I also built the 600 series cub, and yes; there can be interference there. I ended up rebuilding the whole Cub from contest wood because it was super heavy, and did not fly well. I made an alteration on the 2nd Cub. Before I cover the fuselage I am going to install the rubber, and check if the Cessna 601 has the same problem. I purposely set that 1/16" sq. cross brace higher than on the plan. I also am going to see how the balance is, and if I am tail heavy, I may infill the front. I ordered some 1/8" FAI rubber, and some peck poly props. All I have is 1/16" FAI rubber. And 5" Guillows props. I think a ^" prop, and the 1/8" rubber will work better on the 600 planes. I got the thinner rubber for My Bird Dog which is slightly smaller, and lighter. I hope this Cessna flies as well as the Bird Dog. Man I wish they still had CO2 motors around. I have not weighed anything yet, but I got a feeling its going to be tail heavy. The surfaces are huge, and the fuselage is long behind the TE.I added a B-0 behind the cowl of 3/32" balsa for thrust adjustment and strength. Took a page out of Mitchs' book there. I did not even dope the framework to save weight. And I sanded. A lot. And I made a copy of the plan before I started. A good habit I've found out. I used it to make templates, and the original plan is still like brand new. I plan on building it again as a micro light RC plane at some time in the future.
