Reverse Engineering a FlySky TX
I was once into hobby RC airplane stuff – unfortunately don’t have the time to fly these days. (Check my first flight here ) Got myself a cheap 6 channel FM transmitter on eBay back in the day, not that 2.4 GHz rubbish, one with a huge antenna, you know. It was a much cheaper option then. Not of very high quality, but capable of doing many cool stuff and it is highly configurable. It is possible to change throttle curves, do mixing etc. Configuration process involves connecting it via an “apparently” serial connector to its USB dongle (which is then a serial to USB converter) and a computer. Install an old school t6config program (still not an idea where I get it) on a Windows PC and you’re good to go. The serial connection is also used for controlling RC simulations although with a lot of effort. You need to intercept serial stick commands with a software tool (I remember using ppjoy) and map them to real joystick inputs, which the TX is not very helpful a...
