Thirty fine years ago or so, in the then Sportsman class, we sportsmen and women spent more flights and hours practicing the 3 Hor Rolls than any other maneuver we had. Untold gallons of fuel were consumed, 16 ozs at a time. There wasn't and still isn't a magic pill that makes it all go away. Hell, what fun would it be if everyone did 3 perfect rolls every time just be punching a button.

My advice, practice!! RVP, the MA pattern columnist back then, preached so many times setting up inputs for the 3 rolls for about 3-4 sec duration. His advice still holds in today's schedules; 3 sec for 3 rolls still allows enough time for the TAs. At current speeds, they should consume about 300 feet.

EDIT: Should point out that the 60 degree x 60 degree stage results in a stage that's 400 meters wide at 150 out. That's almost 660 feet at distance, either side of center. The current speed I'm referring to is about 65 mph for the well managed electric or around 100 fps and only around 70 for my poorly managed gassie.
