UMX STOL Trainer with Spektrum technology. Trainer model with large bush wheels. Powerful 1810-2000KV brushless motor. Lightweight and robust EPO material with a takeoff weight of only 157 g. 4-channel control: motor speed, ailerons, elevator, and rudder. BNF-Basic version with Spektrum dual protocol DSMX & SLT receiver. Equipped with exclusive SAFE technology. SAFE stands for Sensor Assisted Flight Envelope and is an electronic flight stabilization system that caters to the varying needs of beginners, intermediates, and professional pilots. The multi-axis sensors, combined with unique software, enable the model to determine its position relative to the horizon. The SAFE technology can thus control and correct the aircraft's orientation as necessary. The desired flight mode limitations can be switched at any time using the remote control. Each mode offers greater ranges of motion, allowing the pilot to safely improve and develop their flying skills. BNF - Bind and Fly. The advantage of Bind and Fly models is that they come pre-built and wired. Since a receiver is already integrated, these models only need to be bound to a compatible remote control. A brushless motor is an electric motor without brushes, which offers higher efficiency, less wear, and lower weight compared to brushed motors. Skill level: beginner. No special prior knowledge in model building is required for this product. The necessary materials for completion and commissioning are usually included in the delivery.
