You have gotten tons of good advice here. I would like to add something. Do you know someone who is a very good builder? Most guys who like to build would love to help someone learn to build. I am one of those kinda guys. I love to build and help other people whenever I can. Maybe the fellow you get in touch with can help you. Aske the guy in your hobby shop if he will help! I would say with the proper help a Hog Bipe should be within the realms of possibility. I agree that the Sig Liberty would be real rough for a first build.
