Assembly (PNF)

1. Out of the box your Tundra comes with reinforced foam hinges. However before assembly can begin, each hinge line must be flexed back and forth 5-6 times to reduce tension and load on the servo. Do this for all control surfaces before continuing.

2A. To mount the undercarriage to the fuselage, start by inserting and securing the two rear braces

with supplied M2.5x8mm screws (A). Now insert the main gear wire into the fuselage slot and slide the plastic brace keepers over the rear braces (B) to bring these two parts together. Insert the spring support wire between the main gear wire (C) . Using supplied M2.5x8mm screws secure the main gear and spring support wire in place with the plastic undercarriage straps (D).

Notes:

- Ensure the main gear rakes forward at stage B.

- Note left (L) and right (R) marked plastic straps and install accordingly during stage D.

M2.5x8mm

Page 7

2B. Hook the supplied coil springs through the center ring of the spring support wire and the wire

cross braces through the ring of the metal brace keepers (E) to complete the sprung cross bracing assembly (F). Now slide the main wheels onto the axle and secure in place with the plastic grip nut (G). Assembly of the undercarriage is now complete (H).

E. F.

G. H.

3. Insert the tail wheel assembly into the plastic slot on the bottom of the rudder and secure with two M3x6mm screws (A). The same method is used when mounting the water rudder (B).

A. B.

M3x6mm

4. Insert one half of the carbon tail spar into one of the horizontal tail pieces before sliding this half

into the tail slot on the fuselage. Now install the remaining tail piece (A). Secure both halves in place with the supplied M2.3x6mm screws and the elevator join with the single M2x8mm screw (B). This installation is self aligning, but do double check to ensure equal aligment to the vertical tail and wing.

Page 8

5. Using a pair of pliers (ball link pliers preferably) connect the elevator push rod to the elevator horn

(A). To ensure both the elevator and rudder are neutral (with the servos centered) loosen the grub screw of the piano wire fastener and slide push rods until both surfaces are neutral if required (B). Tighten firmly when done. For added security, the tail can be glued in place too.

2x8mm

6. With the aileron control horns at 90 degrees to the wing surface (neutral) insert the aileron push

rod and secure in place with plastic keepers (A). Connect the ball link to the aileron control horn as shown (B). Repeat this same process for the flaps, the exception being the flap servo horn must be positioned as far forwards as possible. This will give a flap neutral position with the push rod connected (C).

7. Insert the wing spar into the fuselage at the wing root (A) ensuring it is centered. Slide one wing

half at a time onto the spar, pushing each panel firming into place on the fuselage (A) and secure each panel with the provided M2.5x8mm bolts (B). Take care to ensure the wing servo PCB is not damaged when connecting the wing to the fuselage.

Note: For convenience clear tape alone can be used to secure the wing to the fuselage by

running the tape along the entire span of the wing join. However this is not recommended if you intend to fly the Tundra aggressively.

8. Attach every wing strut to their respective sides (A), both struts are marked ‘L’ and ‘R’ to note left and right hand sides if looking forward from the cockpit. Secure firmly in place using the M2.5x8mm screws supplied (B).

A.A. B.

9. The final stage of assembly is to mount the Durafly 12”x6” carbon propeller using the prop nut as shown (A). However at this stage it is HIGHLY recommended that all set-up and final checks of the model be done before finally installing the prop firmly in place.

Note: The propeller should be balanced out of the box, however it is recommended a final

balance check be carried out before attaching to the model. A well balanced prop will greatly increase all round performance and efficiency of the model in flight.

Page 10

10. Install your choice of 6-channel receiver (OrangeRx R620X shown) using double sided foam

tape or Velcro in the location shown (A) under the rear fuselage access hatch. Ensure Rx aerials are held away from the servos.

Congratulations, basic assembly of your Tundra V2 is now complete.

Please perform a final check on all screws, bolts and

components, ensuring all are secure

and firmly in place.

Page 11

Setting Up Your Model:

1. With your receiver installed and all servos plugged into their corresponding channels, connect the flight battery to the ESC to power up the electronics. With the model now armed, ensure all servos are centered and all control surfaces are level. If not, adjust by turning the control clevises by hand accordingly until the control surfaces are level as shown.

Note: For safety reasons, it is advised that this is done with the prop removed from the model.

