I think I agree with Socket on this one which I'm adapting from wheelbase. A longer wheelbase gained from the adjustments at the rear of the car put more weight on the front and less on the rear giving the front more grip and less to the rear and is felt when braking into corners. The light rear is more likely to drift around. This is based on the weight bias on the tires. If that longer chassis keeps the weight bias the same as the shorter chassis then the guide is probably right. I have not tried the longer chassis, but that is my theory.

I'm going back to the original chassis that came in the 815 kit, and see if I can get it to drive better for me as well.

Sure, Do I know you? I have seen many of your post, and I haven't, raced much lately to ask anyone at Fearfarm, who are you? If you race there often, you surely know who I am, Veno sr.

I have the new chassis, and I think it is as Socket states, way more steering, and to me, makes it a hand full to drive, like the front end is pinned to the ground, and the rear is loose as can be, that's with all the other stuff that it required that I had purchased and installed with very little difference if any, to make it handle better, for me.

I'm certainly not a setup expert so I use setup guides to help. Everything I see says shorter wheelbase = quicker steering response and increased steering off power on corner entry. Longer wheel base = decreased steering response and less steering off power on corner entry but more stable and better in bumpy conditions. That said, I haven't had a chance to drive it with the stock chassis yet so I can't say for sure how it compares. Hopefully I'll be able to get it on the track Thursday and test it out.

I would think it depends on where the 4mm extra comes from, for instance if its behind the motor before the rear diff, then thats going to affect your weight distribution alot, less weight over the rear tires means less rear grip, which would be give more rotation/steering. It might also make the car more or less prone to the effect of weight under acceleration/deceleration too. Like when your rear sags under acceleration it gives more rear grip, it might resist that sag a bit, more leverage.

Ty had said it was built with astro and carpet in mind, however JT and Savoya ran it at fear farm fairly successfully.

If I drove like Ty, JT, or Savoy, I probably wouldn't have any problem driving the buggy either, a pro can drive most anything, and be faster than most non sponsored driver.

Stees and I ran the regular chassis in the main. I was a second off of them, but Stees was right in the mix. I think it's more about driving style with the extended chassis.
#1512
Yea, I drove the 812 better than the 815, but you guys are in a different class than me, what is your name Socket, I'm sure you know me from Fearfarm.
#1513
...I am re-thinking some wording on the longer chassis....
Veno Sr, can you post your D812 set up and your D815 set up? I want to do a mental comparo and see what the issue you're having is.

Give me a day or so, til I can dig it out, I haven't touched RC stuff in a few weeks. Been busy with Doctor stuff.

Some comments from the Pros on the long chassis...
