I don't believe Sig's Astro Hog ever had a wing held on with rubberbands. I have had 3 Sig Astro Hog's with doped finishes.Nothing flies like a Hog. They are alot of fun. I built the last one with half of the diehedial and a larger rudder. It will hold continuous knifedge powered with a YS91. FUN airplane. Enjoy!!
