INTRODUCTION

Thank you for purchasing the Durafly Tundra V3. After the incredible success of the Tundra V1 and V2, Durafly has decided to produce yet another version with even more improvements to bring this model bang up to date. The V3 is now a pure 4S set-up so it has power in abundance to make your flying even more fun than it was before (if that is at all possible!). Other changes/ improvements are daylight bright LEDs (so bright they are suitable for dawn to dusk flying), a reinforced nylon prop that is more efficient, and better balanced, a return to the classic EPO foam wheels which are lighter, and stronger, and hex-head bolts and screws throughout. The V3 is available in a "Classic" green color scheme, and also a new red and silver scheme Durafly has called the "Inspire". The reason being is that the original Tundra was "Inspired" by the "Highlander" full-size SuperStol experimental airplane.

So if you are looking for flying with no limits then you’ve found it with the Tundra V3. Whether it’s flying from rough bush fields, water, snow, or sand, FPV flying, aerobatics, glider towing, candy dropping, or just good old fashioned super STOL slow flying, then the Tundra V3 takes it all on with ease. Its lightweight yet rugged construction, powerful brushless set-up, and perfectly harmonized design give you an instant feeling of confidence on the sticks as quickly as it puts a smile on your face.

The Tundra V3 also includes the revolutionary Aerostar RVS (reverse function system) G2 ESC, this ESC offers instantaneous reversing, so there is now no need to stop the prop before reversing. This makes it perfect when using the Tundra V3 on the water as a floatplane, but it is also great fun in the air, and really good for short landings, just ensure the prop is on nice and tight!!

Simply put, the Tundra V3 is even more fun to fly than previous versions, and you will be flying even quicker as there is now even less assembly on the V3. With either the included floats, tow mounting point, and FPV canopy, or with the optional skis and candy dropper, the choice is yours regarding how you put your Tundra V3 to work.

ASSEMBLY (PNF)

Out of the box your Tundra comes with reinforced foam hinges. However, before you start the assembly, each hinge line must be flexed back and forth 5 to 6 times to reduce the tension and load on the servo. Do this to all the control surfaces before continuing. The aileron pushrods are factory installed, so you will need to use some pliers, or better still, ball-link pliers to pop the ball-link connector off the control horn before you do this.

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

the supplied M2.5x8mm hex 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) . Use secure the main gear and spring support wire in place with the plastic undercarriage straps (D).

the supplied M2.5x8mm hex bolts to

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.

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 plastic 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).

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 M2.3x8mm hex self-tapping screws and join the elevator with the single M2.3x8mm hex self-tapping screw (B). This installation is self aligning, but do double check to ensure equal aligment to the vertical stabilizer 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 the push rods until both surfaces are neutral.(B) Tighten firmly when done. For added security if you wish, the tail can also be glued in place.

As mentioned earlier in this manual, the aileron pushrods are already installed, but you will still need to attach the flap pushrods. Insert the flap push rod through the servo arm and secure in place with the plastic keeper (A). Now set the flap servo arm as far forwards as possible, then connect the ball-link to the flap horn and adjust so that the flap is in the fully up (B).

Notes: 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.

Attach each 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 hex bolts supplied (B)..

The final stage of assembly is to mount the Durafly 11.5”x5” nylon reinforced 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 should 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..

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

tape or hook & loop self adhesive tape in the location shown (A) under the rear fuselage access hatch. Ensure the Rx aerials are held away from the servos.

Congratulations, basic assembly of your Tundra V3 is now complete.

Please perform a final check on all screws, bolts and components,

ensuring all are secure and firmly in place.

Setting Up Your Model:

With your receiver installed and all servos plugged into their corresponding channels, connect the

1. 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.

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.

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

Optional Skis

The optional skis are a worth while addition to the Tundra for flying from both snow and soft sand. First remove the main wheels and slide the plastic sleeve over both axles (A). Then slide each ski onto the axle/sleeve (B) and once in position hook the tension spring around the back of the landing gear wire (C).

Note:

You may wish to add a collet to the axle to give the assembly additional security.

Model Flying Precautions

Select your fl and buildings and away from crowed areas. Avoid flying in areas with roads, electric/telephone poles/wires and water near by (unless using the floats) 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, and also risks damage to the model.

This model is 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.

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 manufacture s 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 screw/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.

Flying The Tundra :

The Durafly Tundra 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

at lower speeds and with an indulgent use of the flaps, the Tundra 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 rolling across the ground is just as exhilarating as rolling through

As mentioned in the introduction, the Tundra V3 is fitted with extremely bright LED's, this makes it

suitable for flying from dawn to dusk. This and all the other attributes makes the Tundra V3 one of

the most versatile RC planes on the market today.

Tundra Tips:

If flying from a hard surface (tarmac, asphalt) then remove the spring system from the

undercarriage to avoid 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 4S would be a more suitable LiPo to use rather than the heavier 2200mAh 4S when flying from water. This will keep the overall wing loading .

If you intend to perform STOL style landings often with your Tundra, 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 for prolonged periods of time. This will have an adverse effect on the foam surface of the model.

we know you’ll enjoy it immensely.
