The whole point of making a coil inside the fuse with NO wire hanging out in the breeze is to reduce drag. These 1/2 A Racers weigh less than 12 oz and the engines turn up more than 30 Grand. Top speed has got to be close to 90 mph, maybe faster. Any additional drag will make a significant difference in speed. ALSO there are two kinds of range, radio signal range and eyesight range. As long as the first exceeds the second all is well. Like I said in my post above I've been wrapping my antenna around a drinking straw to make a COIL for many, many years and have no problems. I'd like to say this is cause I use JR radios but there are a lot of other people out there with Pylon Racers, 1/2 A, Q-500 and Q-40, that user Fubar, Hitec and Joe Blow for all I know.
