I have OEM prop guards. Purchased a new case. Phamtom 3 won't fit with the gurads on. Can someone suggest a quick release system for my DJI quards?
Thanks

Do a google search for Summitlink Snap On/off Prop Guards and you'll find a bunch of different places to buy.

Be careful of the cheap snap on prop guards, I put a set on my p3 and on the third flight one of the middle struts broke at the root and came into the prop causing a crash. Luckily for me there was a very small amount of damage.  

AerialFreaks ....... I like the fact they do not require removing motor screws, they are molded not 3d printed and fit very snug. I bought a set but have used only once and removed as I do not fly in doors or over people.

I had first bought a set of the Summitlink but they were a pain to quick release because the tabs were so small it was difficult to squeeze them together.

I would suspect they all come with pros and cons

Firebolt has serious spec, fit and finish issues. (3d printed)

afterdarkled.com are OK, (also 3d printed) but not as snug as the molded AerialFreaks.

Do your homework and get as much feedback as you can.

No problem with Summitlink for me.  I wish I had had them on for my one and only accident.  It may not have happened.
