For sale is a very nice kit built Aeromaster Biplane. It is being sold as an airframe with standard Futaba servos. It has a OS 61 FX which is included but was used for fit and may not run although it has great compression and turns over smoothly, I don't know as I have not run it. When I bought it that's what I was told that it had in it for power with a pitts muffler. I had one laying around and it fits perfect so I'm leaving it in as I will not be using it. It does not include a muffler. The plane is near perfect and someone did an awesome job on her. The cowl has a few small cracks on it as seen in the pictures. It has a 48 inch wingspan and I do not know what kit it is.
