How difficult is it to change an aircrafts flight characteristics ?  Years ago I was the proud owner of one of these aircrafts, I could land this aircraft from 1000 feet over the end of the runway by reducing the speed to just above the stall speed as I applied the flaps (full). Point her to the ground and never have the speed increase beyond 72 -75 Knots, try this in FS9 and you have no hope of stopping the beast accelerate beyond these speeds. I would just love it to achieve this type of performance. Any help appreciated.

Open the aircraft.cfg with Notepad.
Find the Flaps section.
Change the ...

lift_scalar = 1.0                                       
drag_scalar = 1.0

... as necessary to achieve the desired result.  Each .1 equals a 10% change, therefore 1.1 equals a 10% increase in lift/drag.

Check to ensure your aircraft weight is not full, cargo and fuel.

Secondly, are you sure that the throttle when pulled back is at zero percent.  In the VC, point your mouse and look at the tooltip (if turned on) to check throttle percentage.

It could be that even at low throttle in FS, you are getting more than RW thrust.
