Receiver antenna question?
I have a Kadet Senior that I turned into a tail-dragger and bought an antenna tube from the LHS. I want to know if the tube goes almost all the way to the rear of the plane and the antenna comes out the other end of the tube if I can fly like that or if it still has to come out of the fueselage at some point. The tube is inside the fueselage from the reciever to about 6 inches from the open end of the fueselage by the elevator. It really is a much cleaner look!
Thanks,
Gibbs

RE: Receiver antenna question?
No; the antenna does not have to exit the airplane in order to work.
What you need to do is ensure is that the antenna is fully extended (no major bends or kinks). We have seen people that wanted that "Clean Look" and they actually COILED up the antenna in order to make it fit inside of the AC.
This has the effect of shortening your antenna and 'REDUCING' your range. - you could loose your AC if you let it get too far away. []
The average antenna is 39" long, if you can keep that much antenna inside of your AC (in a strait line) - it will probably work just fine.

As js3 stated the practice can be effective if done properly and has been standard practice for some years in RC pylon where the the drag penilty and the danger of a following aircraft of cutting off your antenna if left hanging for about fourteen inchs if done the old way.
Attend any 422 or 428 pylon event say at the nationals or any event and you will have trouble spotting any anternnas. These aircraft can and do approach speeds over 170.
I also have used the technique on many warbird racers these typically are slower but much bigger airplanes and indeed it works quite well.
For normal sport airplanes I usually don't bother but for the racers yes indeed.
Here is a little tutorial on how its done:

And a few pics ot the installation in progress on a warbird racer.

Au contraire, the antenna MAY be coiled up inside the fuse and still provide more than adequate range for our purposes. You just have to make sure that it is coiled CORRECTLY.

JS3's comment was "more than adequate range for our purposes",
I said "This has the effect of shortening your antenna and 'REDUCING' your range. - you could loose your AC if you let it get too far away.
The key here is to keep your plane in close to the field, so that you do not exceed your reduced range. Easy for an experienced flier that has a tight grip on the flight envelope (racers and Scale types) but for a novice - the AC can move out of range in a hurry - which is what I was trying to say...

It would seem that we are both agreeing on the subject, the plane will work with a coiled antenna - you will just have a "REDUCED RANGE"

Yes, yes, I agree and acknowledge that doing anything with the RX antenna other than having it run a straight path will reduce the effective range. My point is that it will still provide and retain control for a smallish (.40 to .60 sized) plane well beyond the normal person's ability to see what the model is doing.
