With a warbird there is a lot more stuff going on. Most of them are fully sheeted, have scale hinges, and other details that are a bit more trickey to build, and will take a lot more time. I have assembled many arfs and built a few kits to this point. I built my first kit two years ago and it was none other than the Sig Something Extra. The instruction book was put together very well and does not leave you guessing about what to do. Many warbird manufactures write their instruction books assuming that an experienced builder is reading them and they can tend to leave out the small things that help out someone who has never been through the process. That being said, if you have plenty of time, patients and are up for a challange go for the warbird! If you have any questions along the way come here. Thats what RCU is for! Above all it is about doing something you love and having fun.
