Default Removing duct fan blades

I'am new at this, can anyone tell me how to remove the blades on a duct fan, without removing the whole motor.

There should be a screw at the center of the blades. If you turn the screw out that should release the blades from the motor, leaving the rest of the setup intact.

Hope that helps.

If they are the stock motors/fans that came with the Tian Sheng C-17, when you remove the fan screw, you should see (partially) the end of the motor shaft. The shaft has a small flat which the fan blade unit mates into. It is a snug, force fit.....the blade unit should pull straight off. When reassembling, you must align the flat on the motor shaft with the mating recess in the blade hub.
