First we need to assemble the tail rotor shaft.
Press the gear together as shown. Sometimes this can be done by hand.
I use a block of wood with a hole drilled in to to press the shaft into the gear.
Line the gear up with the hole and insert the shaft as shown. Using a vise, or C clamp press the shaft into the gear as shown.
These are the parts we will be using for the time being.
You want to make sure you use thread lock on the whole tail box. You don't want that falling apart in flight.
Attach the right bearing block as shown.
Install the shaft and belt as shown.
Next install this cross member screw and install the first aluminum bushing.
Next make sure the bearing is pressed tightly into the wheel and install the wheel.
Install the second aluminum bushing.
Now we will close up the tail box with this bearing block by screwing the cross member with the tensioner wheel into it.
You will want to make sure the cylinder shaped cross member is installed in between in the far back as well.
Install screws as shown.
Secure rear cross member as shown.
Now install the steering rocker support arm.
The tail box is complete.
Next we will be working with the parts shown here.
Install the steering slider. Take care to note weather or not the brass bushing or "sleeve" is installed inside, between the 2 bearings. Usually they come with the bearings pressed in, but the bushing is not installed.
time to install the blade grip shaft hub. Use plenty of thread lock. Both on the grub screw and inside where the hub mounts to the shaft.
Just like the steering slider. The tail blade grips often come assembled, but with the brass "sleeve" or bushing not installed between the bearings.
Install the blade grips. Be sure to CAREFULLY use thread lock. If you are too liberal with it, it will get into your blade grip bearings. You just need enough to sit between the threads.
Install the aluminum bushings and screw as shown.
Apply thread lock to the blade grip screw hole. Screw down and wipe excess away.
repeat for the other side as well.
Time to install the steering rocker.
Install as shown. Install screw till tip is flush. Put the nut on and tighten the rest of the way. Back off 1/2 to 1 turn. Then tighten the nut down. You want the bottom slightly loose. Nut on top tight.
The assembled tail box with partial tail rotor.
Time to install the blades to complete that tail rotor.
Now it's time to install the tail boom. You may need a coat hanger or something to pull the belt though the boom.
Time to install the servo strut block.
Snap the clips for the rudder rod on the boom. Then get the rudder rod out and install that too.
You want the rudder rod straight. So adjust the clips and snug them down. Not too tight. You may want to move them later.
Install the tail servo mounts as shown.
Time to install the stabilizer fins.
Two screws here in the tail
Two screws here on top of the fin.
Both fins installed.
Time to install the tail boom holder.
you may actually want to keep the boom pushed all the way forward till after the full install is complete. Then you can adjust the tension later. Lately on boom replacements full forward has been good tension anyway.
