Sorry, I'm late to this thread, but it's an interesting point you bring up.

However, it's only applicable to what we might call "legacy aircraft" --
Pipers, Cessnas, Beechcraft, Navions, etc. All of the "modern" aircraft
(Cirrus, Lancair, Diamond) are going with stiff legs, and don't appear to be
paying much of a price penalty for doing so.

Anyone care to venture a guess as to how much faster an SR-22 (for example)
would go with retractable gear?


Consider the lancair aircraft.

The ES, with 210hp will supposedly do 200mph at 8000'
The ES with 310hp will do 225 mph at 8000'
Both of these are fixed-gear.

The lancair legacy, with the 310hp and retract will supposedly do 276mph at 8000'
The fixed-gear legacy, with 200hp will supposedly do 210 mph at 8000'

so, maybe the SR-22 would gain 30mph or so with a retractable...
