As Larry says, if you want a KR-100, just narrow up a 2S and use the new airfoil and tail plans. ?You'll have a much better plane. ?I wouldn't put a great deal of stock in the 262 mph speed listed for the KR-100. ?The formula racers using an O-200 were typically turning those engines just a bit over 4000 rpm. ?It's likely that speed was reached running the engine that way, so I wouldn't count on that kind of speed with any engines normally found on a KR. ?But you can build yourself a plane that will push 200 mph pretty easily. -Jeff Scott Los Alamos, NM
