What radio system are you running because my stock radio will go for a min or two. Then it just stops and servo twitches for a few, then it will take off for a few more. As long as im real close to it, it will keep running what do you think? Is the radio going bad? I really love your video mine from what I can see almost hops up as much at start then it will die out at about 100 feet before I can even turn it around. I did turn it atleast once and flipped it.
