Hi folks, I just installed a new set of blades on my dji 1000, all went well with the flight for about 10 min. I was about to land when all of a sudden I slung a blade and crashed...The hold screw was still in place so that means the blade broke off. I dont think I over torqued the blades when installing but I'm not sure at this point...any ideas?

I would contact Dji.  Could have been a bad blade which is rare but very possible if you haven't over torqued them.  I am going to warn you that they will most likely not do anything.  

Please contact your local dealer or DJI technical support for fully detection and repair.

Thanks for the reply!
