive (aeroplane inverted and rotating, with down elevator applied).

The clue that it wasn't spinning was that the aeroplane recovers by the elevators making the tail go down even more and presenting the inverted wings at a greater AoA to pitch the nose up (if it had been spinning inverted it'd have just mushed into the ground as more down elevator is applied - just like more up elevator would cause in an errect spin).

Once nose-up, excess engine power pulls it into a climb.
