Trex 500 RC Helicopter Tail Boom Clamp

Installing the trex 500 rc helicopter tail boom clamp is a relatively straightforward affair. The front pulley should be installed into the bearing recesses molded into the clamp. Don't forget to thread the belt around the pulley before fitting it into the clamp, it is not possible to fit the belt once you have closed the tail boom clamp around the front pulley. Once the front pulley is installed the belt can be threaded through the hole where the tail boom will insert. You can now screw the tail clamp into place between the side frames. Make sure you install the pulley the right way up as there is nothing to stop it being installed upside down.

Trex 500 RC Helicopter Main Gear

The trex 500 rc helicopter manual shows the main gear assembly but in reality it comes pre-assembled by the factory. All that is required is to slot it into the main frames and then push the previously assembled rotorhead down through the bearing blocks and through the hole in the center of the main gear. Then it is a simple case of lining up the holes in the main shaft and main gear and installing the supplied bolt and nyloc nut. Do not over tighten the nut as it will warp the main gear.

Now is also the time to set the mast locking collar of trex 500 rc helicopter correctly. The rotor head and gear should be pulled upwards and the mast locking collar pushed down onto the top bearing block and the set screw tightened. This then removes any vertical movement in the main shaft and keeps the main gear in the correct position.

Trex 500 RC Helicopter Tail Boom & Tail Gearbox

Installing the trex 500 rc helicopter tail boom is a simple matter of pushing it into the tail boom clamp, it has a slot to locate it correctly. However, before this can happen the belt must be threaded through the boom. I usually tie a bit of string to the belt, thread through the boom and then pull the belt through. With the boom in place thread the tail servo mount and the two tail push rod guides onto the boom.

Now we can build the tail gearbox of your trex 500 rc helicopter. This requires the two tail cases and the tail output shaft and pulley. In order to install the tail output shaft the belt must be given a quarter twist as shown in the manual and then the pulley and output shaft placed onto the trex 500 rc helicopter belt. The two tail cases can then be closed around the tail output shaft and the three bolts and nuts installed and tightened. Check the output shaft direction, it should rotate anti-clockwise when you rotate the rotorhead clockwise. Now is also a good time to set the belt tension and do up the two screws securing the boom into the clamp.

Trex 500 RC Helicopter Tail Rotor & Fins

Installation of the tail rotor involves installing the tail pitch slider and it's control horn as well as the tail rotor hub and blades. Fitting the fins of the trex 500 rc helicopter comes after this.

First the tail pitch slider should be slid onto the tail output shaft followed by the tail hub. This can be secured in place by the set screw in the tail hub of your trex 500 rc helicopter. Don't forget to loctite this set screw. Also, remove the tail blade bolts and loctite them so the blade grips don't come off of the hub.

With the tail rotor in place orientate the blade grips so that the hexagonal nut retainer on the blade grips is to the rear (facing the tail gearbox). The pitch slider can now be secured to the grips using the brass bush and small cross head screws provided.

Lastly the control horn of the trex 500 rc helicopter can be secured into place. This has a washer under the screw head as well as between the control horn and the plastic gearbox mount point. Align the pitch slider ball with the horns hole and then screw it tightly into place of your trex 500 rc helicopter. Make sure you don't over tighten and that it all moves freely. Lastly bolt the horizontal and vertical fins into place and fit the tail boom supports.
