This is the first racing frame from RotoWorks. The split arm design with braces makes it a very durable quad designed to eat gate polls without breaking.
It is designed for 20x20 FC and ESC stacks with M3 holes. It is recommended to use a nano-sized RX (e.g. FrSky R-XSR or Crossfire Nano) and nano-sized VTX (e.g. TBS Nano).
The 3D printed parts are not included - they are necessary to complete the quad. The parts are camera mount, battery pad, and fin (for turtle mode). The antenna mount is designed for Foxeer Lollypop antennas. All 3D files can be downloaded from Thingiverse: https://www.thingiverse.com/RotoWorks/designs
