Is that on tarmac, or dirt?
60-70mph on pavement is not hard in a 1/8 e buggy on 6s. Same speed on dirt / thin grass takes Overkill level of power, probably on a 1/8 truggy so you have lots of suspension...
A few RTR ideas / examples,
70mph+ on tarmac, running less than one minute, then letting the car cool off - Arrma Typhon 1/8, Talion 1/8 or Infraction 1/7
60mph on tarmac - Arrma Typhon 1/8, Talion 1/8 or Infraction 1/7
50mph on dirt/grass - Kraton 1/8 /Typhon (on 6s) (most any 1/8 truggy on 6s)
40mph on dirt/grass - Slash 1/10 / 1/10 Senton (many SCT on 3s) (most any 1/8 buggy on 4s)
30mph on dirt/grass - 1/10MT like Granite, Hoss
<20mph - any brushed model
The dirt speeds are not the speed listed in 6" tall letter on the box (those speeds are mostly unrealistic except on pavement, single pass), but rather what you can really expect the truck to do out of the box or with minor tuning (pinion swap) without overheating the motor every battery. Also, lots of other cars could be put on that list (they could, this is just examples of a truck class), and some will argue the cars I did put on the list should move up or down a spot or two. But, this is my list.
And yes, the list is Arrma heavy, because i have a lot of Arrma trucks, and know the line well. Lots of other brands can go fast too.
Smaller than 1/10 scale can be fast for cheap, but they often don't have the weight / ground clearance / suspension travel to go fast on anything but pavement.
With that said, a 1/14 truck with a 25mph top speed can feel very fast and fun in a smaller running area, where a 60mph 1/8 truggy would be very boring, because you would not have the room to get it up to speed or use most of it's massive power. Make sure you get the right size RC for your preferred running area.
1/8 - BIG parks, wide open spaces, no people (50mph 10lb truck can break bones of that kid you didn't see)
1/10 - bigger yards, medium size parks, front yard & street (depending on traffic)
1/12 and smaller - small parks, back yards, small dirt lots, big basement / living rooms/garages
YMMV
