I'm starting to work on my commercial maneuvers and wondered a couple things. How far apart are your pylons when doing 8's on pylons? I think mine are 1/2 mile. Pretty easy to tell here in Iowa where there's a field line every 1/2 mile. Also, how big of a radius should be used for steep spirals? I think I've been using about a 1/4 mile radius. I know I should ask my CFI but he flies big iron and is gone most of the time. Besides, he's not really "up to speed" on small GA maneuvers.
