Disconect the linkages and remove head.
Remove the washout linkage (8) from the swashplate and lift off the mainshaft.
(See Step 5) Look at the washout linkage (8) and use a xacto knife relieve
part of the arm so it can fold back the same amount on both sides. They
need to be beveled inside the 'Y' on one side.
Flip the washout assembly upside down, slide it back on the mainshaft.
Reconnect it to the swashplate and move it around to make sure enough material
was removed from the Y arms.
(See Step 11) Take the head and remove one of the M4 nuts (7) from the
feathering shaft (24). Pull both bladegrips (23) out and rotate them so
that the linkage arm points forward. Reinstall the nut (7) and tighten.
Modify the doublelinks (26) by removing one of the short ball links and
installing a regular length link. Use CA to secure the link.
Take the Main Rotor Hub (Step 11 #30) and unclip the linkage from the
Mixing Levers (22) and the two Oval Links (25). Remove bolts (2) from the
Seesaw Hub (21), lift the entire flybar assembly off the Main Rotor Hub
(30).
Take the whole flybar assembly (flybar, hub and mixing levers) and rotate
180 deg (flip it over) so that the arms (19) face in the direction of rotation.
The short arms of the mixing levers (22) also face in the direction of rotation.
Reinstall the two bolts (2) into the hub (21) with loctite.
Turn both flybar paddles (17) 180 deg so they face the right way again.
The main blade bolts now go in from the bottom because the recess for
the hex nut is now on top.
Reinstall the head on the mainshaft and connect it to the swashplate and
washout linkage. Replace the TT M3 Jesus bolt (Step 12 part (1)) with a
hardened, shouldered bolt.
Completely re-setup the pitch and cyclic systems.
Once you are all done it should look like this:
NOTE!!!! If you look closely, the Paddles are installed the wrong way.
In step 9 the paddles must be rotated 180 deg.
