There are several receivers you can get, in addition to the Futaba receives. I'm not a Futaba person, but can guide you a bit with others that will work. For instance, Berg makes a very nice small (physical size) receiver that is full range and seven channel. Their 7P. It is compatible with just about all 72 MHz transmitters. Check that out. It's a very solid receiver.
As for servos, well, just about any servo will work too. You can get some pretty good deals on standard servos from Futaba, Airtronics, Hitec, JR/Spektrum, that all meet the needs of your aircraft of choice.
The Airtronics basic servo is on sale for under $10.00.. there is a posting here somewhere that has that information.. or someone will give you an update of that servo. The servo is a 94102Z and works just fine.

for the Berg 7C receiver. Don't forget to buy a crystal with it if you decide to get this one. You have to specify what channel you want it for and pay the extra for the crystal.
