This is the 3d printable case for my Lockdown Radio Control. The Gerber files for the PCB (receiver too) are on GitHub with all the source code. It's a 16 channel system with a huge number of powerful features. It costs about £140.00 in components to build, and anyone can make one. A commercial system would cost far more and be MUCH less good too. This system does FHSS at 50 Hz, (2.40 - 2.48 GHz). The frame rate to model is 200 Hz. Servo resolution is 12 BITS, (or 11 BITS via SBUS). It has all imagainable features plus some you might not have imagined. Very easy to setup too using a capacitive 5" touch screen from Nextion.
