The thrust-to-weight ratio of the bionic machine is about 0.8, and the maximum allowable climbing angle of 20-30 degrees. The fuselage servo, drive board, and receiver must be checked before powering on Bionic Butterfly. Bionic butterfly introduction: The design concept of the aircraft: the wing ribs and proportions are improved with reference to the design of real butterflies, and the wings are made of nylon silk fabric and carbon fiber materials according to the deformation of the wings The specific thrust realizes the definition of flight on the basis of low frequency, low speed and bionics, and forms throttle and liter according to the angle of the wings descending and directional control, extreme lightweight flight can achieve vertical climbing. Bionic butterfly parameters: Flight weight: about 59g Wingspan: about 75cm Fuselage: about 50cm Maximum load capacity:25g Environmental flight requirements: indoor or outdoor calm wind (wind has a great influence, indoor is recommended) Applicable scenarios: Personal flights, events, performances, visits, training, weddings, large-scale exhibitions.etc
