Step 24 Final Rotor Head Assembly

Following assembly, move the swashplate up and down to the endpoints. The swashplate and washout

unit should be very smooth throughout the movement range. If not, inspect the fit of the washout guide to

the pins in the rotor head, these pins can be bent slightly if binding. Lastly the fit of the ball links some-

times can cause binding. These few points are the most common which will cause servo strain leading to

premature wear and will appear as a jump in altitude when flying the helicopter.

Slide the washout assembly from Step 6 onto the main shaft. Slide the nylon sleeve over one 3x15mm

Socket Cap Screw and insert through the anti-rotation bracket into the remaining open hole in the

swashplate using threadlock. Slide the completed rotor head assembly from Step 5 onto the shaft and

align the hole in the head block with the hole in the top of the main shaft and insert one 3x20mm Socket

Cap Screw and 3mm locknut (from Bag 2) to secure the two. (Note: Make sure the pins in the rotor

head block are aligned and inserted into the holes in the washout unit.) Apply some oil spar-

ingly to the washout hub assembly to insure they slide smoothly.

Packaged with the tailboom is the carbon torque tube drive shaft assembly. The is a complete assem-

bly ready to be installed into the helicopter. Using a light oil, apply a few drops to the ball bearing

inside the tailboom guide. This should be done every 20 hours of flight or 3 month intervals. Insert the

drive shaft assembly into the tailboom from the end with the 2 holes and position the assembly approxi-

mately centered in the tailboom (apply a little liquid hand soap to ease the insertion of the o-ring

guides ). Using one half of the tail gearbox assembly with the tail input shaft installed, continue

to insert the drive shaft assembly until there is a 1mm gap between

the end of the drive shaft and the bottom of the drive

coupler. This is simple with the gearbox open, make

sure the tailboom is properly keyed

into the tail gearbox. Slide

the three tail pushrod

guides onto the

tailboom engaging

tail pushrod. Thread

the pushrod connector

onto the long pushrod,

the short ‘z’ pushrod will

be attached in the

rudder servo linkage

setup page.

Having taken time to properly fit the tail gearbox joint will make the front transmission

assembly very simple.

Reminder, after radio set up is complete, glue the pushrod

guides using a single drop of Zap Ca. One drop will stop the

pushrod from binding and still be able to remove them later.

If not already done, slide

the three tail pushrod

guides onto the tailboom

engaging tail pushrod.

Attach the pushrod

connector and the short

“z” pushrod. Align the

guides as illustrated in the

picture until the pushrod

can be moved very

smoothly by hand. Once

satisfied bond in place

with a single drop of Zap

Ca. (one drop will allow

easy removal later).
