Don't ever buy anything form HobbyTron. They don't answer phones, they don't return emails, they make promises just to get you off the phone when you can finally get through. I am waiting to get a defective controller replaced. All the fun out of buying a hobby. After at least 6 phone calls with messages left to return my call, 5 emails to try to get my problem resolved, no one has called me back. On night I called late in the evening and someone named Nicole answered. She was very pleasant and said she would ship me a replacement product the next day or two. It's been three weeks and nothing was sent. Now they don't answer my calls or emials. RUN, don't buy from thes on line con artists.
