I ordered this motor, ESC and prop set from Aerocraft, and after 27 days I finally received the package. Is this the proper way to attach the prop to the prop saver that was built into the motor? I have to double up the band to make the prop stay put, is it ok to double the band like this? How safe is it to fly a plane with the prop just banded on? As you can see in photo 4 I can still push the prop down on one side, is this proper or did I do something wrong?

Also, in the last photo, can I simply solder the wires of the motor and ESC together without connectors?
