Raptor 60 Construction Notes

From: Tony Groothuizen
Step 1-1

I started by gluing the clutch liner to the clutch bell, and reading the
manual while the epoxy cured. Yes, I did pull out the clutch, put on a
single wrap of electrical tape, and use it to form the liner and hold it in
place.

Start by putting the pinion gear subassembly together.
- Screw the Drive Pinion into the Clutch Bell
- Place the large bearing over the Drive Pinion, and
secure with the Pinion Gear Nut.

Put the six Frame Spacer S's for the Pitch Guides aside
Put the two Frame Spacer M's for the Upper Frame Assembly aside
Put the two Button Head Socket Screws for the Upper Frame Assembly aside

Install these when you mount the Upper Frame Assembly to the Lower Frame
Assembly in step 1-3. I found that these parts kept dropping out of their
respective assemblies.

Pull the Pinion Gear Subassembly as far forward as possible, and leave the
Socket Screws, snugged without locktite. This will be adjusted later.




Step 1-2

Leave the Socket Screws for the Lower BRG Subassembly snugged without
locktite. This will be adjusted later.


Step 1-2-2

Using a 12pt deep socket and a soft mallet, tap the first bearing onto Tail
Drive Bevel Gear B. Test fit with the Tail Boom Brackets and Tail Drive
Bevel Gear A subassembly frequently, until you achieve a smooth rotation,
with no slop. Repeat to install the second bearing onto Tail Drive Bevel
Gear B.


Step 1-2-4

A little Vaseline on the Fuel Nipple lets you slide this into Fuel Tank
Stopper without driving it into the Fuel Tank.

Step 1-5

You can remove the forward Socket Screws from the Upper Bearing Subassembly,
and swing this out of the way, if you have problems installing the Elevator
Control Arm Subassembly.



Step 1-6

The Main Spur Gear is fitted with the raised center ring up.

The diagram on page 15 shows four BK0087 d3xD8x1.4 washers. These are not
supplied or mentioned in section 1-6-3 (Main Gear Subassembly)

Loosen the Socket Screws Slide on the Lower Bearing Assembly, and move this
to achieve a smooth slop-free mesh of the Tail Drive Spur Gear with the
Tail Drive Pinion Gear. Tighten the Socket Screws Slide on the Lower
Bearing Assembly, re-test and re-adjust as required. Repeat the above with
the Pinion Gear Subassembly to ensure a slop-free mesh of the Drive Pinion
with the Main Spur Gear. I'll locktite to the Socket Screws involved after
the first few flights. I'll check these after each flight until I do.


Step 2-1

Build two subassemblies, the flybar, and remainder of the Rotor Head.
- Start by fitting the link balls to all parts
requiring them, this uses up 16 of the smallest
parts fast.
- Build the Flybar Subassembly, flat edge of the
mixing levers goes down.
- Build the Spindle Subassembly, raised collars
on the Flap dampers face out. A little grease
lets the Spindle slip through easily. (I used
Vaseline)


Step 3-1

Use a deep socket and one of the Tail Support Rods to push the Tail Drive
Shaft Bearing into place. Don't fasten the rod Guides to the Tail Boom
with CA until you have installed the Tail Rotor Servo.

Step 3-1-1

Build the Tail Case and internals subassembly first. Attach the Tail Output
Bevel Gear to the Tail Shaft. Using a 12pt deep socket and a soft mallet,
tap the first bearing onto Tail Input Bevel Gear. Test fit with the Tail
Cases and Tail Output Bevel Gear Subassembly frequently, until you achieve
a smooth rotation, with no slop. Repeat to install the second bearing onto
Tail Input Bevel Gear.
