I know, it looks like a lot of things to do... no point in
delaying, let's get started. Start by placing the two bearings (8)
into the flybar see saw hub (21). Note that if you have a 29BB
kit then these will be bushings. Slide both hexagon shaped flybar
arm bushings (20) into each flybar control arm (19). Make sure
you get the bolt holes aligned. Wait just a moment before you put
in the set screws (4). Insert the flybar (18) through the
bearings in the hub (8). Slide one of the flybar control arms (19)
on the flybar and align the bolt hole with the flat spot on the
flybar and lightly tighten the set screw (4). There are two of
these flat spots on the flybar. Push the flybar control arm up
against the hub and install the second flybar control arm on the
other side (orient as shown in the picture). Make sure the set
screw contacts the flat spot and that you can't move the flybar
in/out of the hub. Now measure the length of the flybar from the
control arm to the tip. Do the same for the other side. If it is
not equal length then loosen the set screws and slide the flybar
to center it. Once you get it centered, take out one set screw at
a time so you don't loose your position and put blue loctite on
them. Next install the ball (31) and screw (3) onto both flybar
control arms (19). While you're at it go ahead and install the
other four sets of (31) and (3) onto the mixing levers (22). Now
insert the bearings (9), two per lever, into the mixing levers (22).
Slide the sleeves (13) onto bolts (1) then install through the
bearings in the mixing lever. Put the washer (16) on the bolt.
Put some blue loctite on the threads then bolt the assembly to
the end hole on the side of the hub (21). Do the same for the
other mixing lever.
The last step on this page is to install the flybar paddles (17).
If you find that the paddles require a lot of force to thread
them on then do not hold the flybar control rods as you thread
the paddles on use some pliers to hold the flybar. Thread them on
the flybar until you see the end of the flybar in the cutout
window of the paddle. Make sure the short side of the paddles are
in front (as viewed by a clockwise rotation from above). Thread
on the other paddle and measure the distance from paddle to hub
for both sides. Make sure they are equal distances. Now you need
to make sure both paddles (17) are parallel with the flybar
control arms (19) then install the set screws (5). You can double
check by sighting down the flybar to see if the paddles align to
each other. The symptom of misaligned paddles will be that you
can get one side of the rotor tracked but not the other.
First adjust the flybar paddle closest to you so that it is
parallel with the flybar control arm. In the first picture you
can see the angle I look at. This position allows you to see the
tips of both flybar paddles. Move yourself (not the helicopter)
up or down until your line of sight is such that the tip of the
paddle closest to you is in the center of the flybar. Then look
over at the tip of the other paddle, it should also be in the
center of the flybar. If not adjust it so that it is. Don't
forget to tighten the set screws in the paddles to keep them from
turning in flight.
