Collective Travel for F3C and 3D Flying

*To a11˚ to -10˚ of collective travel range, the steel linkage ball must be moved to the inner

location as shown in the figure.

*You can also flip the pitch servo to get the best configuration.

*Use ATV function of the transmittler to get the necesary servo travel.

The molded "pointer" should line up with the upper limit mark, which

should provide about 11˚ of blade pitch.

For intermediates set the low end to -5˚. For advanced F3C and 3D flying,

set the low end to -10˚.

Mount the steel linkage ball to the outer hole on the plastic throttle arm. At full throttle stick, the
carburetor hole should open completely. At low throttle and with the throttle trim all the way down,
the carburetor hole should close completely. Adjust the ATV function in your transmitter to achieve
the above requirement. Listen to the servo, it should not make any binding noise. Try keep the
throttle ATV between 90% and 110%. If your radio does not have ATV, then adjust the location
of the steel link ball on the throttle servo horn to get the correct throttle travel.

Dear Raptor Customers:

The stock wood blades should be operated with a main rotorspeed of no more than 1700 RPM. For 3D aerobatics
or rotor speed more than 1700RPM, it is recommended to use carbon main rotor blades.  The above drawing
illustrate how to remove the plastic blade grips and then carefully slice away some of the covering material, and
add the "thin" type CA glue to further strengthen the wood.  After installing the plastic blade grips, apply epoxy
around the plastic grip and the wood to seal it off.  This adds more strength and prevent oil from seeping through.
For beginners, the best rotorspeed is around 1550 RPM. For advanced fliers, a good hovering RPM is around
1550, and a constant 1800RPM in idle-up for 3D aerobatics.

3 Main Frame

Assembly-Part1

Please insert the frame spacers, bearings, pulley and parts in the frames according the drawing below. Install four
metal aluminum frame spacers beside the main shaft bearings. Remember add Loctite when securing on these four
spacers. Tighten the screws snugly, but do not over torque them which could strip the plastic.
Insert starter shaft through the center of the clutch bell assembly, through the top starter shaft bearing and into the
starter coupling. Secure with the two set screws. Make sure this is tightly secured.The main frame can be reinforced
by recommended Aluminu Frame Post (PV0104).

      The above pushrod lengths will permit 3D with the Raptor.
Use these lengths as a starting point.  Beginners can also use those pushrod lengths, but just connect the
collective control to the outside point on the pitch control arm.  Pushrod lengths are measured from ball link
center to ball link center.
      Suggested throttle and collective pitch set up:  Idle-up1 is used for continuous 3-D flips and aerobatics.
Idle-up2 is used for switchless inverted hover.  Use a pitch gauge to check blade angles.  It is easier to start
setting up idle-up2 blade pitch angles first.  Beginners should inhibit idle-up1, idle-up2.  Beginners should
only use the Normal mode values.  The model should hover at around 1550 rpm in Normal mode, and flies
at 1800 in idle-up1.  Rotorspeed can be checked using TTR2000 MTF-301 helicopter tachometer.With 1700
or higher headspeed, the use of carbon blades is recommended.

CONFIGURING THE RAPTOR FOR 3D

LINKAGE SET-UP SECTION

[1]The engine will not start.

* The engine starting shaft will not turn:
The engine may be flooded with too much fuel. Please remove the glow plug first, then turn the engine
with the electric starter until the excess fuel spits out of the glow plug hole.

* The engine turns when the electric starter is applied, but the engine will not start:
(1) Is the glow plug working? Remove the glow plug and does the platinum coil glow red when a 1.5

volt battery is applied to the plug? If not, then the glow plug battery may be weak and old.

(2) Is the carburetor needle properly set? Please refer to the engine instruction manual for the proper

needle setting.

(3) Does the throttle control arm move properly and in the correct direction according your transmitter

command?

