One rule in the FPV industry is that drones will continue to get faster, stronger, and in turn - more power hungry. While some pilots may scoff at 70A ESCs for their current builds, many pilots are pushing high cell lipos along with high KV motors, which can be highly demanding on your electronics, especially ESCs.
With the advent of brushless motors getting smaller and smaller, it's now time to upgrade your micro quad's old school brushed motors to miniature brushless motors. Brushless micro FPV quads are an absolute blast to fly. They have more torque, more thrust and recover quicker than any brushed quad.
As brushless motors go, they don't get much smaller than the DYS BE1102. The motor is suited to micro class FPV quads: 70-100mm frame size.
