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 Heather Stokes

This package comes without documentation and the components don't have part numbers, so I can't find a datasheet or figure out how to assemble everything. I emailed the seller 4 days ago but he didn't reply. The radios aren't 3DR as advertised - I believe they're made by YRRC, and there doesn't seem to be an owner's manual or datasheet anywhere online. I can't connect them properly. Pixhawk also throws an ahrs error. Update: Apparently my PX4 is defective. I will be returning this kit. Update 2: The sellers don't speak English and don't even know what they are selling. My second PX4 had intermittent servo outputs. I returned it and bought a Pixhawk from Mrobotics (which cost a little more). The Pixhawk was originally designed and built by 3DR, but production has since ceased to focus on software. Recommendation: If you want to try a fake and it works, that's great, you saved a lot of money (+$100) and helped maintain Chinese hegemony (it wasn't fair, I'm black like everyone else) . Revain has a good return policy. So if it doesn't work, you can keep rolling until you get a good one. When you get tired of it, buy a real one.
