KF, what size props will the 130 be using?

I have a rubber powered C-130 in the works also.  It is a No-Cal Multi intended for a "Two, Three, or Four Off The Floor" type indoor contest where the model has to be a multi motored, No-Cal type scale model (Well, generally recognizable as the airplane it is supposed to represent.), rubber powered, with a 24" or less wing span, and it has to R.O.G..  I was intending to have it finished this morning to test fly at the O.F.F.C. session but life intrudes.  Anyway, it should be finished tonight for the Black Sheep meeting.  I attached some construction pictures and I'll post a picture of it finished.
