I'd be more worried regarding the fin alignment than the tailplane. Although, as BMathews has said, the tailplane will look out of line, it wont have as much detrimental effect as the fin will. You could trim the fin with rudder correction, but this will only be a constant at one particular airspeed. In other words, the plane will be crabbing or yawing constantly whilst flying. If I were you, and I'd not got too far into the build, I'd be taking this plane back to where I'd got it from. However......... normally the conditions of guarantee state that you are responsible 'after' you begin the build.