* Engine will start, but quits immediately.
(1) Use the transmitter to increase the carburetor opening slightly. The throttle stick should never exceed

the 1/3 positiom when starting the engine.

(2) Try a new or different type of glow plug. There are different types of glow plugs on the market for

different types of fuel and operating conditions. Seek the advice of experienced fliers and also
experiment with different types of glow plugs until you find the one that suits your operating condition
the best.

*Engine runs, but the helicopter will not lift off.
(1) Check the main rotor blade pitch angle, they should be set at 5.5 to 6 degrees when the transmitter

throttle/collective stick is at the center position.

(2) Does the engine throttle arm move properly? The carburetor opening should be fully open when

the transmitter throttle/collective stick is moved up.  The carburetor opening should be nearly closed
when the transmitter throttle/collective stick is moved down.  And the opening should be completely
closed when the transmitter throttle/collective stick  is moved down and the throttle trim is also
moved down.

(3) Check your engine manual for proper starting point settings. Then try again to start your engine. If

smoke is excessive when adding throttle your high speed needle may be too rich. Try a few clicks
turning clockwise and try again. Once proper needle settings are achieved, model should lift off
effortlessly.

[2] Helicopter problems.

* The helicopter shakes.
(1) Is the blade spindle bent?
(2) Is the flybar bent?
(3) Is the main rotor shaft bent?
(4) Are the two control paddles mounted at the same distance from the rotor shaft, and the paddles

are parallel to each other, and in the proper direction?

(5) Is the tail rotor shaft bent? The tail rotor blades mounted properly or damaged?
(6) Are the main rotor blades damaged or mounted in the proper orientation? The blades may require

additional balancing.  The blade balance can be checked by removing both blades and then use
one of the 4mm blade bolt and nut to hold the two blades together like a teeter totter.  Then, hold
the blade bolt with your thumb and index finger.  The two blades should teeter and remain in a
level position.  If not, then add some tape to the lighter blade near the blade tip until the two blades
teeter in a level  position.  Hobby shops also sell blade balancers that are designed solely for
balancing model helicopter blades.

After Flight Checklist

(1) Check every screw and bolt to make sure none has loosened due to vibration.
(2) Check every rotating and movable part to ensure they still move smoothly and

normally.

(3) Clean off the exhaust residue from the muffler, engine, and helicopter.
(4) Check all movable parts, such as gears, ball links, belt, etc. for unusual wear.

THROTTLE FULLY OPEN

THROTTLE CLOSE

The performance of any RC helicopter and how well it fly depends strongly on well the model has been
set up.  We will go through the step-by-step on how to set up the transmitter and mechanics linkages
to make your Raptor 50 fly at its best.  Before you start, please make up the length of all the pushrods
according to the recommended length given in our 3D setup drawing in the instruction manual.  The
pushrod lengths we have provided are valid for beginners to expert 3-D flying.  Then, we recommend
using the reset function on your transmitter to reset all settings to factory default values.  Check the
end point adjustment, or ATV value, on your transmitter to make sure the values are at 100%. Next
we recommend program the numerical values we have provided in the table for the five points in the
throttle curves and for the collective pitch curves.  Now you can proceed to do the mechanical adjustments.
We recommend leave the transmitter on during the following adjustments.

1.Throttle Adjustment.

The throttle arm on the carburetor should always be parallel to the throttle servo arm.  When the throttle
barrel is half open, the throttle arm should be straight down.  Leave it at this position.   Turn on the
transmitter and leave the throttle in the Normal Throttle Mode.  Set the throttle trim to the bottom and
set the throttle stick to the middle.  Adjust the throttle pushrod to the correct length.   Check the throttle
servo travel direction to confirm moving the throttle stick to the high position will move the throttle arm
to the full open position.  Use a medium length servo arm.  Pick a hole on the servo arm so when the
throttle stick is moved to the highest or the lowest position, it will fully open or fully close the throttle
arm without binding.  Now is the time to use the End Point Adjustment or ATV feature on the transmitter
to fine tune the throttle servo travel to achieve this. Avoid using too large or too small ATV values.
The ATV values should stay between 90 to 100%.

