Default rx antenna

What's the standard for rx antenna installation for nitro planes? I had a few foamies and taped the antenna to the outside of the fuse. I don't see too many nitro planes with the antennas on the outside. Should the wire just be strung out inside the fuse? Route it out the bottom of the fuse and attach to the outside? What works best?

Thanks

Well, if using 72 MHz, it should be as straight as possible. It can be inside or outside, whatever is convenient. Just do NOT cut the antenna. It must remain.. MUST REMAIN the same length as new. That is critical.

For 2.4 GHz, well, you are pretty flexible with that because it is very short. The only requirement, if it has a pair of antennas (meaning a "satellite" receiver"), it is supposed to be perpendicular to the plane of the other antenna.

That's about it.

Some say that it should not be inside the fuselage (72 MHz) when using metal pushrods. I tend to agree with that, but there is no facutal truth, as far as I know, about inteference from metal pushrods, but I just avoid the proximity. Keep it simple and avoid any potential problems...

Here's a couple I have run outside and connected to rudder with rubber band, just make sure you have some stress relief inside coming from rx. The U-Can it's coming out from under canopy, you can even come out bottom and tape it to bottom of plane.

I run them into a thin tube (For stiffness) and then slide the tube down the inside of the fuse (metal pushrods or not)

Been doing it like that for over 20 years now without even a glitch.

I like to glue small 3/4" sections of either fuel tubing or controll rod tubing underneath the fuse and run the antenna through them. I dont like the cluttered up look of running them topside and when the plane is in the air, it's closer and doesn't have to go through the plane and it's electronics. Not like being 4" closer will help, but what the heck?

Beside the SS in pic is a SSE it has a tube that I used like Minn just described, if you look under it you can see it on ground, I fixed that by taping it to rudder so it wouldn't drag ground. I had the U-Can run threw a tube inside, but had glitches, which I think came from z bend on throttle (metal to metal) just didn't run it bk threw tube. I'm gonna change SS to inside just for looks

If you do decide to run the antenna through a tube inside the fuselage, you must do two things: 1. Put a strain relief to prevent any strain on the antenna at the receiver. 2. Make sure you put something on the end of the antenna wire right at the end of the tube to prevent the antenna from snaking back into the fuselage due to vibration. A little dab of hot glue will do just fine and you can remove it if you have to.

That can and does happen. If it does ha.ppen, you will end up with a ball of an antenna at the inside end of that tube, all jumbled up and tangled, which will make the antenna pretty much useless.

Thanks all. I'll try running it in a tube inside the fuse then poke it out the back and secure to the underside of the fuse. That way i'll be sure to need a new one when the fuse snaps in half during one of my training sessions.

That will do the trick.
