I put prop tape on my Catto 3 blade prop today. In all fairness, I did a less than perfect but OK job of applying it. Struggled a bit with bubbles and getting them deflated and smoothed. Afterward I went flying and found a decrease in performance of just less than 4% at 2700 rpm. This amounts to the equivalent of a decrease of 11 horsepower if I did the math right. I took the tape off.
