The 3:1's will go from full speed to a a dead stop for a split second in longer grass when it gets bound in the sprocket (why are these modern tanks such grass hoovers?!?), but they will break free before your brain can tell the remote to stop. The 4:1's just tear the grass with barely a noticeable pause. My fear is that the weight required to stop the toyish bounce will also cause the sprockets to chew more grass.

I'll put a detailed update in my thread by Saturday once my roadwheels are painted, installed and I've had time to test different loads in the hull if they are required. The 3:1's actually perform exactly how I want them to turning and control wise when the battery is low enough to dim the headlights. Maybe a 6v battery is the answer.
