Thank you very much for purchasing the Thunder Tiger Raptor 90 3D R/C helicopter. The design of Raptor

90 3D is based on the original Raptor 90 series helicopter and modified for extreme aerobatics. It has all

needed must-have optional parts for 3D flying, such as metal main rotor hub, non-linear flapping damper,

metal BRG, 3D light paddles and so on. It also adopts the push-pull control system on collective pitch

and elevator to achieve the most precise control. The flybar ratio is changeable to fit all kinds of flying

style. Use of high quality material make the helicopter one tough machine that can handle everyday 3D

beating. Raptor 90 3D is born for 3D flying, and you don’t have to do any further modification for aggressive

3D maneuver. This is by far the best machine you have never seen. Just enjoy the model and have fun.

UNIQUE SIDEFRAME SYSTEM

Aluminum side plates are used in conjunction with molded material to construct the main structure. This

design produces minimum weight with maximum strength. If the sideframes were completely made of

molded material, then to achieve equal strength the plastic would have to be very thick and heavy. Using

molded material at the right place avoids using metal angle brackets or putting compound bends in metal

frames. Slots have been added in the frame design to permit the use of optional gear ratios to optimize

engine performance to suit any pilot's demand.

BELL-HIILLER MIXING CONTROL UNIT

Main rotor control geometry has been carefully engineered to minimize cross-coupling in collective and

cyclic commands. Blade pitch arms and the Bell-Hiller mixing arms are designed at an angle such that

the pushrod interlinking them are at 90 degrees when the blades are at 0 degree. The pilots will get the

symmetrical cyclic control feel and flybar authority either at +10 or -10 degrees of collective. We design

this system with the 3-D pilot in mind. We guarantee you this whole design philosophy provides a strong

and accurate control mechanism.

SHAFT DRIVE TAIL ROTOR

The Raptor 90 3D is designed with a constant drive tail rotor system to permit full tail rotor control during

autorotations. 180 autos, backward autos and pirouette autos are all within your reach now. It has the

same aluminum torque tube system as the Thunder Tiger/Taya Imperio helicopter. This allows obtaining

the maximum performance from any modern heading lock gyros.

3D CAD DESIGN

We use the latest 3D Computer Aided Design to design and manufacture the Raptor 90 3D. Our high-

tech CAD program allows simulation of all moving parts to ensure no interference. The analysis automatically

analyze the weight, the mass distribution, and inertia to help us pursue a design that will provide the high

level of maneuverability needed for all-out 3-D aerobatics.

When installing pinion gear, add a small drop of Loctite to the

threads. Make sure not to get Loctite on lower clutch bell bearing.

Important:

For 90 class engine, we recommend the 11 teeth pinion for 3D

flying.

The servo tray and cooling fan shrouds on the Raptor 90 are different from the

Raptor 60 in order to accommodate the full head sink on the O.S 91. engine.

If using T.T 90, Y.S 91 or Webra 91 engine, make sure to install the fan shroud

baffle with two self-tapping screws. This will ensure optimal cooling of your engine

head.

Please complete subassembly steps 1-2-1 through 1-2-3 first. Then attach the subassemblies to the two Lower Frames. Note

that the Metal Lower BRG is installed with the bearing open side facing up. Please add a small drop of Loctite on every bolt

before screwing it into the aluminum hex spacer. Do not apply Loctite to the bolts which are going to secure the Lower BRG

Block at this moment.

Assemble the upper main frames by starting with the two Metal Upper Frames. The Pinion Gear Subassembly must be assembled

first according to Figure 1-1-1. Next insert three hex-shape frame spacers into the plastic Pitch Guide according to Figure 1-1-2

and 1-1-3. Assemble the Elevator Control Arm subassembly according to 1-1-4. Insert it in between the two Upper Frames. The

metal Elevator Control Arm is not symmetrical. The side with the longer profruding round knob should be on the right side of the

helicopter. Then attach the other subassemblies to the Upper Frames. Locate Hex Wrenches in BAG L which you need for

assembly.

Please add a tiny drop of non-permanent type Loctite on the tip of all bolts before screwing them into the hex shaped aluminum

frame spacers. Never use too much Loctite, otherwise it will become nearly impossible to remove later on for servicing. Only use

the non-permanent type of Loctite. If encountering difficulty in removing any bolt that was locked up by Loctite, heat up the head

of the screw or bolt with the tip of a hot soldering iron, it will help soften the cured Loctite.

