Question: Red Washers

haven't seen it myself, but from the description I might guess they are intended as the washer to be placed above the prop before screwing down the retainer? note me know if I guess correctly. Otherwise, try to post ID/OD measurements for more accuracy.

They have four holes that almost look like the screw pattern for the motor mounts?
They are around an Inch OD.

Hi they are supplied with most F kits these are spacers which are used on 330 and 450 and can be used on 550 it's extra protection on the screws not hitting on the motor. I checked with quad copters.co.uk when I got mine not needed but he advised to use anyway.
