Among all the pattern fliers that I know, we install the antenna inside the fuselage without any reception problems.

The way that I do it is to install a piece of clear antenna tube...from Dubro in the fuselage. Some folks glue this inside the fuse at several points. Lately, I make a block of balsa with a hole drilled at an angle so that the tube is held against the floor/top of the fuselage tail (internally). With the antenna tube installed, lubricate your antenna wire with baby powder (corn starch) and slide it into the tube. Use a piece of tape to keep it inside the tube.

That's all there is to it.

You just won't find pattern folk with an antenna on the outside of the fuselage.

Cheers,
