A typical light twin typically holds altitude quite sufficiently on a
single engine.

We weren't talking about typical light twins, we were talking about ultralights.

A feathering prop is not required for adequate single engine performance
in a very light plane. The Leza AirCam is said to be able to take off
on one engine. (I'd provide a reference but their Web site is useless.)

The aircam is hardly typical. The thing has exceptional power, 200 HP in
a 1000 lb aircraft and the engines are mounted as close to the centerline as
they could get.
