Step 4 Bell Mixer
Press one M3x7 flanged ball bearing into
one side followed by one M3x5 spacer and
another flanged bearing from the opposite
side. If the bearing is tight, lightly sand the
bell mixer and use L262 Red threadlock
to bond the bearing in place. Install the
CNLR1014 short steel ball into the single
hole side of the bell mixer and install the
CNLR1020 medium steel ball using L242
Blue threadlock. Install the medium steel
ball according to the table to suit your fly-
ing preference. Use the center hole for sport
flying. Make two assemblies.

Step 6 Main Blade Grip Assembly
Using an available M3 screw, care-
fully form the threads in the blade
grip arm. Slide the M3x18 special
socket shoulder screw through the
bell mixer arm from the flat side, add
one M3x5x3 spacer and apply a drop
of Slow Cyanoacrylate glue or Epoxy
glue to the end of the threads before
installing into the blade grip. Tighten
the bolt until there is no end to end
movement, but do not overtighten
the bolt as you can strip out the hole.
Make two assemblies.
