Hangar 9 Ultra Stick 40...lovely plane that.
I had the red and white one with a ASP 46 on it and even that howling sounded awesome. You do fast passes just too hear that thing

. The Ultra Stick is a great plane (I'm still sad I sold mine). Like the guy at the hobby shop once told me - everyone should own a Stick

. I only had the H9 one so I can't talk about the others - but that plane can take almost any beating you throw at it. Oh and the landings was a joy! You can bring her in nice and slow without worrying about stalling.
