DJI likes wrenches

DJI is always going on about wrenches, I don't see any bolts in the F-450, so what is the wrench for?​

​

They even made a picture of the wrench on the website.​

Might it not be a metaphor for 'wrenching' or 'working on' !?!
Just guess as I don't know the context or where they are using the word?

There is a huge wrench in my DJI F-450 frame kit, probably 12mm. I don't think you would have too many 12mm bolts on a quad copter frame?

Edit: the wrench looks like the cartoon one in the photo. Maybe it is just a key chain or something to give to the kids?

Does it fit the spinners that hold the propellers on the DJI motors?

Ah, there you go, I bet that's it. I don't have any motors so I couldn't see that. They even put the wrench in a static proof bag so it won't be damaged if you just walked across the carpet with your socks on.

If you're not going to use DJI motors I know someone who could use that wrench. 

I bought DJI motors for my Tricopter (hint, hint).    I've had four of those 450 kits and never got a wrench.  Must be something new.

It is a generic wrench, if you need it then it's all yours. Would be good for a field tool kit.

I'll take it.  I want to keep it in my field box.
