The range given by Don Reid of 1200 to 4000 hours may sound somewhat alarming, but it goes with building this or any type of large project. There are probably three types of people who build the KR. The first type is a person who has a genuine interest in aviation and wants to build a plane because he thinks it would be fun and a worthwhile project... and in the end he has something he can fly. This builder will likely build his plane in 1500 hours or so, perhaps a little more if he goes down the road of experimenting with new design issues. The next type is the one who is interested in having his own aircraft, but either can not afford to buy a spam can, or the thought of it repulses him for other reasons. This individual's goal is to have an aircraft that will fly and as such will be the one who will build his project in a shoter time, 1200-1500 hours. The final type builder is one who is building either a work of art or is trying to design something truly unique. For this builder, time is not an issue as having a flying airplane is not as important as all the design and effort that goes into making this a plane like no other. 2000+ hours for this builder is nothing and he does not consider a high number of hours to build a negative factor because it is not his focus. This plane may never even fly because flying it is not the prime motivator. You will find very few people who fit exactly into any of the categories above, as we all probably have some of each in us. I personally want an airplane that I can fly, and am aiming at 1200 hours to do it in. I think this is a totally reasonable amount of time. I am very thankful to the people who are into the design aspects, as they are making my life easier when I do make minor changes to the basic design. I hope this clarifies the issue of building time for you... it is all a matter of what you want to do.

I have to agree very much. Needless to say, I am in the third group. For some builders, money is no object. In my case, it is more like time is no object.

Well of course there's X-Plane (http://www.x-plane.com), which is probably the best general technical simulator.
