As you can read in my other articles on my quad project, I chose to skimp on the chassis and purchase the Hobbyking knockoff version of the DJI Flamewheel. After the first crash I broke one of the arms. I was able to bandaid the arm to keep me flying but I ordered a pair of authentic DJI replacement arms. I wanted to show the significant difference in the products. I’ll be purchasing a complete Flamewheel chassis to swap over. No money saved this time!
