Updated November 2011, This month I changed my propeller from a Sterba 54x50 to a 54x54. The result was positive.
While I did not have an improvement in overall top speed, the overall RPM band came down and I can now cruise
comfortably at 3000 rpm and get 130 mph - a 10 mph improvement. Since my 1st flight conducted on 2 Sep 06, I've
managed to fly 385+ hours to include trips to the KR Gatherings and Oshkosh.
The KR-2S is a experimental airplane, a home built. It is a single engine low wing design airplane. My airplane has a
normal cruise capability of 130 mph with 140 mph maximum speed in level flight with two passengers. I purchased the plans
for the KR2-S from Rand Robinson in 1997. I studied the plans for a year before I began construction in June 1998. My
plan was to finalize all design decisions before I began building the airplane. I pretty much stuck to the plans with only a few
modifications. I widened the fuselage 1.5" and installed the trigear since I have little tail-dragger experience. I am using the
standard RAF 48 airfoil. Engine is a aero converted VW engine, a Revmaster 2100. The airplane was scratch built as much
as I thought was practical to save on costs, but at an increase in building time. It took 1500 hours and 8 years to complete
the project. Total cost was less than $15,000.
