I don't know if they'll be too big? I was looking mostly at the recommended prop sizes.. the biggest prop I can have is a 10 inch one..
Finally, I have a couple more progress pics! I finished up the painting on the hull. I still have to finish the fuselage part. I painted the whole thing with the grey prop enamel, then I taped the bottom off and painted the top with white enamel. I'm definitely going to have to come up with some decals I think.
