Info-Central had two nice thrust-to-weight ration charts that were perfect for quick reference, especially at RSO tables. Since Info-Central is gone, would someone have saved a copy of these two charts that they could share?

There are two here on page 6, although the quality is kind of grainy

use the wayback machine.. https://web.archive.org/web/20120902192900/https://www.info-central.org/?article=121
Thanks guys, exactly what I was looking for. A shame that Info Central is all but lost. The last of Darrel Mobley's legacy is officially just a wayback machine link now.
Quick shortcut (that follows the 5:1 rule) when assembling your rocket and you do not have a chart:
(Wt in lbs.) X 22.5 = min avg thrust required.
That follows the green line on the chart for large rockets.
(Wt in lbs.) X 22.5 = min avg thrust required.
That follows the green line on the chart for large rockets.
Thanks Dave, it is good to have both for reference.

Resurrecting this old thread.
Does anyone have these thrust to weight safety charts in Excel format? The ones I see are JPG and they do not print to large sizes cleanly.
Thanks

I have one where you can input the weight and motor and it gives the ratio.

Thanks Ben. I'm looking for something I can print and have on the RSO table.
