it's inside the radio.
You're looking for the "CD8081" signal IC, on the main board of the transmitter... Yes it will say "CD8081" on it!

When you find the signal IC "CD8081" the PPM signal is on pin #11.

I will post pictures soon... sorry for the delay.

I would buy the FrSky DHT DIY kit, $30.00... Rx run about $25.00. All you need to do is solder three wires; one wire (yellow) to the "CD8081" signal IC, on pin #11. the other two wires are for power; run the Black(Ground) to your battery pack, run the Red(Hot) to the transmitter switch. Yo...

The kit I used is the: "FrSky DHT 8ch DIY 2.4 module"... Long winded name :lol: I bought it on ebay for around $30, with free shipping. Hobbyking also sells the kit, just look under "FrSky, Transmitter module" and you will find it. I will document the conversion, in this post, on...

I know this is an old thread, but it's worth another look. You CAN turn an old futaba magnum to 2.4, using the FrSky DHT DYI kit. The old magnums had either the "CD8081N" or "NE5044" signal IC. Both chips are almost identical 16 pin IC's. Pin 11 is the PPM(signal). Pin 16 is the ...
