This is my Turnigy 9X transmitter, witch I'm very glad for and this is the changes I've made to it.
  • First mod was the mod for flashing the firmware to ER9x opensource firmware. It opens a lot of posibilities and is easy to do.
  • Got the Trustfire 2500 mA batteries instead of the 8 x AA batteries. Runs for hours now
  • Back light for the the display. A must have. I choose the white one witch gives the clearest display.
  • Made a extra modification to the back light to make it programmable via ER9x firmware.
  • Trainer resistor fix. Made a solution to allow connecting of a additional transmitter or simulator via the jack plug on the rear side.
  • Switched the transmitter to FrSky to get a better receiver with diversity and failsafe (FS).
  • Switched the FrSky 2 dBi antenna to a 4.5 dBi antenna for a little better range.
  • Turned the carrying handle the other way for better storage as it was taking to much room.

Upcoming project

I have a SkyWalker 1900 witch I use for FPV flight. I use Eagle Tree System OSD with GPS and airspeed/altimeter sensors.

I have for a long time wanted to have my pitot tube mounted on the wing instead of right next to my FPV camera. So I finally came up with this solution.

The senson is mounted on the wing with tubing to the pitot tube.
The wires from the sensor is long enough to connect to the altitude sensor (EagleTree System).
A small fearing around the sensor for "protection". I might add some more and paint it black
Mounted on the right wing so the the tubing don't cross.
I used mesh and heat shrink to secure the tubing....Continue Reading
