Thanks apolloheli, I'm very familiar with the set up in the 365 with the Arriel engine but that angled projection at the front of the Hill engine looks like a very strange way to mount a direct drive starter.
If they have gone down the Arriel style route then they have only reduced complexity a little since you need a reduction gearbox at the back of the engine, something they didn't refer to or glossed over.
That is the first impression I got also .... sounded like they were saying they had eliminated the gearbox ... wow ..... I went back and listened again and it is just the accessory gears for starter - pumps etc.
It is around the 10 minute mark of the video.
