Approaches by the numbers...
I fly fun fly, 3D, and heavy and light SPADs. The fun fly and 3D type planes are much better floaters, but the SPADs I fly have a much steeper glide slope. Its all in the management of flare timing. Even a plane with a steep glide slope, like a warbird, or a SPAD QHOR, can be landed with the engine at idle. I just bring it in much steeper, and flare it authoritatively in ground effect. If it can fly, it can glide; just not at the same glideslope. Look at the space shuttle. It has a VERY steep glide slope
