The 20 minute limitation clearly is battery life on the Extra which is why I asked about a generator as you suggest for ETR - if the answer to that is cooling then you would have to keep 'resting' your ETR to stop it overheating.
I wouldn't get too hung up on the "Extra" motor, that was designed for an aerobatic aeroplane. An ETR would need a motor optimised for that application and rated/de-rated to provide 100% continuous output for OGE hover if that is what is necessary. The "Extra" application is just an indication that a suitable motor could be sourced.

I doubt that Leonardo would have developed a prototype ETR and ground tested it if they didn't see any advantage, or think it had a chance of working in flight.
