Hi guys, been off the list for a while. I have finally taken delivery of the 3100 motor that I bought from John Monday (Thanks John) and was reading through an old issue of Contact! that John included in the crate(thanks again John). There is an article on Paul lipps and his "ELIPPSE" propellor which made for very interesting reading. Would it not be possible to get him to design a custom prop for the vair powered KR's just like the new airfoils were made for the KR. There could be a design for the 2700 guys and one for the 3100 guys which should be pretty close to being identical. It might look weird but the numbers on his own Lancair speak for themselves. Look what it did for the biplane Reno racer! A KR could be chosen as the "average "drag model and the numbers calculated from that. I know the props made by Catto Props (the guy that carved the prop for Paul)are fairly pricey but what about those of us not intimidated by the task of carving one ourselves? There might be a weight problem but I don't think that should concern the guys switching to the fifth bearing, and it shouldn't make any difference with my soft drive setup either. Just a thought, it sure would look good to have one of those perched on the front of my KR!
