I totally disagree that it should be the same as magical flight as I said earlier.
If you want non-magical flight there are ways to achieve this without resorting to becoming a spinning top. There are mechanical devises that assist with flight that aren't magical. You can buy personal air vehicles (hang glider for 300 gp and ornithopter for 4,000 gp. See pgs. 54-55 Arms & Equipment. ). If you can deal with the alignment restriction, you can have the Feathered Wings Graft (see Fiend Folio pg. 210). You could take a race with flight or a template that grants flight.