2.Collective Pitch Setup

Collective control makes a helicopter ascend or descend by changing the main rotor blade angle.
Beginners and advance fliers must attach the collective control pushrod to different locations on the
collective control arm. The difference is that advance fliers desire more collective travel range, usually
+10 to -10 degrees of blade change range. Beginners only need -2 to +10 degrees of blade change
range. We assume you have programmed in our recommended values from the Table for the throttle
and pitch curves.

Collective Setup for Beginners:
Only the Normal Throttle Model will be used.  We recommend using a collective pitch range of -2 to
+10 degrees.  Move the throttle/collective control stick to the center.  Attach the servo arm so the servo
arm is in a horizontal position.  The servo output shaft has spline. Try mounting the servo arm with
different orientation until one of the arms becomes as close to horizontal.  Attach the steel ball to the
collective servo arm at about 15 mm from the center of the servo arm. Move the throttle stick to the
middle position.  Tilt the collective control arm/tray assembly so it is approximately in the middle of its
allowable mechanics tilting range.  Use the molded pitch scale on the left side of the plastic frame.
The pointer on the collective arm should point to the mark for the hover position.  See our drawings of
the molded scale in the other section of this manual.   Attach the pushrod.  The pushrod length should
be 51 mm as recommended in the drawing.  Use a pitch gauge to check the blade angle, they should
be about 5.5 degrees. This is what you need for hovering. This gives a hovering rotor rpm around
1500.

Radio and Control Linkage Setup For Raptor 50

Move the throttle stick to the high position to check if it causes binding.  Move the throttle stick to the
low position to check if it causes binding.  The blade should be at 10 degrees at full collective control
stick setting, and -2 degrees at idle stick position.  Use the ATV or End Point Adjustment to eliminate
binding, or to make the pitch come out at +10 and -2 at the extremes.

Collective Setup for 3-D:
We recommend using a collective pitch range of approxi10 to +10 degrees in the Stunt mode,
or idle-up mode.  Use approximately -6 to +11 degrees in the Throttle Hold Mode.  Please see the
table of pitch angle values we have provided for 3-D flying.  To set up the collective for 3-D or F3C
flying, we recommend starting with Idle-up Mode,  or Stunt Mode.  Increase the ATV  or End Point
Adjustment of the collective channel to 130%.  Attach the steel ball to the collective servo arm at about
15 mm from the center of the servo arm.  The pushrod should be around 54 mm long.  Move the throttle
stick to the center position and mount the servo arm so the arm is in a horizontal position.  Move the
throttle stick to the high position to check if it causes binding.  Move the throttle stick to the low position
to check if it causes binding.  The blade should be at 10 degrees at full collective control stick setting,
and -10 degrees at idle stick position. Use the ATV or End Point Adjustment to eliminate binding, or
to make the pitch come out at +10 and -10 at the extremes.

After you have done the above and obtained the +10, 0 and -10 degree collective travel range in idle-
up, you will automatically get the proper collective settings for the Normal Throttle Mode and Throttle
Hold Mode. This is because you have programmed in the numerical values we have provided in the
table.

If the throttle was set up according to described earlier, and the numerical values for the five points
from the table have been programmed into the transmitter, you will get the proper U-shaped throttle
curve for 3-D flying.  We have left the values for idle-up 1 and idle-up 2 the same.  Individual fliers
can refine the two Idle-up setting to suit the need for different 3-D and F3C maneuvers.  With Idle-up
on, the main rotorspeed should be around 1700 to 1800 for good 3-D flying. We recommend using
only carbon graphite main rotor blades for aggressive 3-D flying.  Please try the Thunder tiger 600
mm carbon graphite rotor blades, they are designed for extreme 3-D flying with the Raptor 50.  Wood
main rotor blades are fine for learning how to fly or for practicing simple maneuvers.

