I was curious if anybody has experienced mechanical failure with a whip antenna before? I searched the posts but couldn't find any information. I have a base loaded antenna in my Raptor 50. A few weeks back I was flying when the heli went out of control. Just before impact I regained control and managed to land it. After shutting the heli down I inspected everything and couldn't get the heli to glitch. A range check with the engine off checked out ok. When I started the heli up, the glitching started back up. While the heli was running I noticed that the white wire that fits inside the whip was vibrating. I gave a gentle tug and the wire came out of the whip. The wire had broken at the base. The failure wasn't at my solder point but in the antenna itself. The heli is balanced well and I have no visible vibrations while running, but I can't rule out failure due to vibration. The antenna is mounted in a protected position and has never been bent, bumped, etc. I'm wondering if this unit was defective from the start? I'm hoping this was just a fluke and not a trend. I've replaced the antenna and have six flights with the new one. I haven't had any problems with the new antenna. Has anybody had a failure like this before?