For the kit, parts are bagged according to each major assembly and are labeled "Bag A, Bag

B, etc." The heading for each assembly indicates which bag to open. As a go od practice,

only open up the bag that you need for the particular assembly. Check the parts in that bag

against the parts list shown for each assembly as well as each sub-assembly to make sure

there are no missing parts. To prevent losing small hardware, please empty the small nuts

and bolts and parts into small plastic trays on your work table. At the end of each major

assembly, there should be no left over parts.

The fuel tank comes assembled from the factory because every tank has been

checked for leak. If you were to take the tank apart here is how to put it back

together. Install the silicone fuel line to the Fuel Nipple. Then add the rubber

fuel tank stopper and the clunk weight. The stock silicone fuel line is very soft

and thin which is designed to allow the clunk to pick up fuel easily during 3-D

aerobatics. The pickup line should be inspected and replaced if necessary every

month, otherwise when it becomes soggy it can break off. A thicker silicone line

maybe substituted but make sure the clunk will reach the bottom when moving

the fuel tank to all different orientations.

As show in Figure 1-3-1, insert two hex

Frame Spacers S into the plastic Rod

Guide Collars. Then join the Upper

Frame Assembly to the Lower Frame

Assembly according to drawing 1-3.

Secure the Set Screws (No.1) to the

frames, and fit the Body Posts (No.4)

to the Set Screews. The two Body Posts

will be used to secure the canopy in the

future. Add Loctite on all bolts and

inside BK0103 threaded hole.

Install the one-piece servo frame with six self-tapping screws.

Do not use Loctite when attaching self-tapping screws to plastic

parts. Loctite is only for threading metal into metal parts. Assemble the constant drive Main Gear Subassembly according to Figure 1-6-2 first.Then build up the Wash Out Subassembly

according to 1-6-1. Insert the No.3 Main Shaft into the bearings and then add the No.4 Lock Ring and slide in the Main Gear

Subassembly.Add two M3x6 Button Head Screws to the Locking Ring, and the two screws are threaded into the holes on the

main rotor shaft.

The locking ring prevents the main shaft from sliding up. Line up the hole on the main gear and the main shaft, then insert M4x2 5

mm Bolt through them. Place a 4 mm M4 locknut on the other side of the autorotation hub, and then tighten the Bolt. Do not

over tighten the Bolt, otherwise the autorotation assembly will be distorted. Loosen the 3mm bolts holding the Upper and lower

bearing blocks for the 12mm main shaft. Wiggle the main shaft in the bearing blocks until the main shaft spins freelyin the bea rings.

This ensures the upper and lower bearing blocks are aligned. Push the lower bearing block up until the mainshaft has no up

and down play.Then tighten the 3mm bolts for the upper and lower bearing blocks.

Insert the pin into the Washout Link.Add a tiny drop of Loctite on the inside

and outside of BK0409 Collar which will help give a completely slop free

control system. Do not let the Loctite seep into the bearing.Adjust the

tightness of the M3x12 bolts so the mixing arms can move freely but without

wobble or racheting the ball bearings.Add a tiny drop of thick CAglue at

the tip of the M2x10 self-tapping screw (No. 1) before screwing it into the

Flybar Control Levers (No. 6).

Make the two pushrods for controlling the blade pitch.The distance 43 mm is measured between the center of two pushrod holes.

Attach the Seesaw Hub of the Control PaddleAssembly to the Main Rotor Head with Socket Screws (M3x10).

Please add a small drop of Loctite along the entire length of the M3x10 Socket Screw (No.5) and on the outside of the collar

d3xD4x5.5 (No.3).Temporarily install the Washout Base Guidence Ring, but do not tighten the No.6 M3 Socket Screw yet.

Assemble the tail transmission subassembly according to 3-

1-1 and 3-1-2 first. And the tail drive shaft subassembly according

to 3-1-3.But do not close the two halves of the tail transmission

tightly. You will do this when you are ready to install the gearbox

onto the tail boom.

When installing the tail transmission, make sure the housings

match the hole on to the tail boom. Add Carbon Vertical Fin with

machined washer and Locknut, then tighten the five 3 mm bolts.

Add carbon Vertical Fin with Pom washer and Locknut.

Before inserting the finished tail drive shaft assembly into the

tail boom, add some flexible silicone glue or ZAP Goop glue

around the outside of the tail drive bearing housing. This will

prevent the bearing housing from spinning inside the tail boom.

(7)

Install bearings No. 2 and No.3 into the Tail Cases. Install No.

16 Tail Bevel Gear onto the Tail Shaft. Gently tap the No. 17

Pin into the Bevel Gear and Tail Shaft. Then secure the pin

with a No. 7 Set Screw with Loctite.