Aileron Elevator Rudder

2. Check all control surfaces are moving in the correct direction with the correct stick input (see below).

3. The Tundra V2 handles very well in flight and that’s not down to good design alone, but a good

pre-flight set-up too. Before you fly your Tundra please follow the recommended settings below for optimum handling and performance.

Control throws:

8-14mm

8-12mm

Elevator

Rudder

50-60mm

Aileron

10-20mm

*Elevator: ‘low rates’ 8mm, ‘high rates’ 14mm in either direction from neutral. *Rudder: ‘low rates’ 8mm, ‘high rates’ 12mm in either direction from neutral.

*Ailerons: ‘low rates’ 10mm, ‘high rates’ 20mm in either direction from neutral.

4. Flaps on the Tundra will need to be set for 3 stages (up/no flap, mid flap and full down flap). Either via your radio or mechanically by turning the clevises on the flap control rod (or via both in most cases), set mid flap to approximately 45 degrees and full flaps to approximately 90 degrees to the wing. In the ‘up/no flap’ position ensure the flaps close fully without straining the servos and are both level with the trailing edge of the neutral ailerons. Also check that both flaps deploy equally at every stage.

5. The recommended center of the gravity (CG) for the Tundra V2 is approximately 50-60mm from the leading edge of the wing. Your Tundra V2 should balance within this range with anything from a 1800mAh - 2200mAh 3S LiPo installed as far forwards as possible in the battery area. Your battery can be secured in the battery bay area with the velcro provided.

With assembly and set-up now complete, your Durafly Tundra

should now be ready for flight. However we recommend your read

and follow the advice given in the following pages of

this manual before flying your model.

Page 14

Tundra V2 Options:

Your Tundra V2 comes with several features available to you during the assembly. Floats , FPV canopy and tow mounting point are all included in the box. Use of a Candy dropper is an optional extra and is not included. All however are covered in these following pages.

Floats

1. With each float placed on a level surface and parallel to one other, add the front and rear cross bracing struts by inserting each end into the inner most hole of the float mounting plate (A). Now insert the ends of the front and rear fuselage mounting struts into the center holes (B). With all float struts installed as shown, secure in place using the M2x8mm screws (C).

Page 15

2. With the floats now fully assembled and landing gear completely removed, insert the front fuselage mounting strut into the main gear housing and onto the rear mounting plate (A). Secure the rear with supplied M2x8 screws (B) and the front using the original main gear mounting plate and screws.

A. B.

3. Although not always required, a water rudder does help with steering in less than calm water conditions. Simply remove the tail wheel and replace with the water rudder (A). Both tail wheel and water rudder mount in exactly the same way.

Page 16

FPV Canopy

To assemble the plywood FPV canopy you’ll need some CA and no more than 10 minutes to glue it all together. All parts are laser cut and following the below exploded diagram, the assembly should be self-explanatory. Note to allow some time for the glue to cure on the magnet so the bond is as strong as possible. Also be mindful not to let any glue get to the exposed surface of the magnet.

With the canopy now assembled you are free to install your FPV equipment as you see fit. However you may wish to follow the simple example shown below.

Page 17

Tow line mounting point

The built-in tow line hard mounting point gives the Tundra a solid point close to the CG to attach a tow line for gliders etc. The below cutaway shows how the tow line should be inserted and attached to the main spar through the tow line slot.

Note: The model you are towing will need a tow release system of some kind. The hard point on the Tundra is for attaching tow line only.

Optional Candy Dropper

Mounting the optional Candy Dropper is quick and easy. Position the foam filler over the mounting holes on the underside of the fuselage (A). Feed the Y-lead supplied with the dropper through the center hole and connect to a spare channel on your Rx (B). Secure the dropper using the bolts that come with it to the fuselage (C).

Model Flying Precautions

● Select your flight area carefully. Always choose an open space that is unobstructed from trees

and buildings and away from crowed areas. Avoid flying in areas with roads, electric/telephone poles/wires and water near by or within close proximity to full size air traffic.

● Do not fly this model in poor weather. High winds, low visibility, inclement temperatures, rain and

storms are to be avoided.

● Never attempt to catch this model whilst in flight. Even a slow moving model can cause harm to

yourself and others

● This model is recommended for children no younger than 14 year old. All children, no matter

what age, should always be supervised by a capable and responsible adult when operating this model.

