Not viable
Having had a blade strike in a R44 with no other damage to airframe to worry about I paid nearly $200,000 Aud to have it rebuilt baldes, mrgb,hub,flex plates, etc sudden stop on engine that always doubles in price because they won't put it back in with anything remotely worn. Most of this cost was because frank says so if it had been a 500 or jetranger it would have been blades only. The market especially for 44's absoloutley hates accident history machines. Unless you intend to keep and use all these hours, you will never get your money back. If you send it back to the factory then it might work but that cost will be as much as buying a good one. Don't Don't Don't
