This repository contains the electronics and software for a flight controller. This controller is designed to run a coaxial helicopter using brushed DC motors. The board contains an rf transciever chip for wireless communication with a remote. I had to learn alot for this project, as there were several things I had no experience with such as the radio transceiver circuitry. In the end, it turned out well and was very fun to make. # PCBWay The PCB was fabricated and assembled by PCBWay (link to www.pcbway.com). I’m impressed with how it turned out, and I’ve written a short review below based on my experience working with them. #### PCB Quality The finished PCB looks and feels excellent. The boards appear durable and well-made, with solid electrical connectivity throughout. Silkscreen print is sharp and clear, and the overall finish gives off a professional feel. #### Assembly Quality Assembly was just as good. All components were placed with precision, aligned nicely with their pads, and the soldering was clean — no excess, no bridges, and everything stayed neatly within the boundaries. #### Communication & Support Working with PCBWay was a smooth experience. They were professional and quick to respond to any questions I had. One thing I really appreciated was their communication before making any key decisions. For example: - They double-checked with me before sourcing alternative components. - When a part was unavailable, they suggested alternatives instead of just swapping it. - After assembly, the quality control team contacted me about the orientation of a particular component, just to be sure, as the markings were slightly ambiguous. #### Pricing & Turnaround Pricing was fair, especially considering the quality and the support included. Quoting and sourcing components was made easy — PCBWay handled that for me, which saved a lot of time. Once everything was confirmed, shipping was fast and the boards arrived well-packed. Overall, I'm happy with the result and wouldn’t hesitate to use PCBWay again in future projects. If you’re looking for a PCB manufacturer that’s reliable, responsive, and produces high-quality results — they’re worth checking out. # Electronics **Motor drivers**
