I took the LCD out of an old DVD player and mounted it to my Dx9 TX.
It was fairly easy to mod because the LCD driver accepts an analog video input.
All I had to do next was to add a 5.8ghz video transmitter module.
Some metals brackets and we're all set.
Well, almost. Now I have to cover up the back so the circuit boards aren't exposed.
The monitor and Vrx are powered from the TX 2200 mah lipo and activated with a switch installed on the back.
