0802 motors between 19,000KV and 25,000KV are a great choice for a 1S whoops. For 1.2 inch (31mm) props choose a 3 blade prop. For 1.6 inch (40mm) props choose a 2 blade prop. (see examples)
This 19,000KV motor is best suited to a 1.2 Inch (31mm) 3 blade prop. But a 1.6 inch (40mm) 2 blade prop would also be okay.
