- 3mm shaft applied. The thinner the shaft is, the higher the accuracy (also cost higher to build).
- Come with two pieces (a pair) per package: one is black for CW and the other is silver for CCW.
- Place on two parallel edges to do balance.
- Applicable to Phantom 1 / 2 / 3 self-tightening props.
Notes when using the tool :
- Make sure the tool is seating on two level, straight, and solid edges (such as two pens in the same type, top of a glass).
- Must be absolutely no wind. Even a breath can affect the result.
- Please do not bend the shaft or drop it to the ground as this will affect the accuracy
