Hi,
I have one E-Fly 100 C Tx, which i want to convert it to 2.4 Ghz  with Assan Hack(72 Mhz is not working, range problem). can some tell me where i can get the PWM signal from the PCB of Tx. Please refer to the Picture Below:

if you have access to pc scope then may be you can trace the PPM signal but from the pictures its hard to tell unless some one has already done it

Suppose i arrange the Scope from some wher, where should i trace the PPM signal, on the Rf board or on the main controller board....??

i was talking about free ware PC scope which will convert our sound card to scope (mic input)

after you have this setup, then probe the main board and i would start at the RF pins on the main board

In the picture No1 ,on the left hand side there are two pots used to set the side bands when the PPM signal modulates the ocilator signal produced by the crystal and associated components.So the PPM signa must be in on of the wires in the left hand side connector.Send a larger view of this portion of the back side of the rf card.

will upload a high resolution pick of back of RF card in a day or two.
