sorry seem to have posted question in the wrong section
lets say a pro 4 has a roll out of 42.38 and is going very well on a certain track
will a losi with a roll out of 42.33 ratio be the same
or close
or far off the pace
thanks guys

That numerical difference in that rollout should be insignificant on the track.

Let’s assume the two cars are using an identical battery, motor and ESC.

If that’s the case, then in theory, they should be very, very close in straightaway speed.

However, that’s not always the case relative to an overall lap time.

Assuming the aforementioned identical electrics, what you’re actually measuring by comparing speed of those two cars is:
Rotating Mass
Overall car weight
Drivetrain drag
Aero drag
Corner speed – the faster a car is leading onto the straight, the faster it will be down the straight…
Rolling resistance
Etc, etc….

In other words, the Pro4 could be faster because of any one of those things or vise-versa in favor of the Losi. So, you arrive at the classic RCTech answer, “it depends”…
