Cool just checking. I have heard of this happening with a 2.4 system, rare, but it does happen. Try running it in a differant location. There may be something in that area affecting it, cell tower, police radio repeater, etc. Secondly, worst case is try another brand of TX and RX. There's so much electronic noise nowadays, I'm surprised any of our stuff works lol. I have a mini Losi that I have replaced esc, 4 receivers, 3 controllers, and it still has a short range, @50ft. Luckily it just rolls to a stop when it loses range. Nitros aren't as forgiving. I still say try another 2.4 system.
