It was wet and grip was not optimal. However, I was able to consistently clear the quad without problems. The triple was also possible, even though not as easy as with the Losi. However, during racing nobody really attempts it as it is pretty inconsistent due to the long flight time. We typically only do it to gain time on a last resort basis and it's only like a 50% chance you will land right and actually gain time.

There are several things that I feel helped my truck out: For one, the 550 motor. For my PERSONAL preference, it makes the truck easier to drive on the big track. I like the extra weight of if and where it is. With new gearing on an SC4x 4.5, (14/58) with a Tekin RS Pro in dual mode the truck had almost the same top speed as the 4600, however with less punch. This translated into much easier throttle control, which in turn allowed me to run the truck at 6lbs 2oz. The lighter weight seemed to allow the truck to jump much better and longer too. The landings are far less harsh.

For drive I ran a clutch basket with HD pads. We tried our own version of a center diff, and while it felt good through the corners and rough sections, it suffered leading up to jumps, it felt like it was diffing out. It's almost like an 8th scale with too light of a center fluid/ empty center diff.

The clutch basket had much better forward drive and was a little loose on power. Nothing that was too bad though. However not as stable as the Losi truck.

Another thing that I think suited the track was light diff fluid. Running 3k rear 5k front. This is what I run on my SCTE, so I figured I would give it a shot. I still am not sure about it, have to run it in more, but so far I have liked it.

Now I am just waiting on a pinned top shaft to try that again. We'll see. At least the jumps are doable. I do think that part of the problem on the jump is that the right line to take is only about 3 ft wide. This is really hard to hit every time correctly on a track this size.

Above is a picture of the truck.

Its been proven by more than a few as well as at least two Factory AE drivers that claim the same thing. I happen to be pretty decent at shock adjustments and spend more than 5 hours at tracks during the week. I dont know everything but I know alot, my truck is better at it than before but still not near good enough.

Low speed approach 30' triples are not a problem its the 40mph 36' jumps that are an issue and not everyone has access to these types of tracks and I didnt until recently.

Good news to hear that jump was possible after all ...



Happy to hear at least one Sc10 4x4 can do ....

They will be available in black only at first though, and should be available in like a month according to my sources at Avid. They are modeled after KMC Rockstar wheels, by far the best looking and best wheels I have tested for SC trucks to date. The attention to detail makes them better.

I agree that the Losi doesn't really have better air control. Once that nose is down or up, there is no way to move it. The air pushes on the body too hard and loosing control of the truck in the air pretty much is a death sentence with an SC. 2WD Trucks are even worse!

WC, yes, the jump is not easy, and I do have to be lined up better because I have less power in this truck, but the jumps are certainly doable. Lap times, I did not get to compare, but I still don't feel like I have the same amount of corner speed as the Losi, but in some jumps I felt like it was better.

Note: Corner speed is not the same thing as steering or rotation.

The trucks are just so heavy and powerful that when the power gets down, it typically slips, especially going over ruts. This made it hard to accelerate going up to big jumps. In the corners though, it was a dream.

WC, I don't think a different belt would make much of a difference. On the corner speed, something has to be done to equalize power so that the gas can be mashed and the truck can shoot forward, rather than step out. I have a feeling that a center gear diff, even if it is not fluid filled, and a higher rear roll center would make the truck better.

Easy fix though. It did jump considerably better. We have a new layout now and we will see if it works on the new layout too.
