"How to figure out top speed"

"came up with a little speed formula here so that you guys can get the true speeds of your Xmods using only a tape measure and a stopwatch.

Here is the formula and explanation:

5280ft=1mi
An Xmod is 1/24th scale
Therefore an Xmod scale mile is 220ft

Use a tape measure and make 2 marks in the street/parking lot, one being at 0ft and the other at 22ft.

We're working off of 1/10th of a scale mile (22ft).

now measure the time (with the stopwatch) it takes (at top speed) to go from 0ft to 22ft (take a good running start)

Let's say it took 5 seconds

5 seconds divided by 22ft=4.4 feet per second

Divide that by one mile 5280ft

you get 1200 seconds

divide that by 60 to get MPH (in this case 20)

Hope it's not too complex but if you don't have a radar gun then this will solve all the bickering over how fast the thing is going and people guessing it's going 20mph when it's doing 17.

btw...if you're smart enough to figure out the formula then you can use it on any scale vehicle."

Hope this helps!

You dont need to use a scale quarter mile. You can just use any distance over about 20ft so you can get an accurate reading.
