I digress, when "years of experience" by rule somehow supercede imperical data based on hundreds of thousands of successful flights... Its not even a rational discussion anymore. All I can say is go to a heli fest with helis from micros to 60 sized helis or a electric 3D foamy competition and look around at their antenna configurations. If the dozens and dozens of successful flights dont conclusively show that the antenna can be sucessfully doubled without any problems I will eat my hat...

I will add this caviot. If you are going to do it it has to be done correctly.. If you do it incorrectly you will crash so if you arent 100% sure of how to wrap or double the antenna correctly,,, DONT DO IT.
