go to radio shack, get a phone antenna, take out the old one from the controller, and solder the blue or green wire to the antenna and bam 15 ft of range

not always...my hard antenna did not help one damn bit...(no pun intended )

while we are at it, my QFM solid copper antenna did not increase range either. The only thing that worked was taking out the cripple capacitor.

both of the antenna mods worked on TheFanMan's rx7 to a freakish point...bastard-guy
