I can think of three ways to use 3rd party PPM based modules with an Evo and firmware v3.xx.
1. Use the trainer port which still provides PPM.
2. Fit a small custom board that accepts the Evo serial data on the module port and in turn generates PPM for a module with a slight delay. There is a thread on here where this is done.
3. Fit a small custom board that answers the Evo power up inquiry via the serial interface on the module port pretending to be a later type 35MHz RF module. The Evo will then generate PPM on the module port even with v3.xx as that is how the module works!
