STEP 42 Tail Pushrod Guide Positioning
Insert three rudder pushrod guides positioned 7 3/4”, 14” and 21” from the front of the tail boom. Do not bond them at
this time until the tail boom has been test fitted with the fiberglass tail boom. Connect the long rudder pushrod to the
pushrod coupler and attach the 104mm pushrod. Note, the long pushrod uses the Grey colored 2.0mm ball link but the
104mm pushrod uses the Black 2.2mm ball link.

STEP 43 Bonding Tail Guides
To set the rudder pushrod guides, attach the tail
boom assembly to the main mechanics without
the fiberglass tail boom until the tail drive
coupler is seated into the female coupler on the
main mechanics or the tail boom extends
1.5mm past the second tail boom clamp.
Tighten the lower screws until the tail boom will
not rotate in the clamps but do not overtighten
the clamps. Attach both ball links. Rotate the
guides until the pushrod moves very smooth at
the distances listed, then bond the guides in
place with a few drops of CA adhesive. Let
completely dry.

Completed Mechanics
At this point, the various sub assemblies should be complete and flight ready to be fitted with the fiberglass components.
We do recommend that the engine be broken in at this time and get the basic mechanics trimmed for hovering. While
this can be done after the fiberglass components are installed, access to items like the rudder pushrod and rotor head
pushrods are severly limited and making adjustments are difficult or impossible. Add the landing gear and temporarily
add weight to the nose to balance the helicopter during testing. After testing, some disassembly is necessary.