After installing the M3x4 set screws, try pushing on the 2x12

pin with a small Allen wrench to make sure the set screw has

locked the pin in place securely. Before closing the two halves

of the Tail Cases, please check the gear mesh between gears

No. 15 and No. 16. If the gears mesh too tight, then a 5 mm

i.d. washer should be added to move the gear No. 16 further

out. If there exists too much freeplay, then a 5 mm i.d. washer

to push gear No. 16 closer to gear No. 15.

Install the No. 12 Tail Pitch Control Lever as shown with No. 6

Slide four No. 6 Rod Guides onto the tail boom. Do not glue

them onto the tail boom yet. Add a tiny drop of CA glue to the

pushrod guide after you finish building the entire helicopter.

Before adding glue, make sure the tail pushrod is hooked up

to the servo and the rod travels in a straight line and moves

very smoothly.

Congratulation, we are almost done. Install the finished main

rotor head onto the 12 mm rotor main shaft. Secure it with a

M4x20 Bolt and M4 Locknut. Make up two 113.5 mm long

pushrods and attach them to the Bell-Hiller mixing arm.

Before installing the plastic end caps, please

add a drop of slow, thick CA glue on the

rim of the end caps and on the inside edge

of the aluminum skid.

Slide the finished tail boom into the helicopter.The four bolts

on the helicopter must be loose in order to insert the tail boom.

Make sure the tail drive shaft is inserted into the front receptacle

properly. Check this by turning the main rotor head. Secure

Secure the two ends to the rod with Epoxy, making sure the

two metal ends are perpendicular to each other.

(4)

Attach the engine into the side frames, with four M4x12 bolts and

four washers, but do not tighten until Section 6-1.

Install the muffler after you have building the entire helicopter.

Always add Loctite on the muffler bolts.

Install the servos and make up the pushrods according to the drawings.The distance between the steel ball and the center of

servo arm are shown in the drawing. Use them as a guide.These distances are used in conjunction with the servo travels (ATV

or End point) set to 100% for all the channels in the transmitter.Tune them later on to suit your personal flying style.

Attach the rudder servo to the rear mounted carbon plate with four 2.6mm bolts and four M2.6 locknut.

Make up the throttle and collective control pushrods according

to the drawing. Use the outermost hole on the carburetor throttle

control arm.Attach the steel ball on the throttle servo arm at

approximately the same distance as the steel ball on the throttle

arm.

Make up the throttle at 97.5mm long first, and then adjust the

pushrod length and throttle servoATV or Endpoint so full throttle

stick command will open the carburetor barrel fully.And full low

stick and low throttle trim will close the carburetor barrel completely.

Install the receiver and receiver battery. Even though the receiver and battery can be attached to the helicopter tray by using

double sided foam tape, but it is better to wrap the receiver and battery separately using half inch or 10 mm thickfoam. Then

secure them to the tray using six to eight rubberbands, or Velcro bands.

Carefully cut out the canopy (windshield) using scissors.The

best scissors to use are (TTR 1304) designed to cut RC car

bodies and Canopy. Install the canopy to the body using six

small screws. Drill small holes in the canopy and body for the

holes. Drill two more holes for the rubber grommets.

them with a ruler, then install and tighten the No.8 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 No.6 set screws.

Assemble and install the No.10 Mixing Levers and No.5 Bearings according to the drawing using No.12 Collar andNo.9 d3xD5x0.5

washer.

Note:Before installing the Mixing Lever (No.10), please add a small drop of Loctite along the entire length of the M3x18 button

head socket screw (No.4) and on the outside of the collar d3xD4x13 (No.12). Be careful do not let the Loctite seep into the bear ings.

There are two choices of hole positions on the aluminum seesaw for attaching the mixing lever arm.The outside hole gives higher

Bell-Hiller mixing ratio. For aggressive 3D flying, you can attach the Bell-Hiller mixing arms to the inner hole which gives low er

flybar ratio.

Insert the aluminum Main Rotor Hub Pin and the Flap Dampers. (might need to apply silicone grease for easy installation). Push

the No.7 Feathering Spindle into the dampers and the rotor hub.Add No. 14 Flybar Control Rod. Slide both finished Main Rotor

Grip onto the feathering spindle and the secure with two M4x10 bolts and washers according to the drawing.Use two Allen

wrenches to tighten the two M4x10 bolts simultaneously.

