4*60 Wing built upside down
Ghostbear,
bummer,
Listen if you used CA and epoxy to join the wing and you have not yet used the fiberglass tape you may be able to take the wing apart with Ca debonder and a heat gun.
Use the debonder to soften the CA and the heat gun to soften the epoxy holding the dihedral spar.
Its worth a try and fairly inexpensive
