For the record, I looked at my GWS RD8SL receivers and they have the slots for the Futaba connectors on them.

I have a couple of R127DF receivers and even a PCM R138DP. I like Futaba receivers just fine, but not so well that I'm willing to pay $72.98 for a receiver and crystal.

One of the R127DFs came with my 7CAP, while the other came with an Easy Sport I bought. I bought a 7CHP radio system and sold the transmitter, so I got the R138DP w/ crystal, 1000Mah RX battery, four S3151 digital servos, switch, and servo extension all for about $113 net cost.

My attitude is basically that Futaba makes great receivers, and if you can pick one up without getting scalped, then by golly go ahead and get one! If your options are to pay regular price for a Futaba receiver and crystal or to get something else that is just as good for less, then you should probably save your money.

Considering Futaba pays you $3.00 to take a 4YF Transmitter w/ TX crystal, TX battery, frequency flag set, and wall charger instead of just buying a flight pack and receiver crystal without the transmitter, it just makes more sense to buy a whole radio system and part it out than to buy seperate Futaba radio components as you need them. I like Futaba transmitters, receivers, and servos but Futaba's pricing structure simply defies logic.
