I built the Astro Hog when it first came out. Flew great. The Sig P-51B is one of the best flying R/C aircraft I have ever owned. I'm guessing I have owned about 100. I wanted one all along when I saw them in the old RC Modeler and read how much everyone just loved the way they flew. I still have one in the Shangrila version with mechanical retacts and an Evolution 100. Just flys great and really slows down on landing with the big flaps. People just can't believe how stable it is in slow flight. I am looking for another one to do in electric. Let me know if someone has one NIB please. Even though I did not know them, Hazel Sig and Maxi Hester were HUGE in the success of Sig. Many in the old modeling community where everyone knew everyone said they were just great people!!!!! I called Sig just before they changed owners and asked bout ordering the P-51B ARF. The lady at Sig said they did not have any in stock and would probably not order any more because the Chinese manufacure of their kit was asking for more $$$. Get this for service, she gave me the PH # of 3 or 4 of their small hobby shops that she thought might have one still in stock. Bingo, scored my favorite ACFT! It was as couple of years back and the price was about $329.00. Bad news was the shipping was as I remember over a hun!!!! PS, the lady at Sig told me they would have to order kits and such by the thousands to get a reasonable pirce on them. Absolutly no small orders possible. Wallace Tharp
