Hi, i am newbie and have'nt built for many years. I have seen a plan for an Avro Vulcan Slope Soarer in RCME Plans Service, the description does'nt give a lot, but does mention it is a Powered Slope Soarer. The model number is RC1528. I wanted to make this kit without power, has anyone made this kit? Do you think this model will fly adequately on a slope without power? Many thanks, Bob
