Prior experience with LEGO Digital Designer led me to expect significant trouble with trying to build the speeder digitally. In fact there were very few problems — some pieces (notably the fins) unavailable in the right colors, and some (notably the stud shooters) unavailable at all. So I made a few substitutions. I left off the tools hanging off the side and the stuff stowed inside, and the minifigs of course. I mounted the whole thing on a stand to elevate it. Ta daa. Now I can work on digital mods.
