I need some help with my spektrum setup. I'm running a KO EX1 Mars R Transmitter in a BJ4 with LRP Sphere Brushless setup. The problem I'm having is this:

On somewhere between the 1st and 4th lap the system will lose connection and therefore lose power on one section in the middle of the track. The car loses connection on the face of a double jump and lawn darts into the face of the landing. The car will then power back up and go again. This will happen maybe 2 times per heat. It's always in the same spot and it's always within the first 4 laps.

Any thoughts on what's going on here? I've tried swapping out recievers, I've checked and double checked the internal Antenna wiring. I'm running out of Ideas.

Thanks,
Blake
