The plane is built straight and well (minus the wing dowel holes). It doesn't require full rudder/aileron to fly straight it requires the trim tabs on the transmitter to be full right. When the trims are centered the control surfaces appear to be straight. The plane easily turns both left and right properly once the trims are put in. Now my setup isn't using maximum throw on the surfaces so the trims are making small changes. I was more concerned with the balancing and the excessive elevator. I think I can trim the rest.
