Default CRJ700

In the great wisdom of MS they put out the default CRJ 700 with a downward pitch. I am not good enough to fix this problem, is anyone out there aware of how to fix that downward pitch on the CRJ 700? I for one would be happy to acknowledge the person who does this.
I am becoming more and more adept at reprogramming the add-ons and default planes and helicopters, but as of yet cannot fix this type of problem.
Please let us all know if there is a fix for the downward pitch in flight of the CRJ 700 or any other of the default planes that Microsoft put out.
