    Hit garage with DP-C prop cone backing up, how to tell if any damage.

    Dumb move, wasn't paying attention backing into the driveway. Hit the prop cone (not prop), drive all the way up, on the metal garage door, enough to dent the door. Wasn't going fast. Back prop seems to spin true, no visual bent shaft wobble. What is the real way to know if I've done any damage?
