If you're looking for that kind of speed, hp, and range, the KR is not the airplane for you. There was a 180 KR, if you want to call it a KR, at one of our Gatherings but I don't think it had the performance you are looking for. I'd suggest you stick to the RV series. By the time you made all the necessary engineering changes to get the airplane you're looking for you will have as much invested as in the RV series. Even at that point, your RV will have three times the resale value. The KR type of construction may be the cheapest but not necessarily the least expensive when you consider the total picture.
