If you truly want to DIY FPV quadcopter, you’d better start from a mini one like FPV 250. Measured 250mm in width and 80mm in height, this quadcopter is built from high quality and ultra durable polyamide nylon, forming into high-rigid frame perfect for PFV racing or obstacle course flying at your local field. Hereinafter we will take a closer look at the mini quadcopter frame.
First and foremost, FPV 250 utilizes gold plating technology chemically plated a certain thickness of gold on the PCB surface. And the surface added with electronic instruments is harder to oxidized and easier to soldered. Meanwhile, the frame provides double-side PCB, which results in stronger electric current flowing ability than single-side one. And it comes with recommended pan and tilt kit and all hardware for mounting motors and battery.
For instance, the front platform is designed to handle up to 2servo pan and tilt camera setup as well as rear platform, supporting video transmitter in order to keep all nice and balanced. In addition, FPV 250 possesses a center bay including a top crash cage for protection, which is large enough for most popular flight controllers. There are four integrated strap slots on the bottom to securely hold the battery in place for high G maneuvering.
Moreover, FPV 250 motor mount can handle motors from1506 to 2208. The vented arms greatly enhance cooling function for 7~12A ESCs. After testing different configurations and coming up with the optimal setup, the special kit was proved to be perfectly compatible with Multistar 1704 motors swinging 5x3x3 props. To round out the power system, high capacity LiPo batteries are very needed.
Last but not least, FPV 250 utilizes PA66 material, which is 8 times stronger than ABS material. The high-accurate equipment brass nut possesses remarkable toughness and resistance, quite different from easy-to-rust iron nut plated copper. From allover sides, the mini FPV uadcopter frame features better mechanical property, higher strength, fatigue resistance as well as smarter appearance.
