How much can a YS .91 pull?
 
I'm planning to get a YS .91 for my next plane. Therefore I am wondering how much thrust this engine produces and how heavy the plane can be (and still be able to pull out of hovers fast).

YS91AC
 
I had a YS91AC on a Morris Hobbies 60SuDoKhoi. I was using a modified Zinger16x6 prop. Unless it was a hot and humid day (as hot and humid they get here in Los Angeles) I could pull out of hovers with no problems. On the H7H days I would have to fly out of a hover. The YS91FZ is probably a little stronger, and with an apc16x4W it should develop somewhere in the 9-10 lbs range of thrust. I at the moment fly a 6.25 lbs plane with my YS91AC swinging an apc15x6, and it rockets out of hovers.

Natrajkl,

The YS91 has about the same power as most ordinary 120s. I have a 91 on an 8lb cap. The vertical is unlimited but it would slowly climb out of a hover. If you can keep your weight closer to the 7 lb mark, it will be like DKjens say, it will rocket out of the hover.
