FSX Vickers Valiant Update. This is an update for FSX acceleration of the Vickers Valiant by Mike Stone. The author has updated the flight dynamics, changed gauges on the original panel and given it a second panel made from a modified panel background by Phil Perrott, so you can choose which panel you like better. No virtual cockpit. You need the original aircraft for this update to work (VALIANTC.ZIP) By Bob Chicilo.
