Hi,

When up the field one day one of my fellow club members pointed out that i shouldnt have ANY receiver wire in the fusulage........ Is this true ?

I normally have 80 percent of it out and the other 20 percent inside due to the fact if pull all the length out its just too long and may get caught up in the elevator or rudder when flying as most of my planes are 40 size planes............

If its not ok to have any inside the fuse, can anyone recommend a different way to do this ? how do you attach yours so its not too long outside. I do range checks and they seem ok on the setups i use but after his comments its now started to make me wonder.

Thx in advance for any replys

I have my just like yours and didn't have any problem so far.
I had couple experts looking at my plane and even suggesting the wire the way it is.

You have me a bit concerned now. I just built a plane and have the antenna coming through the top of the plane. I think the important thing is that you don't get the antenna wire too close to the servo wires and get electrical intereferance. I hope we get some responses from some more experiences people, but I am under the impression as long as it is not close to the servo wires it shouldn't matter. At least I hope not [] . . . .

Your setup seems fine to me......where your antenna exits the plane from inside the fuselage, thread the antenna through a button. If the plane crashes and the wire is broken, it will be saved between the button and receiver, then you can solder on another piece. Usually you should always measure the length of your antenna just in case you have to resolder.
I have my antenna hidden inside the wing of my plane and it fly great without any glitches.

Having some of the Rx antenna wire in the fuse is not in itself a problem. Most giant scale planes have the whole antenna within the fuse. You don't however want any extra wire to be coiled up or doubled over on itself as this can affect the range. On my .40 - .60 size planes, I usually use a rubber band for strain relief from the top of the fin and let the extra wire dangle behind. If you feel there is a chance of it getting caught in the control surfaces then seal them with MonoKote or whatever so the wire can't possibly get in between. So far I've never had a problem with that.

Even on 40 size planes I always leave the antenna inside the fuse. No problem.

But like jammer said, you don't want it to be coiled up, But if it's too long to fit inside, I have run from the Rx, to the forward wing bulkhead, and then back again with no problems.

As has been said, don't coil it or leave it doubled over on itself.

I run my x wires the same way most sport flyers do. In the picture below, the receiver is actually located at about the front of the canopy (inside the fuse). The wire runs under the servos to the plastic tube seen in the photo.

Here is another related question,


Does it matter if you run the wire through push rod tubing or spray paint it?

Plastic push rod tubing is fine and works great. Don't use carbon fiber. I don't see any problems with painting the wire as long as there is no metal in the paint.

I hate running a wire on the outside of an airplane. If I can avoid it then I usually do. Take a look at the giant scale planes. We hardly ever run the wire on the outside b/c its ugly.

I wouldn't let the excess antenna trail behind the airplane if you are flying combat, but no sweat otherwise. BTW, antenna wires are normally one meter long, measured from the circuit board...JIM
