How to Choose a Propeller for an FPV Motor
Diameter alone is not enough for an automatic recommendation. StartX requires an explicitly confirmed propeller model with complete geometry.
Motor / KV → Battery S → ESC current / S → Prop diameter / pitch / blades → Battery
Which propeller fields are checked?
The selected motor variant must reference the exact propeller model, and the catalog specification must include matching diameter, pitch and blade count.
Why is a diameter range insufficient?
Different pitch and blade count can materially change motor load. StartX therefore does not turn a broad diameter range into a product recommendation.
Confirmed catalog examples
These are not universal recommendations: every relationship below comes from the current structured StartX database.
