I worry about it, but I've never had a problem with lack of torque.

I've noticed the term "hover" means at least 3 different things.

1. (And the most widely-used definition). Where the airplane is at or near vetical nd "hanging" on the prop.

2. Where the airplane is pointed into the wind at a more-or-less level attitude and ground speed is near 0.

3. A variation of 2 with the airplane at around a 45° up angle. (Which is actually a harrier going upwind).

Sigh..
