Oooooh. I'm trying these out right now. They look awesome, and the ability to do donuts is attractive to ay the least. Any plans for probe and truck sized versions? Not necessarily new models, just resized ones with retuned suspension and traction settings? Edit: After a bit of testing I've found out that A: I absolutely adore these things, and B: The CFG tuning is a bit off. What I've changed: Braketorque. These slide, so I see no reason not to put enough of this to lock the tires up. Changed it to 2500. Steering lock. Because they slide, steering too much at speed will jsut result in under/over steer instead of a rollover. Plus I've had a few spins that could have been easily corrected if I had more steering lock at that speed. So I turned this up across the board. Slow speed is up to 35 degrees, high speed is up to 25 degrees. I use a 360 pad to drive rovers so it isn't a problem for me to manually steer less than that. Torque. The initial value of 2500 is good, but I felt the value dropped off way too quickly. Mine stay at peak torque until 30m/s, then slowly taper off. At 50m/s they're still putting down 1250. This gives my rather light(Under 2 tons) medium sized space car a top speed of about 45m/s, which is perfect. What I'd like to change but cannot: Spring rate. My medium sized rovers are incredibly lightweight, and as a result there isn't much action from the suspension. These feel to me to be tuned for 4-6 ton rovers, not 1.5 ton rovers. I'd turn the spring stiffness and dampening down quite a bit for them. Or maybe make a second "Type R" version with the lighter tuning for lighter medium sized rovers. Sizing. As mentioned before some gokart and truck sized versions with varying stats would be great as well. I could handle scaling them through part.cfg, but not changing the springs rates to suit the different types of vehicles. Traction. The sideways grip is about spot on I think, but forward bite leaves much to be desired. Even with my 360 pad every takeoff is full of wheelspin. That might just be because of how light my rover is, but I'd still like more forward bite. Maybe another 20%. But leave the side bite alone, again, I feel that's spot on. It's still possible to traction roll but you really have to eff it up to do it, and that's about right. Edit 2: Powerslidepowerslidepowerslidepowerslide If only we could differentiate the surfaces. The slicks would work best on the runway, or other bodies like the runway, while the knobbies would slide like mad on those surfaces and dig in firmly on dirt and loose rocks.
