Supercar Flight Dynamics

Flight Dynamics

The standard test flight model flight dynamics are highly experimental. Instabilities are possible in various modes of flight. Version 1.x and 2.1 flight dynamics were based on those provided for the Star Wars X-Wing model created by Chris Evans (dochris@pcnet.com, http://www.pcnet.com/~dochris/). This gives the vehicle a top speed over Mach 2 and short take-off and landing capabilities.

It is possible to use alternative flight dynamics settings with the visual model provided by Supercar. Recommendations are:

Helicopter Flight Dynamics - for a slower take-off, landing and low speed flight around scenic areas. Try using the flight dynamics from the Sikorsky HH3F by Angelo Moneta (monetang@intercity.shiny.it) available through various MS Flight Simulator on-line sites (e.g., http://intercity.shiny.it/moneta/oheli.html.
Harrier Jump-jet Flight Dynamics - this might make a suitable basis for slower take-off, but with a lower top speed. Try using the AV-8B Harrier II model from Brett Sumpter (BSump39546@aol.com) available through various MS Flight Simulator on-line sites
The Standard Flight Simulator Flight Shop (FSFS) Jet Engine Flight Model.

The Microsoft Flight Simulator/BAO Flight Shop flight dynamics settings for the Supercar Test Flight Model are provided in the table below. US Units are used in this table. Space for information on any customisation you perform is provided. Reports of test flights and changes to the flight dynamics of the Test Flight Model are available at http://www.aiai.ed.ac.uk/~bat/GA/SC-MODEL/MSFS/REP/.
