    Traction roll on pavement?

    I apologize if this has been asked before. How well does the UDR turn on pavement? I'm considering buying one, but will be running on pavement at least half the time, so I want a vehicle that will turn or slide without rolling at higher speeds and under throttle.

    If the UDR does traction roll, are there any mods that can be easily done to prevent this condition?

    Thanks in advance!

    Itís not really made for pavement and on dirt you need to stay on the gas so it doesnít traction roll. Iv never driven it on pavement but Iíd imagine it will roll pretty easy. Donít take it the wrong way but why are you buying a $800 trophy truck to drive on the pavement? I understand people can do whatever they want with it but itís an off road truck, you will be missing out if you donít drive it in the conditions it was made for.

    I have driven mine on pavement. If your careful you can get away without rolling it. Obviously itís not going to carve corners. It will slide but if it catches an edge or gets too much grip right on its roof it goes.

    I drive mine on pavement a lot when Im too lazy to drive to a good bashing spot. It will traction roll on pavement, grass and dirt. Its not like a rustler or an xmaxx where you just slam the gas and go. There is a learning curve for the truck. If you and high speed tight turning I would say this is NOT that truck. If you take the time to learn to drive this truck I know youll enjoy it like everyone else on these forums has. And slash2018 is right, you really should try and take it off road. If youre buying the truck for the scale suspension and details its amazing to watch that all in action. The videos dont do the truck justice.
    I'm the reason why we can't have nice things!

    Thanks for the responses guys.

    The scale realism is the reason I'm interested in the UDR, as Teae referenced. I had R/C cars and trucks when I was younger, but this will be the first one I've owned in over 15 years. This time around though, I'm not budget constrained, so I figured why not treat myself to something really cool, hence the UDR.

    I am limited on storage space however, and only want to have one R/C car or truck. My preference is a high speed scale off-roader/SCT, but I want to be able to enjoy it even on days when I don't have time in my schedule to drive to a dedicated bashing spot (this is where the pavement usage comes in). I know something like a Rustler would check both pavement and off-road boxes, but if I'm only buying one, I want it to be the coolest thing I can get my hands on. The UDR is still at the top of my list even knowing that it will traction roll, I just wanted to know what to expect before I plop down $800 on a toy.

    Thanks again, and feel free to share any additional ideas or information you guys think might be useful to me!

    I drive mine mostly on concrete/asphalt and I can say with some certainty that on those surfaces it likes to be driven to scale. That is, not bashed or jumped fifteen feet. Converting to an open rear diff REALLY helps reduce traction roll, but if pushed to hard, it will flip. And if you REALLY push it, stuff breaks.... probably like a 1:1. If you just want to bash, I'd say buy a Slash or equivalent. Maybe an X-Maxx. But if you're like me and like the whole scale suspension/driving experience thing, buy this! The UDR fits that MO perfectly. I'm having a blast with this thing and I've yet to touch dirt.

    I agree...go with an open diff and maybe a 3 cell battery.....mine rolls over less with the open diff.

    Its all about suspension set up in the front. Read up on camber set up. Then spring rates if you make it a touch softer in the rear it will slide better

    I did that drift like twice. It left black marks as well. Plus I noticed the inside edge of the rear tires, wore a big lip were it didnt wear at all. So it made a mess of them quick.

    Yeah. Kinda' wish the truck had more adjustment up front, especially camber. Can't find any aftermarket parts to allow it and I'm not good enough to mock something up.

    50K rear for me. Minimizes traction roll on pavement, but may be too light for dirt.

    Why not put on harder low traction tires?

    You can put standard 17mm hex wheels on these vehicles right? I don't have one, I have a Slash 1/16 but from my research the UDR has fancy hexes that can take fancy wheels or regular hex wheels

    I got mine for a class project, I am not new to RC by any means, but my first test run of the truck (which was on 6s) I rolled it multiple times from a tad too much throttle under hard steering. It doesn't take much to tip it over with that suspension.
