Used a few times, in excellent condition. It was working normally until removed. Instruction manual included. The following is the manufacturer's description: Quest When it comes to scale flight, you want that unique slow-rotation blade sound, right? With the standard Kv1250 motor for fast flying, we were concerned about ESC heat at low RPM, so we've prepared the Kv740. ● Reduces the load on the LiPo battery and ESC, enabling high-efficiency flight, and allows for over 10 minutes of flight with a scale body attached. *Scale flight when using a 6S-5000mAh battery. ● MAX is set to 1500 RPM for low RPM flight. *With standard pulley 24T ● Reduces shock at startup. ● If requested, we can also change the MOTOR to E6S-550SPORTS, etc. Ideal for those who are afraid of the main rotor spinning at high speed even though they only hover. *Around 10 minutes after the start, the main rotor rotation will be 1300 RPM or less and the helicopter will shake, so please end the flight then, and there will still be plenty of battery remaining, reducing battery damage. Please purchase if you understand that this is a used item stored at home (as usual, please understand no returns, no exchanges, no cancellations).
