John is correct, but you should realize that the 'tail length' (distance 
between the aerodynamic centers of the wing and horizontal tail) will be 
shorter.  Part of the success of current aerobatic designs is the 
increased tail length compared to airplanes of an earlier era.   The 
good news is that the amount of wing movement you will probably need to 
properly balance the airplane is fairly small percentagewise and should 
not degrade the airplane's performance very much.
