Well first let me say the dragon lady is an awsome flying model I truely love it. As for alignment I use the good o'l fashioned tape measure and squared the wing tips to the CL of the fuse. I used nylon bolts 1/4-20 with blind nuts and haven't had any problems. I did however offset the engine as perscribed by the manuel because if you check you'll find the firewall is offset. Here are a couple items I did change because of my own concerns. Wing joint, I cut back the covering and glassed the center joint just in case. I also replaced the landing gear mount with 1/4-20 plastic bolts. Steel can rip out the bottom of the fuse if you have a rough landing well it did mine anyway. Ooops. I also pinned my hinges. The cowling needs reinforced at the mounting points or the holes will wallow out. I put a saito 150 in mine and wow what a blast. I inverted it and only needed to cut a hole in th e bottom of the cowl. And the one last thing, the tail wheel I used a Sullivan. Hope I wasn't too long winded.
