It's availible on www.richmondrc.com... The site is kind of hard to navigate but if you look in the upper left hand corner you'll see the VMar Online Store text that you click on...As far as your engine choice goes that's perfect. I have a 52 magnum on mine with a 12x4 prop and the verticle is insane... It very light weight and fragile, especially the wings... Other than that it flies pretty well but the KE isn't that great... I had to cut out some of the rudder to get enough throw for hovering... For the money, I really can't complain though.
