Installing the engine upright is going to require a fair amount work. Looking at the manual, the nose is very narrow as an original glass fuse was used for the mold. So a large case engine may have the same issues. Also the tank would probably be too high, again look at he pics in the manual. I dont think there's much room to move down as it looks like there's a floor molded in for the retract bay. Another issue would be the throttle servo's location as it would have to be moved. Lots of questions that can't be answered until we get one in hand.
