Just something on the tail boom to protect it from flybar strikes. Usually doesn't happen but in hard crashes it can hit and dent the tail. After a few times it would weaken and bend.
I used a foam collar from the landing gear of a larger heli, they were meant to pad the landing on hard ground. Others have used the foam rings that some TXs have on the sticks when first packaged.
