Default RE: Unexpected flight characteristics

I only seem to have problems with the ground handling on this plane. But practice, practice, practice!

I measured some of the key attributes of the plane last night as follows:

Wing incidence 0° (should be +1/2)
Down thrust 2° (2° is as per plans)
Right thrust 0° (0° is as per plans)

I also check the wings for warping. The left wing is fine the right wing is 0° at the root and +1/2° at the tip. This is however due to the strip aileron and not the wing itself (I think).

This implies that the TE is lower at the wing tip than at the root. This would tend to lift the wing tip though not drop it - have I got that right?

I will add some washers temporarily at the TE under the wing bolts to set the wing incidence closer to the half degree positive and the reset all the neutral points on the flight surfaces.

I should be able to get to fly on Sunday (Good Lady permitting ) .

Anything else I should check before flight testing (other than the tail wheel alignment)?
