I also suspect my tail surface has positive incidence? ( front is up )

I havent tried measuring it yet but when I epoxied it down I was trying to make it parallel with the wing and didnt notice the that the clamp in the back was tight (pulling the back of the stab down?) and the clamp in the front was loose (allowing the front to rise?). this would explain why I need a little up elevator trim to fly level???

I cant spend any money on an incidence meter but I read here its ok to block the plane up and take measurements of the LE and TE to see if one is higher than the other.

I dont know what I could do about it now but I'm curious...

If the stab has positive incidence could I adjust the wing saddle to match thus getting the wing and the stab to match?

And I do agree this may be splitting hairs, I'm flying the plane and having a ball with it but I find these details very interesting and can apply this knowledge when building the next plane...

It still scares me when the plane is heading towards the ground wether in a spin or just diving. But its getting better with more stick time...
