This product is used for four-axis UAV, upper and outer shell. It is made of 3K twill shaped cloth, high-gloss transparent rubber coat matrix solidified by vacuum induction process. It is lighter and stronger than plastic parts under the same size condition. So far, many UAV manufacturers are using composite materials as the preferred material for the UAV shell. Some people say that the UAV shielded signals and could not receive GPS signals. This problem can be avoided in design. The whole part of the fiberglass cloth can be laid where the GPS signals are placed in the manufacturing process. With carbon fibers, the signal can be received and the strength can be improved!
