You need to learn to accelerate to the jumps and then shut it down if required for the jump. Usually letting off before a jump and letting it roll up and over is enough. The jump will scrub speed if you are not accelerating up the face. Some jumps you need to power through others you need to coast through. I don't know how I will drive the current layout but if you are still having problems by Sunday hunt me or any one of the Losi drivers down and we will help you out in practice in the morning. I will need to get a pack on the track to know how it flows but I usually show up with charged cars to throw down right away.
