The last Challenger hack module did not show any pics of the innards…
The original Futaba “module” is plugged into the side of the PCB with a 5 pin “Molex” PCB plug and socket. I have used the plug to fit the hack module.
From the bottom the pins are:
1, PPM out, Yellow wire with diode.
2, +V, Red Wire.
3, Ground, Black Wire
4, Connect to 3.
5, Antenna connection. ( the real smart ones amongst you can use the antenna connection to connection on the main PCB to fit the co-ax for the 2.4 antenna)
The LED is quite bright, but you are looking at your aircraft, aren’t you?
