Finding where the PPM stream is, cutting its PCB path and injecting the PPM of my own "big boy" transmitter.
I hate thumb controllers, Id much rather enjoy "pinching" my own familiar pult transmitter sticks.
I don't think there is any PPM anywhere in the original Hubsan Tx. it directly speaks SPI as far as I know.
