Just got a new tqi 2.4ghz transmitter with 5 channel telemetry reciever combo. I've calibrated and linked to my castle creations SV2 esc wit no problems. Steering and throttle respond correctly. However when I set the car down on the pavement and hit the throttle the car seems to jerk toward then lose connection/power for a fraction of a second and then jerk forward again and again. After a few seconds of this behavior the car will respond normally even if I increase speed and distance,however, as soon as I realease throttle back to neutral/brake the problem starts happening again. Any ideas?
