Before you start chopping the wing or stab, just remember the incidences you measured (0 wing -1 stab) are in real life saying that the stab is set at 1 deg less possitive incidence than the wing. For example, lets say in real life you wing is set at 3 deg poss, and the stab 2 deg poss.

I put your side pic against the profile (hardy rocket science but it gives a quick impression)... and they're quite similar.
Whats obvious is the engine thrust angle as mentioned earlier. I'd start there... it's the simplest.

How do you measure it? Best to fly it in. Meaning add some, add some more untill you find the best place.
You'll have to built a spacer to move the engine out some, then add a spacer at the top of the mount to angle the engine down.
Start with 5mm and add/adjust as necessary.
Be informed that you'll very likely need to add some elevator mix to high throttle as the design was never ment to fly at the speeds we fly are models.
Good luck.... and remember, what ever you do, have fun.
