I definitely agree slower can be faster especially with e-buggies. But that being said they are loads of fun, check out the video below, I took this a few years ago at Hot Rods and the track had a big table top followed by another jump up onto another table top. The best and fastest line was to downside the first table top and then take on the second jump separately. Just for fun and to demonstrate the brushless power (remember this was two years ago) I cleared the entire section. If you noticed I was a little excited and held the power on too long and got vertical so I had to hammer the brakes to get the nose down. Messed up my first attempt, the successful jump starts at 00:38 into the video.
