Design Notice: the latest ALIGN TREX Series "V2" Metal Tail
Rotor Holder Assemblies (H50119A/B and HN6013A/B,
characterized by clear-anodize) have a thicker rotor grip that
can interfere with the outer-race of the flanged radial-ball
bearing. The document (,pdf) to the right provides instructions
for the required modifications to maintain the performance and
aesthetic advantages of the KDE Direct design.
