While pulling up on the mainshaft, push down on the lower split collar seating it
against the bearing and tighten the 2.5mm screw. Push up on the upper split
collar, seating it against the bearing and tighten the screw.
These are “special” bolts in that we turn the heads down to fit the collar. They
do not require loctite, but they DO require a hardened Allen driver to tighten
them down and loosen them without stripping the heads out. Cheap sets of
tools at this point are NOT your friends.
Tighten the upper main shaft bearing block bolts, and tighten the forward bolt in
the bottom bearing block.
The constant driven tail system is available as an option AND consists of 2
aluminum hubs, 2 machined delrin gears, the autorotation hub and a longer main
shaft.
