A guy at our field today was flying his ROO powere d by a JetCat P80. He was doing lots of vertical passes and at one time almost came to a stop vertically then pushed hard over to get the nose to come down. The nose did infact come down but continued down and actually back around...a tumble type of thang...He could not get the ROO to stop doing this...he added full power in hopes of flying out of it but the nose just hung there while the ROO continued to spin and flop...finally I am sad to say ... it ended in a turbine shut down prior to entering the forest and impacting a larged tree. The plane is perched 75ft up and will be rescued tommorrow morning. So tell me what needs to be done to recover from this aggrivated stall condition. Power to idle did nothing either but watch the nose rise.


Thanks
