A Discovery Buzzer Holder.
I wasn't really able to get anything to stick to the Shrinktubing of the HobbyKing Discovery Buzzer so I made this for some extra footing on my UAV.
The Fin has an embossed 1 on both sides that can be colored with Paint to give it some extra looks.
If requested I can also do other Numbers/Letters as I wasn't able to get a satisfying result with CustomMaker.
