I don't know how widely known it is, that the Dubro prop balancer could be adapted to balance the self-tightening props, but in case you haven't seen it here's the video describing it: https://www.youtube.com/watch?v=eVdVa0jWowI I already had a prop balancer, but was not able to adapt it to the Vision props, so I bought the Dubro. I have to say, it works great. I buy my CF props from an eBay seller, who has gotten good reviews on past sales, and was shocked to find how unbalanced they were. I will continue to buy from this seller, but will always check the props before flying with them. As a matter of fact, I think any prop used should be balanced, whether it's a DJI prop or some off-brand. This may just fix some squirrely bad flying characteristics some people experience with their Phantoms.
