So whilst building a sub 250g 5 inch I thought I ought to build a sub250g 4 inch to compaire it to, I looked at a number of frames and it came down to the CMW superlight 4r and the Kinetic Aerial Air-Ro, both very similar but the Air-Ro is half the price for no particular reason and has a 3mm baseplate instead of 2.5,
It was also my first raceflight1 build and initially I had a lot of trouble with yaw glitching, a big thanks to Denovich for helping me sort it out.
AUW with a tattu 650mah 4s is 235g, switching the arrow to a micro when it arrives, shortening the standoffs and looking to bring it down to sub250g with an 850mah
