The Airfix 1/48 Canberra kit all suffer from a fairly significant error at the horizontal tail and vertical stabilator and rudder. The issue stems from the horizontal tails not being joined to the fuselage like the real item is. This creates an issue with not just accuracy but also the dihedral of the tail section. Our set corrects this.
The vertical stab and rudder also suffer from a fin filet which is too far forward and a rudder which has ribs scribed in. This is simply not present on the real aircraft. Our easy to assemble and use correction set also takes care of this issue giving you a much more accurate Canberra.
