Next comes the tail. Again the tail assembly is pre-done at the factory. Thread the belt through the tailboom, and install the tail assembly onto the boom. There is a small plastic piece on the tail assembly clamp area which needs to be removed during assembly so the tailboom can slide in. The notch on this plastic piece prevents the assembly from rotating on the tailboom. Once fitted, the horizontal fin mount, pushrod guide, and rudder servo mounts will be fitted onto the tailboom. I don't know how many time I forget this step and had to remove the tailboom.

Then the boom is fitted onto the main frame. Loosen up the 8 screws on the frame's boom clamps to facilitate the boom installation. Twist the belt 90 degrees counterclockwise and loop over the drive pulley. Pull tight and tighten the 8 screws to clamp the boom in place.

The rest of the steps includes the installation of boom supports and tail fins. I choose to install the tapered blades for initial flight test.
