Very exciting Keith, once again you are a inovating in the market with found items. Your 44 and 50 are great engines that I have experience with. The 90 seems like such a novel idea and I am anxious to find a reason to get one. The pattern plane from Mr. Blose would be top on my list. How does this engine react to a pipe? Not just for more power but transition and sound? Keep up the good work!
