Smaller Etronix RX?

[Cardnim]

Wired up my SX3 and the reciever I have is just too big.
Ideally, I would like one of those postage stamp sized ones measuring about 1" x 1".

I have the Etronix PULSE 2.4Ghz 3-channel system and was wondering if any other 2.4Ghz receiver would be compatible but would be smaller than what I have.

N.B. I dont have the blue receiver (i.e. the FHSS) one, its the older DSSS that I have.

Heres what I have:

So would there be another smaller receiver out there that would do the same job and work with my transmitter?
Thanks guys.
