I just got in a FrSky DJT module for my Turnigy 9x transmitter. But when I tried to install it, it didn't fit. I thought I had gotten a defective unit until I searched the usual forums. I found someone that had an identical issue and modified the DJT module. Then I found a thread on the Hobby King forum that said that the same issue existed with other brands of modules and the falut was with the Turnigy 9x.
It seems that the plastic at the bottom of the connector pins is too tall. So here is how I remedied the situation.
Here's a quick overview of the mod with a numbered picture for reference.
1) Remove the module and locate the pins in the bay.
2) Remove the four screws holding the PCB onto the back cover.
3) Slide the PCB away from the back cover so the pins come free of the base. You can just let the PCB hang while cutting the base down.
4) I used a dremel with cutting wheel to trim the height of the base.
5) Slide the pins back through the holes and test the fit of the module. Remove more material if necessary. When it fits, secure the PCB to the back cover with the four screws and reassemble the radio. Clean up any residue with a blade or screw driver.
This mod should make the Turnigy 9x compatible with any JR style module.
