I built his single engine Comanche years ago. It was a good kit, with, what I thought were, good plans. Sorry for the lack of pictures, but it was many years ago. I put in it the largest engine available to me at the time, a OS MAX .50 with no muffler, just a back pressure plate. That might date me and this build. It was marginally powered I thought. Today, it would be much different. I would say, go for it. His kits fly well and have good lines. I have considered building the twin myself.
