Review on 🚁 Pixhawk PX4 PIX 2.4.8 Flight Controller NEO-M8N GPS with 3DR 915Mhz Radio Wireless Telemetry Set OSD Module PPM Module I2C Splitter Expand Module Power Module for FPV Quadcopter Multirotor by Krystal Jones

First you need to know what you are getting. As far as I can tell, this is the equivalent of the Pixhawk 1, a proven flight controller. If you want something that only the Pixhawk 4 can offer, you'll have to spend a lot more. Everything worked fine for me with one exception mentioned below. The telemetry radio does not work by simply plugging it in, you must set it up in the mission planner first. I was able to easily update the firmware to the latest version available for the Pixhawk 1. I feel like I got the best possible deal for the money I was looking to spend and now my drone is in the air. That's why I bought this; it's a great package. Also, I can get a GPS block in my house in the basement, so I'm glad I went with the GPS that came with this kit (other packages have a much cheaper GPS block). I had an issue with BEC but after speaking to the seller they will take care of it. Right now I'm using another BEC that I already have.
