MIT did a study on this and the summary was posted on one of the GB
owners forums a couple of years ago in a discussion of this topic. The
MIT study showed that a locked prop always produced more turbulence (aka
drag) than a freewheeling prop, and that the overall drag penalty from a
freewheeling prop was always less to some degree than the locked prop.
Obviously the more "freewheeling" the prop is, the less turbulence it
will produce.
Marin - Can you provide a link or a copy of the paper? This is good info!
