 He then flew the aircraft back to Reggio Emilia where three more dives were made on 27, 29 and 31 August.According to De Prato's account, the tests concluded that the "shaking" began at true air speed and that they were caused by inadequate dynamic balancing of the empennage, the balance likely lost during full excursion rudder maneuvers performed during dives.After correcting the balancing, de Prato dived the aircraft to TAS convincing himself that the structure of the Re.2005 was fully capable of high g maneuvers.
