An interface to install JR type modules on Futaba /Hitec style radios. With this you can use for instance the last FrSky XJT module or a 433Mhz long range module designed for JR / Taranis / Turnigy radios. I tested this interface on a Hitec Aurora trasmitter with succes. It's only necessary to build an interface cable made from dupont cables in order to supply Vcc, ground and PPM signal.
Here is my personal add-on to two works from toemat and from dmyers7, I only added an interface block that connects the two modules and remixed Aurora module with longer strips in order to facilitate extraction.
This work is made of three parts, a dummy module for futaba/hitech bay, an interface block to connect futaba/hitech module to JR case bymeans of three M3 screws - so it's removable - and JR case itself. JR case shall be glued (epoxy) in final position on the interface block after check for interferences. I preferred to rotate 90° clockwise for clearance and module extraction, so my antenna lies horizontally.
