I've been flying a Perfect on 50 MHz for awhile. I've been as far downwind as I can see the plane with no problems. On all my planes (50MHz) I run a long antenna (about 1.5m in length--close to 1/4 wavelength) that exits the fuse near the left TE and is taped to the outside of the fuse. It extends aft and goes to the bottom of the fuse a couple inches forward of the rudder hingeline. >From there in enters the fuse and goes up the inside of the fin, up to the >tip. I use solid insulated wire, so it's stiff enough to stay upright inside the fin (the top half of the fin is fiberglass).
My normal receiver antenna is cut 3 inches from the Rx and the long antenna is soldered to it. The antenna stays with the plane (so do a neat job of taping). If a receiver is changed, just unsolder it). As usual, do a proper ground range check. This also works for V-tails. My Superior has the end of the antenna running up the inside of the right stab hingeline. Its easy to pull out if you need to remove the V-tail (mine usually stays attached unless I need to ship it). The other method that has been successful (72 MHz and 50MHz) is to run the antenna inside the fuse and let it exit from the bottom of the rudder hingeline, extending about 14 inches into the airflow. I prefer the outside of the fuse and inside the fin (I don't like stuff hanging from the tail of my planes). Hope this helps.
