From what I understand it's good to have a little peeking out of the fuselage. The reason? It is so you will have a better chance of getting the full range, and less chance of a glitch or interference from your own electronics, pushrods and etc.

I have not ever completely hidden a 72mHz antenna in a fuselage, and for me to say to do so is not copasetic. Different radios have different signal strengths, so to be safe I suggest that you have at least 1-2" sticking out of the fuselage or get a whip antenna to be safe.

If you don't believe me read this:

It talks about the different antenna experiments and explains the basics on how your RX works. You can come to your own conclusion about it like I'm sure you will, I only gave you my experience in what I do to hide the antenna without loosing range. If you were to look at my planes sitting on the ground, you would think I was running 2.4GHz until you saw my transmitter.

I have a inch exposed, but you wouldn't see it on the ground or in flight- you would only see it if I flipped the plane over, and pointed it out to you like I did when I took the pictures.

Having a inch or so sticking out helps to get a better signal in my opinion, less junk the signal has to go through. I don't know if that's true or not, but that's what I believe, and to me it makes sense. Hope it does for you?
