Wufnu,

About the RFFS -

The R and E are the rudder (or aileron) connectors, and the E is for the elevator. The coils just plug in to the connectors, if you want to reverse the throw, reverse the two plugs. The plugs on the end of the baoard are the power (outside two plugs - positive is marked with red), and the inner pair are from the built-in ESC and go to the motor. The last plug (in the middle of the board) is for the antenna.

Actuators -

The magnets 'float' in the coils through one of two means:
1) you use a 'remote' actuator assembly that has a mount that slips inside the coil with the magnets mounted to a pivoting axle. There are output arms attached to that so you have a place to hook up a push rod, or
2) the coil is built into the ttail surface with the coil centered over the hinge line. The movable part of the surface has a wire the magnets attach to, and this is bent so that the magnets are centered in the coil. This way, the movement of the tail allows the magnet to stay centered.

Actuators are wound with very fine enamled wire (#40 to #44), and yes, you can wind your own. I would suggest that you buy some to see how they operate and then try some of your own.

LiPolys -

The leads to the battery can be soldered to wires that you hook into the RX. You can also built a battery pack with contacts inside so the battery can be slid into place and make contact.

Here are three photos of actuators. The first show a couple of RFFS installations showing the radio hook up, a slide-in battery pack, and remote actuator set up. The third shows a surface mounted actuator.

The E-zone column 'Inside Story' (http://rcgroups.com/links/index.php?t=sub_pages&cat=199) has lots of info on actuators and small radio related topics, and RCGroups' indoor and micro forum (http://www.rcgroups.com/forums/forum...?s=&forumid=85) has several sticky threads at the top with tons of references and sources for this specialized area of modeling.
