Lonnie B's Conversion Chart

Lonnie Buchanon made a conversion chart for upscales and downscales using Estes body tubes.

"If you build upscales and downscales of Estes kits, you may be interested in a chart I have posted here that helps you quickly find the multiplier to convert measurements from one Estes body tube size to another. In other words, if you want to make a downscale Red Max from BT-55, you choose BT-60 in the left column and then go across the row to BT-55 to find your multiplier (in this case, .8094), then multiply all the measurements by that number. If you're printing decals or a fin tracing, change the multiplier to a percentage (in this case, 80.94%) in the Print window."

Thanks Lonnie!
