The largest motors with a stator diameter of 29 mm and above – for example 3110, 3115, 3220, 3314, 4114, 4214, 4220, 4320, 5010, 5215 and 5315 – for large FPV drones and heavy-lift platforms with propellers from 8" to 16" and larger. Sizes 3110 and 3115 are typical for 8–10" builds, 3220 and 3314 for 10–13", and 41XX to 53XX motors for 13–18" propellers and high-payload builds.
They have low KV, approximately 340–1,250 KV, and require adequately rated ESCs and power supplies, typically 6S to 12S.
