Review on MAS Upgrade Propellers for DJI Phantom 1-3 with Built-in Nut - Green (4 pcs) by Jacob Rasmussen

Great packaging, the blades looked cool. I put her on a standard Phantom 3 and elevated it to a 5 foot hover. The whole car was vibrating, which was enough to notice, even on the camera video. I swapped them and still the same. Re-insert known-working original DJI-branded blades and there will be no vibration. I've only bought and used DJI Blades in the past and never had this problem. They have always been balanced right out of the box. Luckily, Revain does a great job with returns/exchanges and sending out a replacement kit. Hopefully the replacement blades will even out, but if the replacement blade does the same, I have to put up with the fact that its quality isn't very good. I haven't seen any feedback on this issue so I really hope they work. I will also see if the blades can be balanced. I've never heard of it, but I'm new to flying (2 years or so) and like I said I've never had any balance issues.
