Seeing Joe's plane at the Tune Up made me realize that there are folks out there who have never gone through an RC phase, and yet may want to try using radios for Carrier (or, for that matter, scale).
So here's some pictures from my shop, and some explanations. This is basically what I told Joe at the meet, with pictures of what I wished I had in my truck to show him.
Somewhere on the net there's probably a much better presentation -- Google around, see what you find.
When you go and put a radio (or any other electronics) into a glow-powered plane, there are two basic incompatibilities that you need to remember: One, engines vibrate, but electronics don't like being vibrated. And two, engines spew oil, and electronics don't like getting oily. Of the two, the vibration problem is by far the more important one.
Always protect your electronics from vibration. Always. Receivers and batteries need to be wrapped in closed-cell foam rubber, and the foam bundle put someplace where it'll stay in place. The top picture shows the receiver mounting in an RC trainer. What you see is the foam that's wrapped around the receiver, tucked into the fuselage just ahead of the servos.
Don't use just any foam -- you want real foam rubber, and you want closed-cell. Any real hobby shop carries it. You'll get a big square of it, and cut off sections to wrap your stuff in.
I put these pictures out of order -- oops. The second picture shows the battery wiring, with switch, charging jack, and battery. Note that this is sitting on a pad of that foam rubber.
You can't wrap your servos in foam and shove them in a hole -- but you still need to protect them from vibration. The third picture shows a servo out of a plane (who recognizes that servo?). This servo has four mounting holes. Each one has a rubber grommit, with a screw through the grommit. When the servo is installed, you tighten the screw just enough so that the grommit grips the servo, but not so much that it gets chewed through. You can get servo mounting kits at your LHS; these come with screws, grommits, and brass ferrules that you can use as standoffs. The DuBro kit has a picture on the back showing what to do.
Mount the servos to a pair of rails (seen in the top picture) or into a plywood tray, or into a hole in some plywood. The wood should not touch the servo anywhere -- if it does, it'll transmit vibration. Instead, there should be clearance all the way around, and the servo should be located by grommits. The fourth picture shows a plywood servo tray with one servo taken out -- and, right ahead of the tray, you can see the foam around the battery pack.
Guys that fly profile RC planes usually make a radio compartment in the wing. Looking at Joe's plane it looks like he could do the same thing. The usual RC way to do it is to make the compartment entirely behind the spar, where the curve of the wing is less. I'm showing a compartment that goes both in front of and in back of the spar, because I know that Joe is retrofitting an existing plane, and wants to maintain balance. There is no reason, particularly on a new build, why you couldn't make this compartment on the bottom of the wing and put your servo in the lid -- that way all of your wiring will be hidden, with just the top of a servo sticking out.
Another advantage of putting the compartment back there is that the servo is out of range of getting raw fuel dumped on it. It'll get some exhaust slime, but that's better than raw fuel. Putting the servo entirely inside the wing with just a pushrod coming out would be the bee's knees, but it's not necessary.
If you're cheap like Joe and me, then keep in mind that nearly every RC guy in creation seem to have spare servos, and a lot of them have spare wiring harnesses. Some may even have spare batteries (I don't know if they still do, but the last time I bought a complete radio it came with transmitter, receiver, servos, switch harness, and battery -- if you fly electric, the battery and switch harness get left in the box). If you want to save $10 or $20 and you have RC friends -- ask.
