You can't get plans for these two specific planes because they are available as kits. If you're looking to build a similar plane to either one then I would suggest that you go to the [link=http://www.rccombat.com]RCCA[/link] web site and review their forum. You can also go to the [link=http://www.texascombat.com]TexasCombat[/link] web site and review their workshop section and forum for more information concerning the Cobra which is the flying wing that you referred to.
