ZMR 250 antenna & XT60 extension

ZMR 250 quadcopter extension for the top plate for mounting the VTX antenna and XT60 battery connector. Includes recessed hex on bottom of antenna hole to keep the coaxial connector from rotating when you screw on the antenna.

Version 2 changes:
Added fillet near bolt holes for additional strength.
Enlarged recess for antenna hex. This was too small in version 1.
