Durafly PRIME TUNDRA Instruction Manual Download Page 3

Thank you for purchasing the Prime Tundra, it is yet another addition to the extremely popular Tundra 

series of STOL (Short Take Off and Landing) airplanes from Durafly, but this one is aimed primarily, 

but not exclusively at the novice. It is also the perfect STOL trainer for those that want to get into this 

style of flying as it inherits the excellent STOL flying characteristics of the Tundra lineage including the 

large Tundra style flaps, it's a lot of fun for the seasoned Tundra fans to! It is the most stable Tundra 

to date even without a gyro, but coupled with the pre-installed ORX 3-axis gyro it is taken to another 

level. The Prime Tundra is the perfect choice for a very first RC airplane due to its rugged and simple 

lightweight construction, fast and easy assembly with no gluing, but mainly because of its superb, and 

very benign handling characteristics, making it the most stable and sedate of the Tundra family.

The PT1200 is supplied with the exact same tried and tested big wheels from the original Tundra 

which makes them perfect for every type of surface, be it a runway or a mountain track. This makes 

the Prime Tundra a very versatile aircraft, and that versatility extends to the wing mounting system 

too. The PT1200 is supplied with a 'Bolt or Band' wing mounting option. We recommend using the 

elastic band on wings if you are a novice and the bolt on system for those more experienced fliers. 

Another great feature is that it has the option for floats making it perfect as your first choice of 

floatplane. This version of the Prime Tundra is supplied RTF (Ready To Fly), this means it comes

complete with everything you need except for a flight battery, flight battery charger, and some "AA" 

batteries. It is supplied with an easy to use Turnigy T-6A 6 channel transmitter and receiver, 3-Axis 

ORX gyro, motor, ESC, and 6 digital servos, all these items are preinstalled at the factory.

So if you are looking at starting RC model flying then look no further than the Prime Tundra, it is the 

perfect choice. But also, the Prime Tundra is a fantastic sports aerobatic/ STOL plane with a flight 

envelope that will appeal to the most discerning pilot. Learning to fly has just become a lot more fun 

for novices and their instructors with the Prime Tundra.
