If you are looking at this stick to buy it: RUN!!!!!!!!!!!!
If the wing is off center by 3/4", imagine what other surprises are waiting for you? Have someone hold the plane up with the nose pointing at their chest and in a basically level attitude (like it was flying straight). Now, you stand back about 10' from it and eyeball the tail to wing alignment. Does the stab look like it's parallel to the wing? Does the rudder/fin look like it's square to the stab? It's probably crooked as a dog's leg.
Nobody sells a good flying plane.
