Does anyone know if its possible to create a Fly!II twin engine aircraft where the engines are in-line? For example, the push-pull cessnas? I've seen one I'd love to work on, but don't know if it's possible.

Sure, I don't think this is a problem at all. Just create however many engine objects as you need in the .ENG file, place their thrust positions using the tags. The ability to have any combination of engine types placed wherever you want them has has always been available in the Fly! architecture.Chris WallaceOttawa, Canada
