I rode on the JR train for as long as I could. I even went with their hv servos when they came out. I had one of those blow after 2 track days. Ao I ripped them all out soldthem and have been with hitec ever since. I did have 1 7940 act funny so I sent it back but now that I think about it my lipo was prob acting funny. Once you go hitec you will never go back. Haha.
