ZMR QAV Eachine Racer 250 Antenna holder for Redcon CM621 receiver

Edit 5/5/16 Added configuration that uses 2.5 mm straws to support antenna. Some brands of cotton swabs sold in the U.S.A. use a yellow tube holding the swabs. Cut to the right length, insert the antenna, and then the tube into the frame and you are ready to go.
Add drop of non-permanent glue as required.

This is a receiver/antenna holder for the Redcon CM621 DSM2 receiver sold at Banggood.com and others.
