I purchased a completed tri-gear KR-2 with a Continental A65. The plane had not flown and was out of annual. I am currently refurbishing and preparing for the condition inspection. Equivalent flat plate seems to range from 1.18 to 2.22 based on data from various flight reports and KR-2 specs. (Who knows what it really is?) Based on that, the A65 provides enough power to cruise in a range of 144 to 177 mph at 4.4 gph or 128 to 157 at 3.2 gph. The high end speeds correspond to the official KR-2 specs with a gross weight of 900 lbs, but all flight reports that I have found indicate less. The average of the data I have accumulated (not including KR-2 spec data) would indicate a max speed of 164 mph, cruise @4.4 gph of 153 and economy cruise @3.2 gph of 136. In a little turbulence, with the KR-2's wing loading, the economy cruise speed will probably bounce you around quite a bit.
Your results certainly will be improved by keeping your project light, as well as taking care with your finish and engine cooling drag. Hopefully, someone else will have some actual data and will be able to answer your question on g loading also.

I am purchasing a krt project, and my question is i have a continental A65, how do they do in the kr2 what are teh typical cruise speeds with this engine, and will using carbonfiber or kevlar on the wing layups save much weight. what are the g limits to the design?
