RE: Antenna wire
My late brother was an electronics geek and had lots of background in ham, CB, RC, computers, guitars and amps, etc. He said the coiled-antenna didn't affect range, so long as it wasn't passed over itself. I've used it on small planes and helis as well as the dean's whip, never a bother and range is great, never a glitch. I also use a rubber ducky antenna on my heli transmitter, also with no range reduction. If using the deans whip, tape or secure the whip to keep it from vibrating. If not secured in some way, it will vibrate and fail from fatigue stress.
