Hobby knie with #11 blade

Installing the rigging will add to the appearanceand strength o your airplane, but you will not be

able to remove the wings without cutting the rigging.The rigging is required on your model. DO NOT

ly your model beore installing the rigging.

You may want to thread the rigging through

a needle to make it easier to pass the riggingthrough the holes, especially the tubes in

the uselage near the bottom wing.

Another option is to soak the last 4 inches(100mm) o the rigging line with thin CA to stien

it up so you can pass it through all the holes.

1. Cut the rigging thread in hal. You will need twopieces o thread to accomplish the rigging on theFokker DVII.

2. Insert the rigging thread into the lower orwardhole in the outer strut.

3. The rigging then is routed to the cabane strutand goes through the holes in the cabane that areto the ront o the aircrat.

4. Route the rigging down to the orward hole inthe outer strut.

5. Next, the rigging will go up and to the rear holein the outer strut as shown.


19/28


6. The rigging will now go through the rear tube inthe uselage. Note that the rigging in this step mustbe behind the rigging headed upward (Step 3).

7. Ater exiting the tube, route the rigging up andto the rear hole in the outer cabane strut as shown.

8. To complete the irst stage o rigging, tie therigging at the top o the strut as shown. Use low-tack tape to secure the tape on the underside o thebottom wing. The end taped will be secured oncethe rigging is ready to be tensioned.

9. The second stage o rigging is similar to the irst.Start by inserting the rigging thread through therear hole in the outer strut.

10. The rigging now heads to the cabane strut togo through the rear holes in the struts. This line willbe in ront o the current rigging lines.


20/28


11. The rigging now heads to the rear hole in theouter strut. Again, this line will be in ront o thecurrent rigging lines.

12. Route the rigging up and to the orward hole inthe outer strut.

13. The rigging now goes down and through theorward tube in the uselage. This line will be inront o all the other rigging lines.

14. Ater exiting the uselage, route the rigging upto the orward hole in the outer strut. Make sure

the rigging is in ront o all the previously installedrigging lines.

15. This completes the second stage o rigging. Uselow-tack tape to secure the tape on the undersideo the bottom wing. The end taped will be securedonce the rigging is ready to be tensioned.


21/28


16. Use the ollowing images to veriy the rigginginstallation. When tensioned, the lines will all runperectly straight and not cause others to be movedout o position.

17. Apply light tension on the rigging lines. Usea drop o oam-sae CA at each point the riggingpasses through the struts. Allow the CA to ully curebeore moving your model. Dont orget to tie theends that were taped to the bottom o the wing atthis time as well.

18. Use a small amount o white glue to glue the

rigging at the uselage. This will make it easier toremove the rigging lines i you need to remove the

wings rom your model.

19. Use scissors to trim any excess rigging rom themodel at this time.

20. Use hook and loop tape to mount the battery inthe uselage as shown.

Center of Gravity

An important part o preparing the aircrat or light isproperly balancing the model.

Caution: Do not inadvertently skip this step!

The recommended Center o Gravity (CG) location orthe Fokker DVII 250 Slow Flyer is 13/4 to 2 inches (44to 51mm) back rom the leading edge o the top wingas shown with the battery pack installed.

When balancing your model, support the plane uprightat the marks made on the wing with your ingers ora commercially available balancing stand. This is thecorrect balance point or your model.

Adjust the motor battery as necessary so the model islevel or slightly nose down. This is the correct balancepoint or your model. You should ind the CG to be

very close with the battery installed orward in thebattery area inside the cowling.

Ater the irst lights, the CG position can be adjustedor your personal preerence.

Control Throws

1. Turn on the transmitter and receiver o yourFokker DVII 250 Slow Flyer. Check the movemento the rudder using the transmitter. When the stickis moved right, the rudder should also move right.Reverse the direction o the servo at the transmitteri necessary.

2. Check the movement o the elevator with theradio system. Moving the elevator stick orward willmake the airplane elevator move up.

3. Use a ruler to adjust the throw o the elevatorand rudder. Adjust the position o the pushrod at thecontrol horn to achieve the ollowing measurements

when moving the sticks to their endpoints.

