The frame is gep-tsx5, Named Viper.
GEP-TSX5 is made of 3K Carbon Fiber Quadcopter Frame plates and the Grand 12.9 YFS screw. The Stretch-X made it more adapted to the Racing. Our design teams decide to use 5mm(thickness) x 9mm(width) Arm to overcome wind resistance effectively. The motor seat is redesigned to a large extent to protect the motor. The camera seat works for most brands, Such as Runcam swift /swift2, Foxeer HS1190 and so on. The camera 20 to 60 degress. But I’d like to introduce the GoPro. 35-58 degress. Applies to most scenarios. Such as Racing and Freestyle.