Important Note:

The Raptor 90 3D kits come with non-linear flap damper for aggressive 3D flying.You may choose to experiment adding from

one up to three 0.4mm thick shim (No.10) washers between the washer (No.8) and bearing to further stiffen the main rotor flapping.

Stiffing the main rotor head will speed up the cyclic transient response, but may cause the helicopter fuselage to oscillate at arou nd

1600 RPM.This oscillation characteristic exists for all helicopters with hard 3D flap dampers.The inner dampers should be

replaced periodically if a lot of 3D flying has been done. When the dampers are worn, the main rotor blades canflap excessivel y

during some 3D maneuvers and risk touching the tail boom.

Add flexible silcone glue or ZAP

Goop glue around the outside

before inserting into the tail

boom from the front side.

Engine System

Use a high quality 90 size 2-stroke

model helicopter engine, such as the

Thunder Tiger TT PRO-90H, OS 91

SZ-H, YS 91 ST, Webra 91, or

equivalent. Please beware, some

engines may not fit because of their

shape and size. The Raptor 90 3D

kit comes with a cooling fan hub to fit

the TT PRO-90H, OS 91 SZ-H, Webra

91.

We recommend a high quality muffler

or tuned exhaust system designed to

fit on the left side of the model.

Rotor Blades

It is important to use main rotor blades

that are of high quality and suitable

for your flying style. If fiberglass or

carbon graphite blades are used, the

length should be between 680 and

710 mm. Blade weight should be

between 170 and 200 grams.

Starter System

To start the engine, it is necessary to

use an electric starter with a 6mm

shaft extension. The starter and the

6 mm extension are available from

Thunder Tiger, the part numbers are

No.2675 and No.3801.

Use a strong high torque 12 volt

electric starter which is designed for

models.

Add a small drop of Loctite.

Make sure it locks the pin.

Install BK0364 and BK0362 onto BK0365 Tail Gear Drive Shaft. Then insert the

two Pins and secure them with two M3x4 Set Screws. Add a tiny drop of Loctite

on the set screw thread before inserting them. Always use a very small amount

of Loctite liquid on the thread, otherwise it may be nearly impossible to remove

the set screws in the future for servicing. After installing the two M3x4 set screws

(No. 1), try to push on the 2x12 pins with a small Allen wrench to make sure the

set screws have locked the pins in place securely. Install the four ball bearings

and the hex shaped Frame Spacers according to the drawing. Before closing

the two halves of the Tail Boom Brackets, please check the gear mesh between

gears No. 4 and No. 5. If there exists too much freeplay, add some 5 mm i.d.

washers on top of gear No. 4. (The 5 mm i.d. washers are provided in BAG G).

Add a small drop of Loctite.

Make sure it locks the pin.

Attach the engine mount to the engine using four 4mm bolts and Loctite.

The cooling fan hub is threaded to fit the OS, TT or Webra only. Place the washer that came with your engine onto the engine

crankshaft first. Then screw the fan hub onto the engine. Add a tiny drop of Loctite on the engine nut. Do not use too much

Loctite. Tighten the engine nut using a socket head wrench while grabbing the fan with a towel. The nut should be tighten securely.

For 50-size or bigger engines, we do not recommend using a piston locking tool on the glow plug hole because that may damage

the engine. Attach the No. 8 Heavy Duty Clutch to the fan hub. Add a drop of Loctite on the threads of the M4x8 bolts. The

threads on the aluminum cooling fan hub are for the TT 70H, OS 61 SX, OS 61LX, OS 70H, TT 90H, OS 91 or Webra 91 engines.

If YS 61, 80 or 91 engines are used, the fan hub must be re-tapped by the modeler to M8x1mm thread size or purchase a optional

plastic fan hub with threads for the YS engine(PV0198YS) or the metal fan for the YS (PV0293YS).

Please complete subassemblies 1-5-1 through 1-5-5 first, then add them to the Main Frame. Fit the Pitch Control Frame

Subassembly. Attach the E Ring on the left side of the Metal Elevator Control Arm. Then fit the Elevator Control Lever to the

right side, insert the pin and fix it with a set screw. Secure the Pitch Control Frame with a M3*10 Socket Screw and a collar on

the left side. And attach the Elevator Push Pull Lever to the right side of the Pitch Control Frame as shown. Adjust the two bolts

so that the Pitch Control Frame can move freely without excessive play. Finally, add the two plastic Aileron Levers and the 66.5mm

elevator pushrod. Add the Washers (BK0088) to make sure that the Aileron Lever and the Metal Elevator Parallel Lever will not

touch each other during operation.
