I've been using about half flaps on base leg and go to full flaps on short final on mine. Bit of a learning curve but at my field I have to do short field type approaches and then set her down on an asphalt runway that is 40' wide and 300' long. The R54 handles it with no problem and I usually end up using only 150' during my landing roll without tapping on the brakes. If I use brakes the distance would be about 70' since the CompactUniBrakes stop this airplane with authority. They have a good deal of holding power and it's only when I have the engine spooled up past 40% power that they are not able to overcome the thrust of my FTE T-500 turbine. Makes for nice sling-shot style take-offs.
Cheers,
