Rotax RPMs

I'm reading the specs for the Remos G-3. Looks like a nice plane. But
one thing that gobsmacked me was the note that "Max endurance: 6hrs at
4300rpm". Does it really run at 4300rpm? Is the prop geared down from
that? I mean, I normally fly a Lance with a 300hp IO-540, and it's pretty
damn noisy at 2650 rpm. I shudder to think what a prop spinning at 4300
rpm sounds like.
