Essentials for ImpulseRC ApexDC

I have borrowed designs and remixed a few for ApexDC needs
Print without support. I have included support blocks that can easily removed with prying hand. Ensure Nano RX tray is standing uprise.

- Borrowed GPS mount from iFlight and remixed for ApexDC, this will fit iFlight GPS+Compass
- Print two spacers to keep space between Antenna Mount and GPS Mount
- Nano RX Mount, fits onto back of camera bracket then put standoff to secure them. Nano RX Mount has a clearance for access to bind button thru camera bracket
- Antenna mount is remixed with 6-sided HEX behind - no more turning while you tighten antenna
