Just after the last motor announcement, seems racerstar will also update its 0603 lineup with their BR0603B: https://www.banggood.com/Racerstar-Racing-Edition-0603-BR0603B-16000KV-14000KV-1-2S-Brushless-Motor-For-RC-Drone-Frame-Kit-p-1277111.html
This motor is proposed actually in 12000/14000/16000 and soon in a 22000Kv version. All of them are 1-2S compatible and weights only 1.58g !!!!. Probably the futur 22000Kv will be the best choice with 26g of pull !!! That’s great really, almost the same performance of a 0703 motors but 23% lighter. We can dream of super lightweight brushless FPV racer pretty soon.
