I have a Kadet Sr. and a Mark II. Used Goldenrods on both supported at each former. Never a problem with binding or anything else. Replaced the originals after the model was built and covered on the Sr. Just drilled the supports, slid them down the outer rod and used a piece of wire to hold them in place for the glue to set. The Sr. is in a pile after I tired to land it floating backwards in a 10mph headwind (worked so mnay times before.) The MkII is still one of my favorites for relaxing flying.
