To be honest the diffs were something I was not sure of myself. I stayed with 7-7-3 here, maybe go to 5K in the rear but that was one thing I was curious to see someone else be ginea pig on

The problem with a fast servo isn't generally the initial speed. One of the most common issues found in servo setup is generally not setting a delay return speed or a negative exponential curve in the steering.
If you set that return delay to about 75-80 percent, you will instantly notice a stability increase. Don't mess with your initial speed. That is an advantage.
The steering curve should be set to react very quickly and then to smooth out through the rest of the range so that you and make the snap adjustments you need in the technical sections.
Tune your initial delay, or over all speed to suit your driving style from there.
If you think you are still being twitchy, I suggest going to a larger steering wheel on your remote. You will notice that Spektrum generally has a larger wheel and a more linear curve. What they lack for quality or the controversial link connection issues are made up for by their smooth ergonomic mechanics. Airtronics and Futaba have a smaller wheel and this is often confused for a faster system. Fact is the wheel is smaller and the trigger swings more which cause you to make larger actions quicker.
In realistic factors, the human can't decipher the speed indifference that the top radios are producing. But the mechanics of the radio is different and depending on the driver, one will suit you better than the other due to your precise ability. That being said, sometime "slow is fast", and that sometimes goes for servo actuation set to per user optimization.
If you don't have a mid to high end radio, you will find much benefit in owning one for these very reasons once you understand how to utilize it's features that many ignore for the most part.

A great feature of having a dial that you can mix with an expo is the ability to make a expo curve on the fly without having to get into the programming to tweak your feel on any track. Here is a video I made demonstrating an expo set on the throttle. This makes an artificial punch adjustment that I can set as I drive around a track depending on the traction available during a race if I want. You can also utilize this feature for steering speed/delay/expo. Which ever you want to set as the dial.

personally using futaba radio systems here I find that I run anywhere between 10% to 20% negative exponential on the steering. It helps calm down how aggressive it feels on initial turn in so my movements on the wheel don't need to be so minor to affect the amount of steering I am wanting.

As I have an another SCT410.3 here that my daughter uses in sportsman class with 50% power, maybe I'll tinker with the diffs to see how this 15-15-10 setup feels.

If you can post of video fo what you are seeing I'd be curious to watch it.

What did you guys use to glue holes in the pistons? Tire glue? I'm going from the 10x1.2 to the 8x1.4

last few times I have done this I have used jb weld. If the oil pushes past that we got bigger problems

I have heard of people using toothpicks broken off into the holes and then glue or something similar to seal it up.

I think I am going to go back to stock diff oils, my truck was hooking up great with them. I only changed to see if it could be even better! haha, but its awful now.

Thanks for the info man, I use a Futaba 3pv currently. I want to upgrade to the 4pv or 4px eventually though. The MKS servo and diff oils were changed at the same time, and it is impossible to drive currently. I set the endpoints, but never adjusting delay or neg exp. I will need to look into all the settings on the 3pv and see what I can work out. That is definitely a good idea though. I really appreciate it!

Thanks for being first on the beach!


I use the 3PV here too, had a 4PLS but after getting my daughter a 3PV I liked it enough that went with the radio for myself and my other daughter. It has the features I need and works very well for the money.

Glad to hear it has the features, I was worried it wouldn't! Do you happen to know what all you adjusted on the radio? I have my 3 cars on the radio, but have only messed with trim really... turned down the d/r before, but never neg exp or return delay.

I had a chance to run Joe Bornhorst's Motorama setup this past Saturday night and loved it. The truck was dialed. Managed to put myself 3rd on the podium (my first time ever on the podium).

I ran Joe's Motorama setup, which is based off of the Tekno recommended setup, this past Saturday and loved it. Truck was easy to control. Track started grooving up but with dust in some areas. Give Joe's setup a try.

I adust EPA to control how much throw each side gets. I also then adjust subtrim . From there during practice I'll play with the exponential on the steering. Usually ended up with 10% to 20% negative expo. I haven't played with return delay personally.

The negative expo for me made a big difference as without it, the steering would feel very twitchy due to how far the servo would steering relative to my steering input.

One other thing that helped even though I don't have the new steering rack components was going to the front hole on the steering rack. That change alone made a big difference in how the steering reacted. It calmed my truck down a lot and on my EB48SL it was too calm so I moved back to the middle position.

What diff setup did you go away from? I am assuming the change in fluids to something heavy like this may have helped to calm down how fast the rear end can come around as with light rear diff fluid it can be a bit rapid?

I ran 7/10/5 last summer. Switching to the heavier diffs fluids planted the truck better. I could push through the turns a little harder. It did slow down the rear end coming around so quickly. But still able to get a little loose to be able to rotated the truck around.

yeah, thats what I was thinking it would do. Its funny its like when you read the setup guides, it mentioned that you can get more traction to the rear with lighter fluid however it rotates faster. So if you lose that traction it can feel inconsistent. Part of me thinks it cutting down on that rotation is the big thing.

Hmm, maybe I'll give that a look lol.

How was the nose down issue with the shock changes and bump handling?

Make sure to check your radio as to how you set your expo. With my Spectrum adding positive expo on the steering makes it less sensitive at center. I usually run mine at +20.
