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 the brake pic time out to 3000 or 3 seconds with no change in the issue. As soon as the door closes the car drifts up a little then runs down, you don't notice it in the up direction as much because it's going up anyway. Anyone else experiencing something similar? It's possible we are missing a step in the saving process but I would think if it still shows our changes after we cycle the power it was saved properly.
