Pictured below is a giant-scale SU-26 as sold by Nitro Planes until a few years ago, when it was discontinued. Wingspan is 101", and it's designed for an 85-100cc engine. I may or may not end up with this plane, but am thinking hard about trying to make this happen. It would be another project on the shelf for a while, but it's a lot of plane for $300, and I may be able to horse-trade that cost down a bit. I guess a trailer to haul planes is in my future...
