I was just curious, FT Bloody Baron of which I downloaded from this website, how do you guys blow up the plans to the correct dimensions. 73.7 cm wing span to wing span? I saw how you guys did it on paper, then trace it and cut it. Now how do you blow it up to the correct dimensions? I’m going to put wheels on it at the center of gravity and a trailing end. Pre-cut is what like $10-$15 dollars.
