No flaming.. just advise as RCKen said. The antennas are a specific lenght to match the frequency you are using. Bending it back on itself is like not extending the TX antenna all the way. It will work but will not work as designed. It may be just fine with all normal, fully charged batteries, and so on, but get marginal and you will find out how different it will behave.

Try running the antenna along the fuselage and up the vert stab and along the top and put a small length of tubing to keep it away from the rudder and let it sail.