Elevator Low Rate

Up 3/8-inch (9mm)Down 3/8-inch (9mm)

Elevator High Rate

Up 1/2-inch (12.5mm)Down 1/2-inch (12.5mm)

Rudder Low Rate

Up 1-inch (25.5mm)

Down 1-inch (25.5mm)Rudder High Rate

Up 11/4-inch (31.5mm)Down 11/4-inch (31.5mm)

Measurements are taken at the inner orwidest point on the control surace.

These are general guidelines measured rom our ownlight tests. You can experiment with higher rates tomatch your preerred style o lying.

Travel Adjust, Sub-Trim and Dual Rates arenot listed and should be adjusted accordingto each individual model and preerence.

Preflight

Check Your Radio

Beore going to the ield, be sure that your batteriesare ully charged per the instructions included with

your radio. Charge both the transmitter and receiverpack or your airplane. Use the recommended chargersupplied with your particular radio system, ollowingthe instructions provided with the radio. In most cases,

the radio should be charged the night beore goingout lying.

Beore each lying session, be sure to range check yourradio. See your radio manual or the recommendedrange and instructions or your radio system. Eachradio manuacturer speciies dierent procedures ortheir radio systems. Next, start the motor. With themodel securely anchored, check the range again.The range test should not be signiicantly aected. Iit is, dont attempt to ly! Have your radio equipmentchecked out by the manuacturer.

Keep loose items that can get entangled inthe propeller away rom the prop. These

include loose clothing, or other objects suchas pencils and screwdrivers. Especially keep

your hands away rom the propeller.

Double-check that all controls (aileron, elevator, rudderand throttle) move in the correct direction.

Check the radio installation and make sure all thecontrol suraces are moving correctly (i.e., the correctdirection and with the recommended throws). Test runthe motor and make sure it transitions smoothly romo to ull throttle and back. Also ensure the engine isinstalled according to the manuacturers instructions,and it will operate consistently.

Check all the control horns, servo horns, andclevises to make sure they are secure and in goodcondition. Replace any items that would be consideredquestionable. Failure o any o these components inlight would mean the loss o your aircrat.

Flying Your Fokker DVII Slow Flyer

You will ind the Fokker DVII Slow Flyer to be a solid,honest-lying model.

Ensure your CG is set according to the manual andpower up the aircrat. Move your throttle trim upslowly until the motor just begins to spin. This will be

your light idle that will help to establish a longer glidepath and to make landings easier. Beore taxiing out

to the runway, double-check all controls are working inthe correct direction and unctioning properly. You willind the rudder very eective; on the ground, trackingis very predictable. Apply power smoothly and beginthe takeo roll. Correct with rudder as necessary andapply up elevator slowly until the model lits o .

You will ind lying the Fokker DVII Slow Flyer to bevery relaxing and easy. The model is not designedor high-speed light. Most light is accomplishedbelow hal throttle and will yield lights in excess o20 minutes with an 800mAh 2-cell battery with aPark 250 when outitted with the GWS 7 x 3.5 prop.

Landing the Fokker DVII Slow Flyer is as easy assetting up on inal approach, lowering the throttle toidle and gliding in to a sot touch-down.

You will ind the Fokker DVII 250 Slow Flyercapable o basic loops and stall turns. Flying these

maneuvers is easy and un with the Fokker DVII250 Slow Flyer. Ater your irst light you will want

to check your rigging to make sure none o the

locations that were glued with CA have loosened.Check these areas on a regular basis to ensure saeand reliable operation. We hope you enjoy theexperience o lying the Fokker DVII Slow Flyer.

Happy landings.

Range Test Your Radio

Beore each lying session, and especially with a newmodel, it is important to perorm a range check. Itis helpul to have another person available to assistduring the range check. I you are using a Spektrumtransmitter, please reer to your transmitters manual ordetailed instructions on the range check process.

1. With the model resting on the ground, stand 30paces (approximately 90 eet) away rom the model.

2. Face the model with the transmitter in yournormal lying position. Be sure the throttle is in theull down position and plug the light battery intothe speed control.

3. As you move the controls, watch to be sure theairplanes motor and controls operate smoothly.

You should have total control o the model at 30paces (90 eet).

4. I control issues exist, call the Horizon SupportTeam at 1 877 504 0233 or go to horizonhobby.comto ind a local Spektrum distributor in yourcountry or service i you are using a Spektrumradio system.
