Tail boom fin poped lose on me today and caused some major damage. My patch from another crash didn't hold. How hard was it to replace the tail boom? I have a good dent in it but it is still flyable. I had the same issue with my yellow tail servo. I replaced it also. I took the yellow servo apart after reading that one of the gears in it tend to push up and bind. They suggested to put a piece of plastic in between the pin and the case. I just junked it.
