I have a few OS 46 engines (2FX and 2SF) and on the planes I wan't to slow down I use the 12x4 APC, One plane I have glides better than a Kadet (Known to glide forever) It is a Ultrasport 40+ with a YS 63FZ on the nose and this thing just does not want to come down, How I get this one to land is get a long approach to bleed off the speed a little and actually have to fly it right onto the ground and as soon as the main wheels touch it starts slowing because of the drag and a little up and it puts the tailwheel down. First flight with it really surprised me but I did dead stick it that first flight about 50 feet up and circled 3/4 the way around the field, That's when I knew landing this one was going to be a little work, Been doing good so far, I would try the 12x4 on your plane and do what Borzak suggests and you should have better luck with your landings.
