Hi Dave
your combination will work with a T18MZ Transmitter but not a T18SZ.
For example:
Using our telemetry converters for Futaba / Jetcat you can have JetCat Display assigned to Slot # 2-15 and PowerBox System Teleconverter to Slot # 16-31.

On that web page you will also find a Picture for your required Setup.
By the way you have still slot number 1 free for a IAS Speed Sensor.
This is the best Setup for Jetpilots with Futaba.
