Sleek, light and quick, the Arrows Hobby Viper is a 50mm EDF jet that makes a strong case for small electric jets. A 50mm 11-blade fan driven by a 2627 4500KV brushless motor on a 3S LiPo gives it real speed and a proper jet note, while the rigid one-piece wing and tailplane keep drag low and handling precise, so it flies smooth, flowing aerobatics and still slows down well for the landing.

There is no undercarriage: the Viper is hand-launched (it has moulded grab handles under the fuselage) and belly-lands on grass or another soft surface. That keeps it light, simple and cheap to run, and small enough to carry to the field in one piece. The switchable Vector 3-mode stabilisation system is pre-installed: Stability (auto-levelling), Dynamic (wind damping, pilot keeps full control) and Direct (gyro off), so it copes well in a breeze and gives a first-time jet pilot a safety net that can be switched off once it is no longer needed.

Motor, fan, ESC, servos and Vector unit are all factory installed and the airframe screws and glues together in about 30 minutes. Add a 6-channel radio and a 3S 1300–2200mAh LiPo and it is ready to fly.
