If you haven’t yet purchased a Turnigy 9x, you might want to instead consider the Taranis X7 which has even more features plus telemetry.
But if you already have a Turnigy 9x or got one on the cheap, here are a few things you should do to it right away as they’re all free or very inexpensive and will make your 9x experience much better.
1. Flash the firmware
2. Reverse the +/- buttons
Cut the +/- buttons from their holder and swap their locations. This will make perfect sense if you’re switching to upgraded firmware as they use the more intuitive plus (+) on the right and minus (-) on the left layout.
3. Add backlit screen
Add a backlit screen. They come in several colors, so get one to suit your liking.
4. Get a dedicated transmitter battery
Swap out the 8AA battery for a dedicated transmitter battery, it will last much longer and will be much easier to charge. Keep your 8AA battery holder and some spare AA batteries around for emergencies.
5. Relocate the module antenna
Relocate the antenna to the included module so you can actually remove the module and add a different one.
6. Trim the module pin stand-off
Cut off module-pin stand-off so you can fit other modules properly, like the Multiprotocol iRangeX module.
7. Rewire the trainer switch
Rewire the trainer switch so the “slave” is active when you pull the switch, not the other way around.
