Joe,
You right! But there were more than a few that hit the LHS shelves that had "left" thrust built into them! Mine was like this, perhaps a 1/16th of an inch of so, either way you will need to addresas the issue if you want to 3D with this airplane.

The tail on mine is dead strait when checked with a Robart incidence meter so I think the chinese had a role to play in that situation as well.

Like I said a few posts back, I used an OS .91 four stroke in mine all last summer and didn't get the Saito 1.00 in it till late September so I know how it flys with that engine. The .91 is plently of engine for the plane, until it gets over 100 degrees here in NE, then it simply won't pull out of a hover. The 1.00 on the other hand is PERFECT for this airplane and I like it much better than the .91. The extra thrust the 1.00 provides really helps to "shove" the UCD around during hovering and waterfalls tightened right up with the extra air flowing over the tail, helped everything out really.
