New FrSKY 2.4 Hack module in Aristo Craft Hitec Challenger 720
Anyone know the PPM signal out location on the Aristo Craft Hitec Challenger 720 Transmitter. I'd like to know the best place to tap for power, and for the PPM. If you have an idea, or photo....please let me know. I will post some pictures of the circuit board of the transmitter so maybe you no where to tap for power so my module will work. Frank from Massachusetts (Just a note) right now I have three wires soldered red, black, which is + & - and a white wire PPM signal but nothing is working, I just need the right ones to put connection.

Wow, that's an old unit...

I have the schematic for that unit and although it is marked up to show that the pin identifications are wrong, I have a sheet which shows the pin output as follows:

A = Antenna
B = Ground
C = Meter
D = Positive voltage
E = Modulation

Now, as to if it will drive a FrSky module is up to you to determine. I have no information on the voltage compatibility, Modulation +/- compatibility, or circuit load between the two units.

Use this data at your own risk.
