Hello All! Thanks to all for the kind words of support & encouragement!
For those desiring correct information about actual performance achieved with the KR 1 or 2, that person truly needs to study the web pages of the people actually flying those KR's. There are KR's reporting best economy cruise numbers of 110mph, but are heavy and "dirty" aircraft lacking wheel pants, and other drag reducing additions or attention to detail. Just to name a few, there are several things that must be considered when analyzing performance of a particular aircraft. The engine seems to get all the attention, but that is just the beginning. How clean is the aircraft, what prop is being used both length and pitch numbers. Look at the difference between Troy Petteway's & Larry Flesner's aircraft. Both using the O-200, but different weights and different props. Larry has more "wetted" area than Troy's, and is using the RAF48 wing, Troy the AS40XX wing. Like we found in drag racing, it is not just how big the motor is, but how well the combination works together. Lots of HP that cannot be converted to thrust is useless. Typically from my study, more horsepower does more to help climb numbers, while cleaner designs and attention to drag reduction does more to help cruise speed numbers. As airspeed goes up so does the drag, so to fly faster, you need to think about more thrust, AND reducing drag or your improvements will probably be very modest compared to what you think. And to borrow a phrase from Larry, "your results may vary".... Colin & Bev Rainey KR2(td) N96TA Sanford, FL [email protected] http://kr-builder.org/Colin/index.html
