Doing STOL , the best way to approach this that I have found as a safe format,..do it at an airport on grass or a big field,but first ,..since every plane is a little different,..get some altitude and do a few power off stalls,..take note to see if the stall breaks at the same indicated speed,..now..do a normal approach,..have something on the ground as your target,..ie a couple of orange cones or a flower /powder line,..a strip of orange marker tape with a rock on each end,..any visible marker..land normally and check your roll out distance without brakes if possible, sometimes you have to use brakes to keep the tail behind you,,..a second person on the ground is always a great help to check your target accuracy or mark the end of your roll out,,..once your comfortable with a normal controlled crash er I mean landing now add a little more flaperon,..and slow your approach just a couple miles an hour slower,..just pay attention to your speed during descend,..and stay above the previous stall indicated speed,.
if your aircraft has the stock gear,..it's a little more difficult at first to avoid a bounce,..if you have larger tires ..deflate them a couple lbs to add a little forgiveness ,..if you can get the tail on the ground at the same time as the mains ,..chances are you are slow enough that you shouldn't bounce too much depending on the surface of the landing area,..
when you get it right,..you will "Feel" the plane ..as it becomes more of a part of you ,..like wearing your favorite pair of jeans ,,like a family re union ,..between you and the plane,..if you have ever operated a bull dozer and can tote a blade pretty good,..it's the same thing..you "Feel" the blade ,.through the seat of your pants,..if the blade drops grade you don't even think about it,..your muscle control automatically fixes it,..
back to planes..once you've done this practice on a grass strip or large field,.. while your practicing check your winds..try with a slight quarting wind left,,right..if the field is big enough to do so..
on the days you can't fly,..but are or can be at the site that your practicing for,..check the winds there,..top of the tree's .to the ground .allot of trees? surrounded by water? dark areas? all things that will cause sink..light colored areas? parking lots? all areas that will cause lift,..does the ground drop away on either end of this area that your practicing for? this can cause sink too..all of these factors must be addressed, and I'm not trying to scare anyone out of doing STOL,..just bringing to your attention all the factors that can effect STOL operations
