Is the glitching that people are experiencing causing the car to be uncontrollable as if there is someone on your frequency?
Or does the car and controller just shut down for a moment?
My 4px is working as expected, but the last time I ran my nitro truck, I did lose throttle for a very brief moment. As if the fail safe kicked in, but then I quickly regained it. I went onto the straight and the truck slowed down to almost a stop even though I was a WOT. I regained the throttle control, but I thought something was mechanically wrong with the car, so I pulled off. I checked over the truck and nothing was broken, and I went back out and the truck worked perfect ever since.
So now I'm thinking what if it was a momentary brown out? Battery was fully charged and the straight away is the closest part of the track to the driver's stand. Using the stock receiver and KO RSX servos. Life in the Tx and Lipo for the Rx. I've been running twice a week since I got the controller from Tower around Thanksgiving, and this might be the only potential issue (if it is the controller), and I've run R304SB, 614ff, and 614fs receivers. And I tend to run with the antenna down without any issues on a 200X150ft track.
