Reviewer: Multirotor Builder from Pennsylvania United States
I bought 6 of these for a F550 Hexacopter. They are very similar in size to a 2212 brushless. The price can't be beat, they work great, but are a little fast spinning. I used them with 10x4.5 props and 20amp esc's. These motors got the esc's very hot and forced 2 of the 6 esc's into over heat shut down, all within less then a 2 minute test flight. The motors themself didn't get very warm. Now I have to buy a set of 6 30a esc's. I would recommend for multirotor use, but be sure to get at least 30 amp esc's.
Use the C22489 prop adapters, the C22490 adapters will force the motor to be mounted upside down, no good.
