The UAV Lab(RD-4) RD-4 Undergoing dramatic rebuild
Published: Sat Apr 14 2012
So today, I disassembled RD-4. After the big crash I decided to rebuild it as a quad with 12 inch props. I shortened each arm from 347mm to 180mm. this will significantly reduce arm breakage risk and still allow for a wide range of prop sizes. [PHOTOS TO BE ADDED HERE]
