Broken tail booms are still cheaper than new rotor blades. Example: 1st hard ldg = cracked tail boom...super glue or electrical tape does the trick. Second hard landing...better have a new tail boom in your parts bin. As soon as I see a crack in the tail boom...I order a new one. I've replaced 3 tail booms (my fault). BUT...only replaced 1 set of plasti-blades and they are still useable. I know where the strike zone is in the tail boom. If I got off my lazy hindend, I'd put a cushion of elect tape at the strike zone reducing breakage to a degree.
