I'm building a Techone Mini-Eagle biplane. It has dihedral on the bottom wing. I have heard that by installing longer wing struts to make both main wings
level & paraellel to each other that plane will be more aerobatic. But I'm not sure that this plane with a 17" wingspan handles well without dihedral.

Anyone built this plane without dihedral to the bottom main wing? Recommendations?

Thanks much!
