I got the horizontal stab framed out last night, it took about an hour. With all the major assemblies finished now I can say that it wasn't much more trouble than your average sport plane. Of course that is just the frame up. Now the sheeting and shaping begins. And of course the next few months of my life spent sanding. I do expect things to slow down here. This is a side project and I need to get moving on my 1/3 Sopwith that I would like to fly this summer, and I do have a few other planes that need details here and there. I am a bit worried I might have to go to 2 strokes due to the dimensions of the nacels and what has to fit behind the firewalls making it difficult to recess them. I still have to do some carefulmeasurements. If I do have to go 2 strokes I am thinking about possible options. But without question it will be gas and a conversion gas. Glow is not an option.
