Running an RS Pro (1.89 fw) in 1/12 scale 17.5. Motor timing at minimum, full boost (Trinity Duo), rollout of 3.33 inches, neutral 15, drag brake 40, brake strength 60, no current limit. At the start (from a dead standstill) the launch is pitiful. Within the first 15 feet or so, people pass me like I'm sitting still. Is this a V1.89 firmware issue? A few others are running Tekin RS/RS Pro and don't seem to have this issue.
After the first 15-20 feet, the car is fine throughout the rest of the race. It's just starting from a dead stop.
