From parts bag 6, assemble the landing gear by attaching the Aluminum Skids through the Struts, securing
them with four 3x5mm Set Screws. Set the distance from the rear of the skid to the strut at 35mm. Attach the
landing gear to the main mechanics using four 3x16mm(30) or 3x20mm(50) Machine Screws inserted from
the bottom of the struts and through the M3x9 plastic spacers into the lower side frames and secure with four
M3 locknuts.

After flying the model, if a vibration is noticed on the horizontal fin, you can remove the
complete tail rotor assembly with the hub and further balance it using a High Point balancer.
Careful sanding of the rotor blades is all that is needed.
Leading Edge
Snap the ball on the tail rotor
grip into the adjoining pitch
slider link on both sides.
Install the Tail Rotor Blades
shimmed with 3x10mm plastic
washers on both sides using
two 3x20mm Socket Cap
Screws and M3 locknuts.
Note the direction of the
blades on the diagram, the
straight leading edge of the
blade should be on the same
side as the ball on the blade
grip. To tension the blade
bolt, start loose and tighten
until the blade holds horizon-
tal but pivots freely when
shaken.