● Always unplug your model battery when not in use. Never leave the battery installed in the

model.

● Remember to keep clear of the propeller at all times when your flight battery is connected.

● Before flying, always turn on your transmitter first then plug your flight battery into the model.

and risks damage to the model.

● After flying, always unplug your flight battery first then turn off your radio transmitter.

● Exercise caution when charging your batteries and follow in full your battery manufacturers

safety guideline when doing so.

Pre-flight Checks

1. Always range check your model before any flight (especially when flying a new model for the first

time). Follow your radio manufacturers guidelines for performing this check.

2. Check all screws, bolts and mounting points are firmly secured, including control horns

and clevises.

3. Only fly with fully charged batteries (both in your radio and model). Failure to do so could result

in loss of control, damage to the model and/or persons/property around you. Check your batteries are fully charged.

4. With the model powered up (transmitter on first, then receiver/model) check that all surfaces are

free from damage/obstructions, moving freely and in the correct directions with the stick input.

5. Inspect the model and prop for any damage that may have occurred during transit and listen for

any unusual sounds from the electronics when powered up. If in doubt, do not fly.

6. With the model held securely and the prop free of obstructions, increase the throttle just slightly

to confirm the rotation of the prop is correct. The model should want to pull straight forward with throttle.

7. If this is your first flight with the model double check the C/G is at the correct position. If not adjust

battery position inside model accordingly.

8. If you are an inexperienced model pilot seek the help and assistance of an experienced pilot to

perform these final checks and to test flying the model for you.

Flying The Tundra V2

The Durafly Tundra V2 is both an easy and versatile aircraft to fly and has no special considerations

when it comes to flying but do make sure you’ve followed the set-up guidelines and

recommendations in this manual thoroughly for the best flying experience.

Thanks to the powerful motor and prop combination you can be off the ground (or water) within just

a matter of meters if you are looking for a nice long rolling take-offs, however where’s the fun in that!

Once you have your model trimmed, the real fun starts with the zero rollout, full flap take offs, just be

ready to hold in some down! In the air the Tundra V2 is super stable at any speeds too, full throttle

sport flying allows you to explore the full aerobatic potential, whereas at lower speeds and with an

indulgent use of the flaps, the Tundra V2 really comes into its own with almost full STOL type flying

characteristics, flying slow has never been so much fun. On the ground too, with the very authentic

bush style tires and functional sprung undercarriage, the ground never looked so inviting. With the

Tundra V2 rolling across the ground is just as exhilarating as rolling through the air.

Off water the only real consideration is getting of the surface of the water itself. This is greatly aided

by the use of half flaps on all take off runs as they will help lift the Tundra V2 up off the surface of the

water. For towing, just remember to always keep the line tight and to stay below the model being

towed.

Page 20

Tundra V2 Tips:

●

If flying from a hard surface (tarmac, asphalt, concrete etc) it is recommended that you remove the spring system from the undercarriage to void excessive bouncing on landings.

●

When flying with floats of water, it is advised to always use at least half flaps on takeoff. Semi deployed flaps will greatly increase the Tundra's ability to lift off the water surface.

●

When landing on water, always land with a good amount of forward momentum to help achieve the smoothest water landings possible.

●

Use of water rudder should only be needed when flying from rough water. Generally the standard rudder alone is sufficient for flying off calmer waters.

●

Due to the added weight of the floats, a 1800mAh 3S would be a more suitable LiPo to use rather than the heavier 2200mAh 3S used when flying from water. This will keep the overall wing loading from going up.

●

If you intend to perform STOL style landings often with your Tundra V2, it is suggested you use the optional tail brace upgrade supplied with most models. This will greatly improve the strength and rigidity of the tail which will be of great benefit with the higher forces at play with landing STOL.

●

For optimum flight performance/model longevity, it is highly recommended that you always fly with a balanced prop. The supplied prop should be balanced, but it’s always good to check first.

●

Keep all leads within the fuselage area as tidy as possible. Tidy wires look better, allow for easier access to all internal components, better battery installation, increased airflow around electronics and a reduction in potential electronic signal interference (noise).

●

Do not leave your model in direct sunlight or in a hot car for prolonged periods of time. This will have an adverse effect on the foam surface of the model.

Thank you again for purchasing the Durafly Tundra,

we know you’ll enjoy it immensely.

Don’t forget, spare parts are available for this model,
