/diy/ - Do It Yourself

The Mr. Steele motors are actually really good for freestyle but their design is a bit old. They are the best you can find to compare to the f40 pro ii

Naked bottom motors are better because sometimes if you crash with the old type the bottom of the motor rubs the bell. The newer naked bottom design is engineered to remove this failure point.

Also the C clips are going out of favor for using a screw to hold the bell on. And some grooves on the top of the motor helps the prop from slipping.

You can find motors that are more efficient than the Tmotor f40 pro ii but they will make much less thrust.
