These ball ends are the best. If you want a slop free linkage system then look no further than these ball ends. We use these ball ends exclusively on our F3A models for this very reason.
- Pre-threaded for 2.5mm push rod.
- Have a Ceramic ball for ultra smooth motion.
- 2mm through bolt to servo arm.
These particular ball ended were used on our Allure in conjunction with Ralph Schweizer 2.5mm titanium linkages on the the ailerons and elevators.
