One of my prop nuts vibrated off causing the Phantom to tumble down and snapped the plate on the GoPro mount. I found some No 6 lock nuts but they don't seem to be getting snug enough to engage the locking gasket. Are there any alternative replacement nuts out there that may be more reliable? Or I'll even take the original ones, and just try to remember to tighten them on a regular basis. But since I got my Phantom off of Amazon I really don't have a contact for a dealer to order a new GoPro mount or replacement nuts. Any help is greatly appreciated.
