Steve Glover is probably the guy to answer the KR100 question, but best I can tell only one has ever flown, and it's now stripped to a shell somewhere. Plans were never sold for it, which I view as a missed opportunity to further the breed. As for the 84 HP Corvair, conventional wisdom is that the 84 HP engine weighs the same as a 95 or 110 HP engine, so you'd be wise to use the larger long-stroke engine instead, and the 95 HP and 110 HP (and their parts) are likely more plentiful anyway. The 84 HP engine is the earlier short-stroke engine, so it's handicapped from the start. If you already have an 84 HP Corvair, you could sell it or parts of it on ebay and buy a 95 or a110 to replace it, but there are enough parts that interchange that you could use it as a parts donor for the larger engine. Don't extrapolate this theory to the 140 HP engine though...they are more likely to drop a seat than a 95 hp or 110. After you swap the cam in the engine to one better suited for aircraft use, you'll have about the same power out of a 95 as a 110, so don't let that be a factor in the decision either. For more on Corvairs for aircraft purposes, you need to buy William Wynne's Conversion Manual, at http://flycorvair.com/products.html , especially before you spend any money on the core engine. The bus engine is the same story....it's too easy to increase the displacement with larger cylinders to use the stockers and limit the power. Great Plains Aircraft is the place to look further into that. See http://greatplainsas.com/index.html .
