In September 2016 I started experimenting a new 4" format using 1407-3600Kv motors with an extremely light set-up.
After weeks of bothering CMW to design a specific frame for this format, the SL4R came to life. Since the release of the SL4R, the new generation of 4" machines became a bit more popular than the old heavy 180 frames.
