What a coincidence of conversation!
Sat I took a 22 over to an EAA fly in to give rides, had a blast.
When I came in I got a parking spot near the windsock away from the ultralights (don't want to blow them over, etc.)
My first setdown actually ended up with the tail upslope.
The slope itself as about 2-3 deg (beginner guess here), and before I set down I assured myself looking back (to me) that it wasn't going to rise up and hit my tail.
I actually found myself more worried that when I went to pick up later that I may unconsiously give enough aft cyclic to plant the tail rather than lift striaght up, but they ended up being unfounded. So if given a choice I would take level, but not afraid to set it down tail upslope if conditions warrent.
I did however do a walkaround of the area given and found I had room to set down skids just within the wind circle boundry of the windsock where it was level without worry to the mains for clearance and used that spot for the rest of the day.
BTW, I had a blast that day, for me racking up 2.4 in one day feels like 8. and i introduced 4-5 people into the world of rotorcraft flight, they really liked it as much as I did.
