Arrows Hobby’ s sincere work, the 1200mm Trekker!
Arrows Hobby has always hoped that the developed model can not only meet the needs of novice players to get started, but also
meet the needs of old players to explore more gameplay. Therefore, the research and development concept it upholds has never
changed, that is, " higher stability, better handling, more possibilities". Trekker is a work based on the above standards.
Quick-release and quick-install structure, especially the buckle-designed horizontal stabilizer and front landing gear, enables the
airplane fly in the sky in five minutes upon unpacking-with a full-charged battery. It is remarkable that the fuselage adopts a two-sec-
tion structure, which is convenient for carrying, storing, and replacement of accessories.
Built with ultralight EPO foam, the large wing area, high-winged airframe configuration gives the Trekker low wing-loading and
extraordinary amounts of lift, even at slow speeds. The use of the tricycle-geared layout helps to have a better rolling directionality.
The main landing gear is made of durable aluminum plates, with large spans on both sides and flat arcs, which can effectively
absorb the impact of heavy landing. Furthermore, optional floats add to the all-terrain fun of the Trekker.
The power system adopts a brushless configuration, which can burst out enough power for completing stunts such as inverted flight,
roll, somersault, and low-altitude flight.
Trekker is a typical 4-channel aircraft: throttle, elevator, rudder, aileron. For novice players, it's clear at a glance, and for old players,
it’ s greatness in simplicity
For pilots who are looking for an aircraft that has gentle trainer characteristics, plenty of power and graceful lines- the 1200mm Trek-
ker is all of that, and more.
• Power configuration: 3136-KV1200 motor, 20A ESC, 11.1V
1300mAh 25C battery (RTF configuration provides battery).

• Simple, lightweight and easy to carry design.
• Buckle-designed horizontal stabilizer and front landing gear.
