The wing and tail incidence angles sound fine.

One thing you WILL need to do is replace the spars with spruce for RC. Thanks to having an elevator control you'll easily be able to generate too much G load to get away with balsa spars. In fact I'd make the center section spars from spruce that is about 50% thicker than shown for just this reason. For the outer panels you'll want to start them with the same 50% thicker and taper down to the regular size at the tips.

Over at RCGroups a fellow did a Cleveland Albatross in the Vintage and Old Timer section. It's very similar to the Super Condor in planform and the fact that it uses gull wing dihedral. He tried it at first without ailerons but the dihedral in a gull wing is in the wrong place what with being in next to the fuselage where it has too little leverage to roll the model. He ended up with ailerons in his which I'm sure you'll need as well.

Here's a link to that thread that discusses all the issues related to gull wings on these models....
