These modifications were made under FSX Acceleration so idont know if it will fly correctly in FS9. Thats why i only modified the WB version. I made as few changes to the flight model as i could, simply moving the pilots forward ahead of ther CG and making some corrections for adverse yaw, engine thrust, weight, drag and lift. The result is NOT an exact likeness of the real plane at all, but hopefullhy, you'll enjoy it..
Data for the changes was partially taken from http://jsc-aircraft-ops.jsc.nasa.gov/wb57/index.html, as well as Pratt and Whitney and a couple other sites.
This plane WILL climb well above 60000 feet, and she'll dance like a swan at 30000 if thats what you want her to do. The amount of lift from those wings is enormous, so she needs a long straight run to slow down and land, but with a stall speed of 63 knots she stops real good.
Sadly, there isnt a lot of weight on the front wheel, so ground handling as in original versions, is done very slowly and gently, as she doesnt like to turn very well..
Please keep your speerd below 458 knots from sea level to 15000. Above 60000 ft your speed will indicate 195 knots as is specified on nasa's web site above..
many thanks to Tim for the honor of working on one of his planes.. You'll find the file in the uploads section. Just search under warchild..
