I am having a problem with a Gen2 in that it drifts up a little before taking off. I tried lengthening the brake pick time but it doesn't seem to make any difference. I know it's saving ok because when I reset the power the change is still in there, but the car is still drifting. I have set it out to 3000 or 3 seconds with no change. as soon as the door closes the car drifts up a little. Anyone else experiencing something simular?
