Also, daoldguy, if it pitches towards the gear on KE, you might want to try moving the bottom wing down about an inch using an extention
Power off, I can let go of the controls and it will just float to the ground, inverted, it needs a touch of down stick to stay level, indicating a little nose heavy to CG.
Your thought is the coupling is related to the bottom wing needing seperated from the fuse, moved down about an inch, extending the wing struts and having a cabane added below the fuse?
