2.4 GHz to 433 MHz PPM relay

Copied from another FPV Pilot we call "The Pianist

Very reliable PPM relay system. I use a Turnigy BEC to supply 5v to the receiver and 12v straight from a 3S pack to the DragonLink tx. I can put my 433 antenna gs anywhere in the launch site and do not have to worry where to point my tx antenna. I also used a PPM encoder to translate PWM from my Turnigy RX to PPM and fed straight to my DragonLink tx.
