WING

TAIL

1. Locate the aileron servo well at the bottom wing. Use hobby knife to cut an “X” then tack down the covering with heat iron.

2. Secure the aileron servo in place and exited the wire at the wing root.

4.CA the four hinges on aileron. Make sure the hinges are centered.

5. Next attach the aileron to the main wing, apply CA on both side so the glue will seep into the trailing edge.

7. Secure the control horn with CA or epoxy, make sure the control horn is oriented to the pushrod. Snap Z-bend end of pushrod to the control horn and insert the other end to the EZ connector which should be installed on the servo horn with M2 washer and nuts.

8. Locate the fin the stab slots, carefully cut away the covering.

10. Remove the stab and fin, cut away the covering inside the lines you drew. Be careful not to cut into the wood as it may hurt the strength of the stab.

11. Attach the elevator torque rod first then install the stab in place. Center the stab and make sure the wing and stab is parallel, the fin is perpendicular to the stab. Glue the stab and fin in place with CA or epoxy.

3. Remove the aileron then center all hinges in place.

6. With servo horn and pushrod installed to decide the control horn hole. Next drill 5/32”(4mm) hole at the mark you decided. Make sure drill the hole perpendicular to the control surface.

9. Temporally install the vertical fin and stab. Make mark on stab and fin along the fuselage.

12. Same way as you install the hinge on aileron, secure the CA hinges on the elevators as shown.

TAIL

13. Apply epoxy in the elevator torque rod holes then attach the elevator onto the stab. Make sure it moves free after cured.

16. Trial fit the rudder in place, make sure it works fine then apply epoxy at the rudder torque rod hole and slot then attach the rudder on the fin. Wipe away the excess epoxy and make sure rudder works freely after cured.

19. Install the elevator servo as shown at the left side of fuselage. Remember connect the extension wire at least 12”.

MOTOR

22. Same way to install the rudder control horn in place as shown.

14. Install the tail gear and wheel in place with two

2.3 x8mm wood screws and wheel collar.

17. Same way to locate the rudder and elevator servo well. Cut an “X” at the servo well.

23. Secure the rudder servo at the right side of fuselage with 12” extension wire installed. Adjust the pushrod when servo and rudder are both in neutral position.

20. Same way as the installation of aileron control horn. Install the elevator control horn in place as shown.

24. Locate the brushless motor, cross mount, adaptor, prop nut and mounting screws if user buys the kit with motor.

15. Locate the rudder, glue the CA hinges as shown. Next use hobby knife to cut a slot so tail gear torque rod can accommodate to leading edge of rudder. This is to make hinge line gap as small as possible.

18. Heat treatment the servo well.

21. Snap on the pushrod first then attach the servo horn with EZ connector installed. Adjust the pushrod with elevator and servo are both in neutral position.

25. Install the motor on the fire wall with cross mount and adaptor installed.

RADIO

COWL

26. Install the carbon landing gear in place with M3x10 socket screws, M3 washers and M3 locknuts.

27. Drill 3mm hole for wheel axle, then install the wheel pant and wheel with socket screw M3x21mm, M3 locknut and washer. Adjust the wheel paint then secure the wheel pant with 2.3x8mm wood screw. Make sure the wheel rotates freely after installation.

29. Secure the battery with the tie belt as shown in the fuselage.

30. Correctly connect all servo wires to the receiver then secure receiver with nylon-tie band in place as shown.

32. Thread the antenna through the fuselage and exit at this opening. Tape the antenna properly at the bottom fuselage.

33. Same way to locate the middle bottom fuselage where is an opening for air outlet. Tack down the covering as shown.

35. Install the Canopy assembly in place. It should be secured perfectly with the super magnet.

36. Trail fit the cowling in place, make sure the prop adaptor is out of the cowling. Secure the cowling with four 2.3x8mm wood screws.

28. Trial fit and main wing in place, then install wing joiner. Locate the Nylon retaining screw then screw in the wing in place as photo shown in next step.

31. Locate the tail opening at the bottom fuselage. Cut a line in the middle then tack down the covering.

34. Locate the canopy & its frame, trial fit the frame in place. Make sure to leave about 3/32” (2.4mm) at twp sides. Note the front of frame should even with the canopy. The rear canopy should contact the turtle deck smoothly after gluing the frame.

37. Secure the propeller properly with prop nut. Now you finish the assembly please well adjust the control throw and CG before you go to fly.

CONTROL THROWS

BALANCE

Control Throws

The following control throw of 3D YAK EP is merely a starting point for your radio setup and can be tailored to fit your flying style. For all three models the aileron and elevator of the same throws but rudder are different as shown below.

Aileron-Low Rate

Elevator/Low Rate

Rudder /Low Rate Rudder/High Rate

1” (25mm)

1-3/4” (45mm)

Aileron-High Rate

Elevator/High Rate

3” (75mm)

1-3/8” (35mm)

3” (75mm)

LONGITUDE BALANCE

C.G. Must be set on thrust line

C.G. is too low C.G. is correct

As 3D planes do a lot of hovering so it is very important to do longitude balance to make hovering much more stable. Try to create a small hole after the motor and on the thrust line. Get music wire or string then thread the wire through the hole. Make sure that model hangs perfectly vertical as illustration. If not then try to adjust the location of battery, receiver or ESC to get good longitude balance.

BALANCE

It is important to balance the plane to get correct C.G. before you fly. Balance Point as indicated in each diagram.

3-1/4” (90mm)

Congratulations

Your done, may you have many successful flights filled with fun and lots of 3D maneuvers. Thank you for purchasing this plane from Thunder Tiger and we look forward to providing you with other great R/C products in the near future.

Exponetial

To make your 3D flight successful, the most important is to set up your radio properly and fine-tune the exponential. We would suggest that could show the exponential graph as the illustration. Normally this computerized radio has dual rates or even triple rates. Once you fly it fine with low rate in normal flight. Next you will have to set up 3D rate.

We suggest the 3D-rate setting is same as low rate setting around 1/3 of the total stick travel in the beginning. If you look at the graph , the middle section of 1/3 travel are most likely the same at low rate and 3D high rate .Beyond this middle section the 3D rate setting is far higher than the low rate.

SIMULATOR

A good tool to practice 3D easier is to fly simulator. One may say simulator is not realistic but this is not true. There are some simulators available in the market and its scenery and performance are just like a real thing .For example, Aerofly Pro Deluxe USB version from ikarus or Real Flight G3 from Greatplanes are all good simulators you can choose from . Simulator is a must buy tool if you seriously want to fly 3D aerobatics. There is no genius or born 3D pilot, remember that practice makes perfect. 30 minutes a day on a simulator can help you do hovering, torque roll easily as well as other aerobatics. If you would like to be a good 3D pilot, flying everyday is necessary. The reaction to control the airplane will be more nature. As there is no time to think when you do 3D aerobatics.

Simulator practice might be perfect yet suggest to do some actual flying as the supplemental so it will not go too far from the real thing as there are many things that you can not learn in screen.

FLYING

Even though you set up the airplane , it needs to be setup and fine-tuned in the air. Always start on low rates when launch the airplane or take off of the ground. Once you fine trim the airplane in the air then tune the exponential setting, you will be able to fly it all the time on the 3D rates. Once you got confidence to do hovering or do 3D aerobatics, we suggest you fly it near you. The closer the airplane, the better you fly it near you. The closer the airplane, the better you can control the plane as you can see it very clear even if it has a slight movement. The other advantage is the lower or closer to ground, the less potential energy. It is useful for a dead battery or ESC cut off suddenly.