3.Cyclic Control Setup

Cyclic controls consist of fore/aft cyclic and left/right cyclic.  Fore/aft cyclic is often called elevator control.
Left/right cyclic is often called aileron control.  Elevator and aileron controls are terms used by airplane
pilot.  Set the cyclic control stick of your transmitter in the middle and set the trims to the center.  Put
the swashplate in a level position.
Fore/Aft Cyclic Setup:  Attach the elevator servo arm to elevator control servo.  The servo arm should
point straight up.  We recommend attaching the steel ball to the elevator servo arm at about 10 mm
from the center of the servo.  Adjust the pushrod length from the elevator servo to make the swashplate
level.

Left/Right Cyclic Setup: Attach the aileron servo arm to aileron control servo.  Mount the servo arm
so the servo arm is close to perpendicular to the servo case.  We recommend attaching the steel ball
to the elevator servo arm at about 10 to 12 mm from the center of the servo.  Adjust the pushrod length
from the aileron servo to make the swashplate level.  The two pushrods from the aileron servo to the
aileron bellcrank should be very similar in length.

4.Tail Rotor Control and Gyro Setup

The radio setup for using a heading hold gyro and a non-heading hold gyro will be different. But the
mechanical setup will be the same.

Heading Hold Gyro Setup: Set the tail rotor mixing or revolution mixing values to zero for every throttle
mode in the transmitter. Leave the tail rotor control stick in the center and move the tail rotor trim on
the transmitter to the center. Attach the servo arm so the arm is straight up. Mount the steel ball 10
to 12 mm from the center of the servo arm.  Attach the tail rotor pushrod rod.  The pushrod will require
a small 15 degree bent to give a smooth run.  See the 3-D setup drawing.  Adjust the pushrod rod
ball links so the tail rotor blade angle is approximately 15 degree.  Check the tail rotor control direction
so a right tail rotor command should increase the tail rotor blade pitch angle.  A left command reduces
the angle.  Leave the tail rotor control channel ATV at 100%.  Use the hand and rotate the gyro to the
left should cause the servo to provide a right tail rotor command (increases the tail rotor blade pitch
angle).  Rotate the gyro to the right should cause the servo to provide a left tail rotor command (reduces
the tail rotor blade pitch angle).  If the gyro is providing the wrong feedback, then the gyro needs to
be mounted upside down or some gyro has a reverse switch on the gyro box.  Never use any tail rotor
revolution mixing when using a heading hold gyro, that causes the gyro to drift.  Never use any tail
rotor trim when using a heading hold gyro, that causes the gyro to drift.

Non-Heading Hold Gyro Setup: Leave the throttle stick and tail rotor control stick in the center and
move the tail rotor trim on the transmitter to the center.  Attach the servo arm so the arm is straight
up. Mount the steel ball 10 to 12 mm from the center of the servo arm.  Attach the tail rotor pushrod
rod.  The pushrod will require a small 15 degree bent to give a smooth run.  See the 3-D setup drawing.
Adjust the pushrod rod ball links so the tail rotor blade angle is approximately 15 degree.  Check the
tail rotor control direction so a right tail rotor command should increase the tail rotor blade pitch angle.
A left command reduces the angle.  Leave the tail rotor control channel ATV at 100%.  Use the hand
and rotate the gyro to the left should cause the servo to provide a right tail rotor command (increases
the tail rotor blade pitch angle).  Rotate the gyro to the right should cause the servo to provide a left
tail rotor command (reduces the tail rotor blade pitch angle).  If the gyro is providing the wrong feedback,
then the gyro needs to be mounted upside down or some gyro has a reverse switch on the gyro box.
Go to the tail rotor revolution mix function in the transmitter. Put in a numerical value of +25 for the
high end revolution mixing and -30 for the low end revolution mixing.   Move the throttle stick to the
high position and you should see the tail rotor servo moves and "increases" the tail rotor blade angle
from 15 degrees to about 25 degrees. Move the throttle stick to the low position and you should see
the tail rotor servo moves and "decreases" the tail rotor blade angle from 15 degrees to 0 degrees.
This is to compensate for the change in torque on the helicopter fuselage when collective pitch is
changed.  A heading hold gyro does not need tail rotor revolution mixing because it automatically senses
heading change and feed in command to lock on the helicopter "heading." A non-heading hold gyro
can only stabilizes the "rate" that the helicopters nose is rotating.

