DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION ASSEMBLY: Step 1: U/C Assembly and Fitting. 1.Identify the parts shown above for the U/C assembly. 2.Use a box spanner or similar to undo the lock nuts on the axle. 3.Slide a wheel on to one of the axles, ensure the long spigot slides on first as shown. 4.Re-fit the lock nut using your spanner. 5.Tighten the nut so that there is no slop, but the wheel spins freely on the axle. 6.Repeat the process for the other wheel.
7.Identify the pack of four 3x10mm machine screws. 8.Using the 3x10mm screws, attach the U/C assembly to the bottom of the fuselage. Please note the direction of the cut out in the center. Step 2: Attachment of the Horizontal Stabilizer and Tailwheel. 1.Identify the parts for the horizontal stabilizer. 2 x horizontal stabilizer halves, 1 x 210x3mm carbon rod, 3 x 2.6x8mm self tapping screws with molded on washers. 2.Slide the 210x3mm carbon rod through the hole in the rear of the fuselage. 3.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION 5.Using two of the 2.3x8mm self tapping screws, secure the two stabilizer halves to the rear of the fuselage. 6.Using the third 2.3x8mm self tapping screw, secure the joint between the two elevator halves. 7.Clip the ballink on the pushrod onto the ball that is attached to the control horn. If the elevator requires adjustment to ensure it is neutral, this will be covered later in the set-up part of the manual. 8.
3.Next stage is to attach the wing struts to the fuselage using the two M2x10mm screws and lock nuts. 4.Ensure that you attach the wing struts so that the large dished end faces the underneath of the wing. 5.Also the struts are handed with one marked with an "L". This strut goes on the left hand side looking from the rear. 6.Attach the struts using the M2x10mm bolts using the supplied hex key and a spanner or thin nosed pliers. 7.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Step 4: Wing Assembly. 1.For this step you need the wing and the two plastic wing protectors. If you are using the bandon wing system then you must use both protectors. If using the bolt-on system then you do not have to use them if you do not want to. 2.If you have elected to use the band-on method, then use a good quality glue such as UHU Por to glue the protectors to the wing. 3.Plastic protectors glued into their correct positions. 4.
7.When using the band-on method it is best to use 4 bands for safety. If you only received 3 bands with your Prime Tundra then any good quality rubber bands can be used. If bolting the wing on then use the supplied M2.5x16mm machine screws.. 8.When assembling the wing to fly, push the end of the strut over the metal spigot sticking out of the wing and retain with the supplied "R" clip. Slide the "R" clips on from the leading edge side of the fixing as shown.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION 3. Before switching your transmitter on, ensure that the throttle stick is fully down and throttle trim is in the middle position as shown on the T6A. Also, if you have programmed a throttle disarming switch, ensure it is in the disarm position, the gyro switch can be in any position. Now switch the transmitter on, and ensure your battery indicator is in the green. 5.
7.The wing can now be re-attached to the fuselage using either the bands or the bolts. Before you actually fit the wing back on you need to connect the two "Y" leads that are connected to the wing servos. Connect these "Y" leads which should be labeled "Flap" and "Aileron" to the corresponding extension leads that are plugged into the receiver. Ensure these connectors are fully mated so that they cannot come apart, tuck the wires away safely, then attach the wings. 8.
DURAFLY PRIME TUNDRA 1200MM READY TO FLY VERSION Aileron Elevator Rudder 10. Your Prime Tundra now needs to be set up so that all control surfaces are set at neutral. With the system switched on and the gyro initialized the control surfaces should all be in their neutral position. Ensure when you do this that the gyro is off, and all the trimmers on your transmitter are also in their neutral position. If for any reason a control surface is not at neutral, you will need `to do one of the following. 11.
15.Now we need to check that the controls are working in the correct direction, see below. Roll Left: Move the aileron stick to the left, the left aileron should go up. Roll Right: Move the aileron stick to the right, the right aileron should go up. Pitch Up: Move the elevator stick down, the elevator should go up. Pitch Down: Move the elevator stick up, the elevator should go down. Yaw Left: Move the rudder stick left, the rudder should move to the left.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION 16. You will now need to set the control throws, these should be as follows. The lower figure is with the D/R (Dual Rates) switched on, and the higher figure with the rates switched off. If you are not sure how to set the Dual Rates, please consult your transmitter manual. Do these checks with the gyro in the off position.
