Eachine E160 Helicopter 3D printed arm servo

Eachine E160 Helicopter 3D printed arm servo tested in normal and 3D mode without problems.
To thread the Linkage Rod https://usa.banggood.com/Eachine-E160-RC-Helicopter-Spare-Parts-Upper-Linkage-Rod-Set-p-1697921.html?rmmds=myorder&cur_warehouse=CN you have to a litle open the rod and when you finish with a gripper close a bit.
I´ll fly many times and the arm is ok I´m going to continue to test the useful life.
