DJI Naza F450 Quadcopter Broken Arm Could Have Been Avoided with Preflight Check

Just wanted to share my experience after going from Turnigy 1300kV motors with prop savers to iPower 950kV motors with prop adapters. For starters, I do not recommend using prop savers other than for basic backyard flying with no payloads. I can't count the number of times one of my prop saver o-rings busted in mid air.
Yet being new to prop adapters didn't spare me from any crashes. Just yesterday I was anxious to get my Naza quad in the air and I didn't do a preflight check. If I would have tightened my prop adapters then I could have avoid time, money, and frustration! This video talks you through my experience and from now on I'll be checking my adapters before and after every flight!
Luckily the damage was minimal and my DJI replacement arms should be here this week. So all in all I fared pretty well given the circumstances. The quad did a hard dive from 30 ft in the air so to lose just one arm was pretty impressive. These DJI flamewheel frames are insanely durable despite the many YouTube videos that say otherwise.
