On the early models I thought the stabs were adjustable, but latter versions omitted that option. This is from memory of a few years ago.
Normally the stabs would set at zero with the wings at .5 degrees. Keep in mind once you trim the elevator halves you will adjust the stabs to keep the everything even.
I would set the stabs by eye and use a digital meter to set the wings and T Can.
Also, make certain you replace the wood dowel in the CF tube. The supplied dowel is usually too short and is crappy wood.
