I think some of you are missing my point... Almost any LNC-2 will go to 200 knots...
It's getting past the 200 knot mark is not quite as easy. This takes the extra touches like more HP, light weight, straight build, reduced drag, etc.
There are about a dozen LNC-2's here and most of them get to 200 knots (not all) and a few get well past that. Those few have allot more time into them to get them faster. The 200 knot wall is not the end of the LNC-2 speed it's just the easiest to reach. That is the power to drag limit on this design.
Increase the power, reduce the drag and the limit is raised but it is in no way linear past 200 knots . It is very exponential.

Oscar Grassle's 160HP 235/320 would go 240mph/208.5k at 3150rpm at 5500' dalt with my two-blade design; that's what you would expect with a 187HP engine at 2700rpm. It would also go 233mph/202.4k at 3090rpm at 10,000' dalt, or the equivalent of 183HP engine at 2700rpm! These numbers were verified with a GPS on two-way runs. At 1000' dalt, it would go 242mph/210.3k at 3200rpm, the same as a 189.6HP engine at 2700rpm.
