RE: Hitec and 2.4
The problem is the 5 pins are on opposite side of the plug. The 2.4 Futaba module does not work because of the antenna orientation.
The XPS modules worked until they reworked the antenna and now their newest Futaba/Hitec design is only good for Futaba...BUT...they are going to continue selling the original design that fits Hitec Eclipses, Prisms, Optic 6's.

These work well for me with 2 Eclipses.
