Hello Annmarie,
OK, so positive stabilizer incidence is the LE of the stab up? This would make sense why on our planes with 0 wing and 0 stab we need negative in the wing. Kind of hard to change the stab once it is glued in. I also have 1.5 deg up. I will change the wing to -1 degrees ASAP and let you know how it flys.
