Hshaped structure does not affect the flying experience at all. On the contrary, compared with the Xshaped structure, the arm is shorter and lighter. At the same time, the arm strength is higher. The Hshaped layout has more installation space in the middle section of the cabin and a lower center of gravity, making the flight more stable. The installation size of the FPV lens is 19mm wide Flight control installation positions with two hole spacings of 30.5*30.5 and 20*20 are reserved at the front and rear of the cabin. Suitable for the installation of a variety of flight control equipment. Fixed motor mounting hole spacing: 16*16/16*19/19*19mm are compatible. The corners of the entire machine are chamfered to create a fine workmanship and reasonable structure. Of course, there are also customized thickened aluminum tubes to ensure the strength of the frame. Package Included: 1x Frame Kit 1x Set of 3D Printed Parts
