But out of curiousity, let's take for example, my next major project, a 1/6 scale Albatros CI with a 85" (top) wingspan. What would be the list of electric components and prices I would need for something like this. At this moment we're planning to use an RCV 91CD. Since the CI has a pointy nose the only way to deal with this is to mount the engine sideways so that we have at least one clean side view (the left side) and can use a full dummy of the Mercedes engine. But I suppose electric (probably with a shaft extension) is worth considering.

But really what would it take and what would it cost. First or all what would be the equivalent in terms of Engine size?
