> Have I done my maths correctly?? I don't know about your math, but my KR will do 193 mph TAS at 1700' turning about 3630 rpm with a Sensenich 54x58 prop. KRs are famous for "breaking the curve" on what passes for prop efficiency. I've done 191 mph with a Sensenich 54x54 turning 4000 rpm, but that prop didn't have enough pitch for this 3100cc engine. Mark Jones is now flying that prop, presumably on the hunt for more deer.
For the newcomers on the list, there's a lot more regarding KRs, speeds, engines, and prop relationships on the "KR info" page at http://www.krnet.org/kr-info.html . Maybe this is a good time to ask for more info so I can update the list, so send your newly updated info to me, folks...
