Simple is beautiful. Without any landing gear to deal with, the Arrows Hobby 50mm Viper is lightweight and streamlined-
perfect for those with a tight flying field or budget!
To minimize drag, increase flight time and guarantee the Viper’s precision flight characteristics, Arrows Hobby designed an
innovative single-piece wing structure and horizontal stabilizer. The lightweight airframe and exceptional aerodynamics give
the Arrows Hobby 50mm Viper excellent low speed handling and flight time- uncharacteristic for small EDF jets of its size.
Power comes courtesy of a 50mm 11 blade fan unit, 2627- 4500KV brushless motor and a high performance 30A ESC (with
3A BEC)- giving unparalleled speed and sound.
How do you get pinnacle performance on a small budget? Let Arrows Hobby work its magic with the 50mm Viper!
