the wheels the wheels....ah yes....
there are some fairly complicated (relative term) interactions
going on at the back of the wheels where the air is trying to come
out of wheel...around wheel...and its interaction with components
in close proximity..ie fairing........of which we would need rolling
surface...and spinning wheels...........
Pork Pie.....where are ya........he has the hands on knowledge base
with this (in some cases) critical area of aero....
