One picture says a thousand words. Already own a magnetic prop balancer and didn't want to buy a second one, so I devised this method for balancing the DJI self-tightening props that ended up working brilliantly. Glass rods (if you don't already own some) or facsimile such as polished metal rods of suitable diameter will work just as well.
God knows I've spent a fortune on quad-related stuff, so getting this task done without spending a dime was a relief! Build up the end of a glass rod with electrical tape so it is a snug fit into the prop. Place the prop "lollipop" perpendicular to two other glass rods as shown. The friction is about ZERO. Use your favorite method to correct any imbalance. Glue, tape, paint, or sand. Personally, I sand the heavy side. You can see the result for yourself.
