Thank you much appreciated. I have not raced true 8th scale thus 8th buggy or truly as I have always been a 10th scale fella. Anyhow I have seen the great fun the 8th scale buggy and truggy racers have at our local outdoor race facility, thus I plan on joining the fun. Going to purchase this buggy.

Totally Agree with you Cain. OH! Your old DESC410 is running dialed. Just put a new HW XR8 SCT pro, and HW G2 4300KV (short can) in her.

So the steering is more controlled as in less steering?
On my .3 I took out a defective mks 599 because it decides on its own if it when it wants to change its center, where I'm continuously needing to adjust the steering trim. Servo saver is tight and everything turns freely. Swapped it out with ko propo rsx which had no problems.
What happened was that I could drive the car harder. Much more predictable, stable, consistent and I was faster. Rotation was under greater control.
Bornhorst uses the mks 599 and for whatever reason the car was twitchy with it, at least for me. Lutz uses a super fast futaba that might be causing the same issue. Point is those two team drivers give their feedback to tekno and because of their super fast servos the cars are harder to control. Therefore the new steering on the new .4 might not have been needed. Maybe except on carpet, but I wouldn't know because there are no carpet tracks where I'm from. I may be wrong. It was a big shock to me that handling was so different from a servo change.
What I'm guessing is that because this buggy already has responsive steering, adding a responsive servo is too much. It needs balance between responsiveness and control.
BTW I spoke with mks customer service and team manager Kenny. Still waiting to get an email or call if they will service this new defective servo. They are polite and their words sound promising. Will update this week if mks is a brand that stands behind their products and if they should or shouldn't be recommended.

The new .4 geometry allows it to keep the same type of turning radius as the .3 vehicle without the rear having to break free to do it at speed, and without the front scrubbing as hard, making everything more controlled and in many cases raising corner speed. It isn't a mechanical straight reduction of steering like you're thinking of (which is what the steering stops did for the .3 vehicle).

Example would be that tekno can do tighter corners than kyosho, but it doesn't mean it is better. When comparing the .3 steering to .4 has the steering gone down a bit to gain more stability? Or does the .4 steer just as sharp and tighg, but more stable making it faster?

I ran my .4 for the first time this weekend. Used mostly Joe's smooth track setup.
http://www.teknorc.com/wp-content/up...moothTrack.pdf
Overall I really like it, I think the setup is pretty close to where my .3 was. I was hoping to get another motor in time so I could run them back to back, but that didn't happen.
I noticed the inside of my front wheels rubbing on something, I was thinking that it was the front side of the outer hinge pin, but the scrape marks inside the wheel were pretty smooth so I think it may be somewhere else. I cant get it to rub on the bench but it is really close in a few spots so I imagine its happening when the wheels are flexing some.
A couple of times I had a weird thing happen that I cant figure out, the buggy would dart off in one direction (mostly to the right IIRC) a couple of times it was while i was on the brakes, and a couple under acceleration. I cant tell if it was because of the bump steer or a by product of the front wheels rubbing on something.
The build went really well. The shoulder screws that go thru the bearings in the new front spindles were difficult to get started threading into the plastic. The o-rings for the bleeder screws are super tiny and take some patience to get on. And the rear hubs call for and only give you a total of 5mm of shims, but with that there is a fair amount of fore/aft play so I added another 1mm shim. Everything else went smoothly.

I've been watching this thread to see what complaints or if anything is prone to breaking. Hope this proves to be a good buggy.

Looks like its a tight squeeze but doable. Hope this helps.
