FSX Kawanishi H6K Mavis Update. This is an update for FSX Acceleration of the H6K Mavis by Kazunori Ito. The author has updated the flight dynamics, changed the spray effect and fixed the panel by Jim Welch (H6KMAVPN.ZIP) so it works in FSX. You need the original aircraft for this update to work (H6KMAVIS.ZIP). By Bob Chicilo.
