This technique shows a simple way t' make correctly sized decals for downscaled/upscaled rockets. T' first step is t' obtain a scan o' t' original rocket's decals. Once they are obtained, open it in a picture editor. A common editor like Paint will work fine. In this case, me hearties, t' decal will be resized t' fit a BT-5 downscale o' t' Estes M-104 Patriot. Ahoy! Now t' scale factor must be obtained. A simple way t' find out what it is: take t' diameter o' t' downscaled/upscaled rocket and divide it by t' diameter o' t' original rocket. Begad! Convert it into a percent. Aye aye! In Paint, go t' Image and then Resize/Skew.

In t' resizin' section, me hearties, enter t' percent obtained earlier (make sure t' percent is rounded t' t' nearest integer – Paint will nay accept decimals) in both Horizontal and Vertical.

Now, click OK. Begad! T' resizin' is now successful and now can be printed and applied t' rocket.
