I think one person also asked if this would be a good second plane with a 46 in it. I believe the plan was to move this engine from a trainer to a 3D plane? A Saito 100, while fun for an experienced pilot would be a waste in this airframe for a second plane in that it likely wouldn't last very long. To answer the the question. No, this would not be a good second plane with the 46 in it, or any other engine for that matter. I would sugest a low wing sport plane such as a Kaos or sportster type thing for your 46. Still lots of fun but much better suited for a second plane.
