I just got a coupler of new receivers and the label has been updated the FHSS has been removed.
The actual receiver board is very low profile except for the connector and the large aluminium electrolytic capacitor.
With a smaller tantalum capacitor and the connector modified I have managed to get a receiver + antweight speed controller smaller than the original receiver.
Module 9x25.5x42 mm and 10.2gms including 120 mm leads where as the oringinal receiver is 11.5x20x50 and 6.6 gms

The servo connector has been changed in the final cased version as it takes up less room and the fourth pin enables the use of full battery voltage on weapon controllers or servo.
