Yes, of course.
There are two scalars you can use.
One is in the Flaps section, there are two in the Flight Tuning Section.
lift_scalar = 0.3
drag_scalar = 1.0
pitch_scalar= 2
system_type = 1 // Hydraulic
An increase of .1 equals a 10% increase in value.
[flight_tuning]
cruise_lift_scalar=1.0
parasite_drag_scalar=1.0
induced_drag_scalar=1.0

To go a little further on what Milton posted...
Parasite Drag is overall aero drag - think exposed rivets vs. flush rivets.
Induced Drag is only invoked as the angle of attack increases. Something like a pencil-winged glider would have a low induced drag, while something like a delta wing would have a higher induced drag when is shows that huge under-wing area to the oncoming wind.

I would add that if the lines for lift/drag/pitch scalars are not in the flap section you can type them in with some common values. The same thing applies to the flight dynamics section. I have only had one CFS model kind of reject some edits like these.
I also thought that extending landing gear added drag via the induced drag scalar as well.

Not according to the Container SDK, but rec 1101 in the air file contains a drag coefficient for the landing gear. If I remember right, the last time I tried to play with that, higer drag also induced a heavy nose-down pitch.
I will also add that if cd_df drag is at zero in the air file, the induced scalars will not help in flight tuning and Flaps sections.
Do not be afraid to open the air file (just back it up before changing).
Check the Drag section in table 1101; increase values by 10-20% until you get the feel you want.
Be advised that if you have table 1540 for drag derivatives that these values may override the values in table 1101. These 1540 values are stated differently but if you divide the table 1101 drag values by 2048, you may find the equivalent 1540 values I believe. You can test this before you do changes and maintain whatever relationship you have now.

I don't recall adding gear drag doing this but I usually change tbl 1101 cmg-Pitch moment - gear at the same time to give me a little pitch down moment on gear deployment in addition to adding gear drag with cdg - drag gear.
I can't remember for sure, but I think the plane I was working with at the time was the CFS2/FS8 Pro Corsair that I'd imported into FS9. I was trying to increase the gear drag to better simulate the effect that the flat panels on the front of the mains might have. The odd pitch side effect could have been a side effect of the fact that it was still a CFS2 plane at heart.
