Hi Chellie, the 2409-7t motor is quite low KV.

You probably could use in on a smaller ducted fan like the 70mmEDF but you will need 4S lipo for performance.

I have modified the motor so that it can fit into hoa ye 89mm EDF.
Runs around 36amps on 3S lipo. It spins the 89mm EDF at around 24,000 to 28000rpm.


Cheers
