Is it possible (PBF)?
The natural tendency for a PBF when in the fullest upright torque roll position is to flop over on its back. But I have been able to get about 2 complete revolutions before falling out. And since the wingspan is very narrow the torque roll rate becomes very rapid once it is set in motion therefore making it difficult to keep up with. But to answer your question....yes it can be torque rolled but its not that easy.
