This week I walk through modifying my Flysky 9X with an LCD back Light, A programmer so I can flash open source code onto it and also upgrade the RF module to a FR-Sky RF module which gets me better range, a failsafe option if I fly out of range and telemetry data back.
The radio is available for $59 and the upgrades are about $40 total. So for $100 you get a radio that is worth $300 - $400.
Plus, I flash the new code so you can see how much better the new code is than what came on the radio. I now have much more flexibility with the switches, the interface makes sense and so much more.
