The airplane will fly at a lower angle of attack, which should result in a 
decrease in drag (all other things unchanged, you're getting lift for free).  
There's no way to tell what's happening in your case without seeing both the 
previous and present versions of your config files.

Your original problem was takeoff speed.  Sometimes the problem is not lift 
but rather elevator authority (or CG location).  Did the airplane rotate at a 
reasonable speed?
