Check out-- Spadtothebone.com-- all kinds of how to`s, I use zip ties to hold most every thing on, that way the zips will break( in an crash or not so perfect landing) and your equipment won`t, believe me I`ve done proved it MANY times!!

Pics of GNAT building in Minnesota.... we set the CG at 3 3/4 inch. These are Futaba standard servos - either 3003 or 3004 depending on what is on hand. They "press fit" into the channel and are held in with nylon pull ties. The push rods for the ailerons are 2 X 56 rods, but the push rod for the elevator has to be heavier - 4 X 40 used here. On the underside you see where we are using fiberglass rods, the longer one above the channel, the shorter one below. For combat some are adding rods to the leading edge. The leading edge rods are not glued in, just place them before you fold the wing and compression will hold them for you. Hey.. Good Luck DickB

The standard Futaba 3004 and 3003 servos are .80 inch wide. The channel we are using here in the US is .75 inch wide. But, with a good push the servos slide in and are held really tight - which is nice. The nylon pull ties then cinch them down extra secure.
A couple of GNATS have been build with smaller servos and then the rail was crimped or pinch against them. As to the battery and receiver we have been putting the battery in the gap created underneath when the wing is folded over. Receiver can be mounted on the top of the wing, or if a Hitec Slimline receiver is used it can go beneath. The Slimline Hitec has the plugs coming out the back and it just slides into the wing gap similar to the battery.
Weirdly, it seems that the heavier item, the battery can go on the muffler side of the GNAT, the receiver on the other side of the fueselage and laterial balance is pretty good. I don't undertand why that would be a case, but it's a GNAT and some things just work!
I just saw a suggestion that a small plastic box, say a soap box, can be used to house the receiver. In that case the box can go either below the wing - and then act as a linding skid, or ontop behind the fuel tank.
I'm not sure what that red wedge thing is about, maybe scrap, or just to make it look nice.
As to launching it you can give it soft over hand toss into the wind, have someone do it for you the first time because you will need to trim the plane.. be prepared to us alot of down trim your first fight.
If you are patient sometime this weekend a combat site should have some info and a couple of short videos of launching. It's Wild Wings Combat [link]http://www.wildwingscombat.com[/link], they are just up and running take a look.
