Kenny:: I have taken over a KR2 project and am kind of "Rolling the Dice" on this one. The craft must meet of couse meet all of the requirements of the "Sport Plane" catagory. The most difficult to achieve of these to meet is the construction of the craft so that its top speed "clean" in level flight doue not exceed 138 mph(120 kts) nor does the stall speed "Clean" exceed 51mph(44 kts). I think this will be impossible to do with an engine larger than the 1915 cc Great Plains engine or maybe even their 1835 cc engine. I also think that will almost be mandantory to build it as a tri-gear in an effort to get the speed down. From the stand point of stall speed you will almost need the longer wingspan of the KR2s and even with that I found that wing area would limit your gross weight to 887# acording to the "AirCalc" program.(Downloadable from the net). The standdard KR2 wing will force your max. allowable gross weight down into the mid 700# range to get to the 51mph(44 kts) stall speed which effectively makes it a single seat craft. I spent about 4 to 5 months exploring this and it is a close call and be advised that the KR2 as a sport plane is not on the approved FAA list so it will attract a lot of scrutiny for sure. This most likely because it was originally designed as a fast retractable craft and most are built with engines to powerful to keep the speed down as the design predates the LSA catagory by 30+ years.
What ever you do join your local EAA chapter and work with the chapters EAA Advisor/Counsulor. Good Luck and get in touch with your local EAA before you start. The importent thing that the FAA cares about is that you meat the requirements of the LSA catagory.
