Includes 4 spare arms for the updated TP3
EASY TO REPLACE
These are indeed spare arms. Glad they are good and cheap
you will eventually need those
Yeah so, I like to keep spare parts on hand, so I ordered these. The arms are surprisingly resilient to snapping, but start to "go all jello" after a few violent crashes. These are cheap and easy to replace, but order a bunch at once so shipping doesn't get ya.