For 3-D flying with a non-heading hold gyro, it will be necessary to put in a V-shaped tail rotor mixing
curve. Try +15 for the high end revolution mixing and +15 for the low end revolution mixing.

Note: After assembly, check to make sure the Fuel Tank
clunk can move from top to bottom without touching the
back of tank. Also, a fuel filter (available from any hobby
shop, TTR1165C) should be placed between the fuel tank
and the carburetor.

It might be necessary to inspect and replace the silicone
tube inside the tank every month to ensure the fuel

12 Flybar Assembly

Begin by attaching six Linkage Balls to the Flybar Control Arm and Mixing Lever with Self Tapping Screw. Slide
Flybar Arm Bushing and Flybar Control Arm onto the Flybar Rod. From the other end of the Flybar Rod, slide on
the Flybar Seesaw Hub. Make sure the Flybar has equal protruding from each side of the Seesaw Hub, then install
and tighten the HME4-5B set screws. Add the Paddles. Make sure the two Paddles and the two Flybar Control Arms
are all parallel. Lock the Paddles with HME3-10B set screws.
Attaching four Linkage Balls to the Mixing Levers first. Then assemble and install the Mixing Levers ,Bearings and
washers using Collar with Socket Screw. Be careful don’t let the Loctite seep into the bearings.
Attach the Bearings into the Main Rotor Hub. Insert and tighten the Set Screws. Attach the Flybar Control Rod to
the Flybar Control Arm and use the Double Link to connect the mixing Lever (short side) to the Main Rotor Pitch
Housing.
Note:The equipped with Paddle is good for stable and beginner flying. For those aggressive 3D pilots, we would
recommend our optional light 3D Paddle (PV0481) or ultra light Paddle (PV0482) which weights only 25g and 20g.

Assembly Tip: Slide the 3 rod guides onto the boom and space them out evenly as shown. Then slide the tail linkage
rod into the rod guides. Next, insert the tail rotor drive belt into the boom so that it comes out of both ends. Place
drive belt over tail drive pulley and complete balance of tail boom assembly. Remember to connect the tail linkage
rod to the tail control lever. Apply thick CA or Epoxy when installing Tail support Rod End.

Pull the belt through the tail base, keeping the belt correctly aligned.  Push
the tail boom into the tail base all the way to the end. Place the drive belt over
the tail drive spur gear.  Then, gently pull back on the tail boom until the tension
on the belt allows no more than 5mm(3/16") of free play in the belt.  Tighten
the locknuts and proceed with the rest of the assembly.

Install the header tank and secure the mount with socket screw, washer.
Connect the fuel tube properly.

Insert the M3x20 and two M3x25 socket screws with meatal Rear Servo Plate into the tail base of the Main Frame
and secure with lock nuts.

Do not tighten at this point.

Hold the tail boom in one hand and hook your index finger on your free hand through the exposed loop of the tail
rotor drive belt. Hold it so the belt is vertical and parallel to the tail drive pulley.

Next work on the housing assembly, use care to install the Tail Pitch Control Link, do not over tighten the selftapping
Screw(#2). Make sure it is just tight and the link rotates freely.
Assemble the Tail Pitch Slider and Fork. Be careful when securing the Fork on the slider bushing, do not damage
the bushing or it will not move smoothly on the tail rotor shaft.