6. Checking the gyro settings. 1. You now need to check that the gyro is functioning correctly. 2. Move the gyro switch down into the "Training Mode", this is the switch in the fully down position. Now smartly roll the wings left and right, you should then see the ailerons moving in the opposite direction to the rolling moment. Then smartly pitch the nose of the plane up and down, you should then see the elevator servo moving the elevator in the opposite direction of the pitching.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Step 7: Fitting the Propeller. Now you have finished setting up the radio, gyro, and servos, you can install the propeller onto the motor shaft. 1.Please ensure you fit the propeller the correct way around. The picture above shows the front of the propeller, so this of course should face forwards, in the direction of flight. 2.Remove the prop nut from the motor shaft,slide the propeller onto the shaft and replace the nut.
Step 8: Battery Installation and Setting CG. 5 -60mm 1. The recommended center of gravity (CG) for the Prime Tundra should be approximately 55-60mm from the leading edge of the wing. This should be easily achieved if you use a 1300~1400mAh 3S LiPo battery weighing between 110~125g. Ensure it is up against the foam ledge in the battery compartment as shown in the picture below. Once the position of the battery is determine, secure it in place with the supplied hook and loop tape.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION 9: Flying the Prime Tundra. Once all the above has been done, you should be ready to fly the Prime Tundra for the first time, then we highly recommend that you enlist the help of an experienced RC pilot by joining a local model flying club. Here you should find a wealth of experience and knowledge from fellow members to help you in getting into the air within a frame work and environment that is both safe and organised.
6. When you have completed a satisfactory range test, return to the model and the flying area. Face the model into the wind and stand a few paces behind it, do a final control check. Disarm the motor, ensure the gyro switch is in training mode, and the rate switch is in low rates, you may also need to hold in some up elevator if the grass is a bit long. When ready, smoothly open the throttle up to full power, slowly ease off the up elevator if you have some in as the model accelerates.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Please remember, if when you are flying and you get into a muddle, the gyro is there to help you. If this happens, just let go of the control sticks, reduce the throttle, and let the model sort itself out. Once the model is flying straight and level again, ease the throttle back to around 50% and carefully bring it back to the flying area if it has drifted away. 10. The next thing we need to think about before the battery gets too low is the landing.
Also at this point remember that the elevator controls the speed of the model. If you are flying too slowly then lower the nose using the elevator, if you are flying too fast then raise the nose slightly, again using the elevator. When you are between 1-2ft (50cm) above the ground, close the throttle completely and the model will land itself.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Using Flaps. When you feel you are ready, the time will come when you want to use the flaps. Using flaps is great fun and a big feature of the Tundra series of models. Flaps help shorten the take-off and landing, enable the model to fly slower, and will help you make steeper approaches to land. As with the dual rates, you need to build up slowly to using the flaps.
Then initiate a go-round by smoothly opening the throttle, select half flap, and climb away into wind. Do this 2 or 3 times until you feel really comfortable using full flaps on the approach. Now start your circuit at the normal height and go for a full flap landing, the Prime Tundra really does this well, especially with the gyro in training mode. As mentioned before, the approach will be steeper, a bit slower, and the landing run very much shorter.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Flying the Inside Loop. The inside loop is the easiest of all the aerobatic maneuvers to fly. Start by flying straight and level in to wind, no lower say than 75-100ft. Apply full power and, at point A in the picture above, pull back on the elevator stick to start a climb - not too much, be gentle but precise. Keep the power on, your Prime Tundra will go into a vertical climb.
Gyro Off Mode. Before you go any further with aerobatics, we highly recommend that you learn to fly the PT1200 with the gyro in the "Gyro Off" mode. This way you will not be relying on electronics and technology to help you fly, but purely your own skills. Once you are proficient in flying with the gyro off, there are quite a few more maneuvers the Prime Tundra can perform, but we will not go into those in this manual.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION Fitting the Optional Candy Dropper. A.Position the foam support over the mounting holes on the underside of the fuselage. B.Feed the Y lead for the Candy Dropper through the center hole and connect to a spare channel in your Rx. C.Secure the Candy Dropper using the supplied bolts. D.The finished Candy Dropper installation. Please Note: This optional part has been designed for dropping candy only, or other very light in weight items.
Fitting the Optional Floats. 1.Remove the wheeled landing gear and replace the screws. Clip into the slot the front float support legs. 2.Unscrew the strut retaining clips at the rear, slot in the rear float support legs, and replace the retaining clips. 3.Slot the float cross braces into the inside holes of the float front and rear mounting points. 4.With the floats assembly on a flat surface, lower the Prime Tundra onto the floats. 5.
DURAFLY PRIME TUNDRA 1200MM PLUG AND FLY VERSION 7.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 supplied water rudder. Both tail wheel and water rudder mount in exactly the same way.
Flying your Prime Tundra from water Just as flying from land, select your flying area careful, avoid small areas of water with trees, etc, choose a nice size lake if you can. Please also remember that you will need to either obtain permission from the owner of the area, or use an area that is already designated for model flying. Due to the water rudder taxiing the Prime Tundra is very easy.
