Hello All:I am looking for any info (tutorial, etc) that explains what AC config entry controls on ground stability and prevents an AC from tipping either left or right (depending on which way an on ground turn happens) so that a wing scrape does not happen while the AC is turning at around 10 kts taxi speed.I have checked out the FS2004 Aircraft container SDK but it does not provide an answer to my question. What I'm looking for is this:Which entry is it and what is the value to be changed?TIAChris

Hi,It sounds to me like either too much fuel is way out in the wings (Fuel and Weight section, lateral values for each fuel tank), or the main gear is too narrow (lateral values of lines 2 and 3 in the Contact Points section).Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Thanks Tom.I'll take a look and experiment with other values.Chris

Tom:Here is the fuel section of the AC config file. Does this appear to be within normal limits? AC is a Gulfstream V.[fuel]LeftMain= -1.800, -9.360, -1.500, 1058.000, 0.000RightMain= -1.800, 9.360, -1.500, 1058.000, 0.000fuel_type= 2.000number_of_tank_selectors= 1electric_pump=0Thanks.Chris

Hi,These values say that the center of gravity for the fuel is 9.360 feet away from the center of the fuselage (and -9.360 feet). Not that far, but it is a ways out there. Try changing both these values to 0 and see if it changes anything. If not, you can always change them back.Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___
