yeah. i dont like cutting the center ribs. maybe no big deal after gluing all back togther but definitely dont sant to cut those spars in the center, then id have to add a brace.
heres a close up of the wing joint i will cut to add dihedral. im gonna lose all that strength because its a single 1 inch by 3/8 inch spar. pic 2 shows how i split that into two in antoher plane - two 1/2 inch by 3/8 inche extended spars which i slid together and wrapped up with thread and ca.
i might have to just save those 1x3/8 spars and replace with two 1/2x3/8 which I can slide together only this time leae teh second out until after i cut and make the dihedral. same effect - add long 1x3/8 spanning both wings to skip a dihedral brace and cutting the ribs.
