I recently bought an Eachine Tyro99 kit but I didn't really like the frame it came with. He was clumsy and clumsy. I was looking for something cleaner and lighter. When I saw this frame I decided to give it a try instead of the Tyro99 frame. Installation was very easy. Inside there is plenty of room for a 4-in-1 speed controller, flight controller and video transmitter. The camera is well protected and easy to set up. The frame is made of good carbon and doesn't flex. Installation is easy even without instructions. I did a test flight and everything seems to be working fine. I am very happy with my purchase.
