Airfield Models ( the Thunder Tiger Raptor 30 V2 Helicopter Step Three


Step Three Main Frame Assembly - Part One

  • This step is on page 6 of the Instruction Manual.
By the end of this step the frames will be joined having everything in between that must be added beforehand.
Parts for frame assembly. The parts needed for this step.  Put the fuel line aside for now.  We won't add it until the helicopter is built.
Plastic hex posts that hold the frames together. You'll notice that there are two lengths of frame posts.  There are four long posts and eight short posts.
Locations of the four long plastic posts. These are the locations of the long posts.
Idle pulley assembly. Assemble two guide pulleys.  These pulleys push the tail rotor drive belt together so that it doesn't rub on the frame or tail boom.

Place a collar on the pin, slide the pin through the pulley and then push a collar on the other end of the pin.

Idle pulley mounted in a frame half. The pulleys are located just in front of the tail boom.  Stops are molded in that will prevent the pin from coming out.

One pulley goes in each half of the frame.

Remaining posts mounted in a frame half. The pulley and all of the posts in place.  You can screw the frame to the posts now or wait until the second frame half is in place.
Main shaft and start shaft bearings. These three bearings must be in place before the frames are joined.

The two larger bearings are for the main shaft.  The smaller bearing is for the starter shaft that engages the clutch.

Main shaft bearings mounted in a frame half. The main shaft bearings.
Start shaft pieces. The starter shaft.
Put an E-clip in the groove on the start shaft. Place an E-clip in the groove cut into the starter shaft.
Slide the washer up to the E-clip from the long end of the shaft. Slide the washer up to the E-clip.
Insert the long end of the shaft into the clutch bell. Slide the starter shaft into the clutch bell with the E-clip and washer inside the bell.
Slide the second bearing onto the start shaft. One bearing is already on the drive gear.  Slide the second bearing on.
Starter coupling and set screws. Clean the end of the starter shaft with alcohol.  Also clean the set screws and starter coupling.

The starter coupling allows a 6 mm hex shaft to be used in your electric starter to start the engine.

The starter shaft has two flats on the end for the set screws to engage.

Put Loctite on each of the two set screws and insert the screws into the starter coupling just a couple of turns.

Starter coupling on start shaft. Slide the starter coupling onto the starter shaft and tighten the set screws lightly against the flats.

After the frames are bolted together, loosen the set screws slightly.  Push the starter shaft up against the inside of the bell.  Push the starter coupling down until it touches the bearing.  Securely tighten the set screws.

Oil the shaft using a light oil.

Start shaft assembly and fuel tank inside a frame half. Place the clutch bell/starter shaft assembly in the frame.

Add the fuel tank.  The fuel tank has two molded protrusions that engage the frame.  You'll see where they are when you get there.

Second frame screwed in place. Align the second half of the frame and slide it onto the posts.  Screw both frames to the posts.

Be gentle when tightening these screws.  They will not come loose on their own.  If you tighten them too much the plastic will strip.

The servo frame is placed between the frame halves in front. Insert the servo frame and screw it in place from both sides.
Three screws through each half of the frame hold the radio tray in place. These are the three screw locations that hold the servo frame in place.
The completed frame assembly. Part one of the frame assembly is complete.
