Hi, I'm new to the group and I appreciate your help. I have a Matrice 200 v1 and I need to increase the precision. I saw this piece but I don't see any information about what advantages I get if I install it, how much better would it be if I installed this on my drone? thank you

This piece is made to increase the precision lost when installing an upward gimbal.
Installing a PPK kit would be more productive.  It all depends on the payload used.
