Good Day

I'm itching to buy another car. I have a 1/16th slash that is fun to race and is sort of my work car, I have found that it wants to roll extremly easy, is the mustang the same way? its a very similar design so I'm assuming it is, but all the youtube videos show it as being more stable.
how slow is the brushed mustang?

I'm torn between the mustang and the Summit. I like the size because its easy to keep in the cab of my truck for those days that feel long
