It works swell and is much fun to fly the KR2S on MS-FS. It sure does float on landing; I haven't found the flaps lever! Usually floats to the far end of the runway.... And when you release the brakes, it will taxi at full idle at 54 MPH.

It shows the pitot tube with small vertical & horizontal vanes to keep the tube from bending. The tube is about 6 feet long in front of fuselage. The web site you indicated is very interesting.

That is very close to what Marty Roberts was running on his 0-200 and he thought mine might be a bit low in pitch. That would be o.k. with me as my KR will be heavy and that will let the engine turn up a few more h.p. and should help my take off and climb performance. IMHO,go for the largest diameter you can, considering prop speed and ground clearance, and adjust the pitch accordingly. Marty has run several props on his 0-200 over the years but he's not on the net. Maybe Jean Veron could help out here or if Leo from Brazil is still on the net, he was going to be running a 60X66 on his 0-200 powered KR. How is that working out, Leo? These numbers should work out close if you can get 110h.p. out of the Corvair. I'm guessing your RPM will be within 10 % of the 0-200. I'm only going by what I've seen in the past and I'm sure there is probably something "scientific" about how props work if someone wants to go into all that stuff. :) Larry Flesner ------------------------------ Date: Fri, 22 Mar 2002 13:05:16 -0500 To: zipperts@whidbey.net ("Dave and Tina Goodman"), corvaircraft@usm.edu, krnet@mailinglists.org From: FLYKRS@netscape.net (Mr. Bryce Guenther) Subject: RE: KR> Prop size for 2700 Corvair motor Message-ID: <6BBCDE04.2059899E.000444BF@netscape.net> Greetings Dave I've got an 0-235C1 on my single KR2 with a wood 58 x 72 prop. For static I'm pulling 2250 RPM. On your Corvair and a matter of fact on all aircraft installations the thought of LIMP mode RPM is unfortunately overlooked. People select all out performance ideals for propeller design selection but don't consider this senario "What If". What if one cylinder is inoperative "fouled plug" Sticky valve" "Ignition problem" All these will drop the RPM to some degree. Will the aircraft be able to continue to fly to safety ? The Climb Propeller will have higher rpm than a Cruise Prop with one dead cylinder is the thought. The Aircraft Manufaturers are not ignorant of this single failure mode after all because it is a basic safety design principle. We KR pilot might consider this when we choose a propeller. "Dave and Tina Goodman" wrote: >Gents, > >Okay, maybe I am missing some traffic from being gone for a good part of last year. Is there a consensus on what size prop to use with the stock Corvair motor on a KR-2S platform? I am looking to order a prop here in the next few days, and looking through my archives I could not really find anything on this. Is 56x62 to mild? How about a 56x71? My objective is to have a cruise in the 170-180 MPH range, with a top of 200. I have looked at the charts, and factoring in the 10% slip Tony Bingelis notes, it seems to me I would end up with a giant pitch in the prop... and it just seems too big to me. Do I need to be thinking about a 54-inch prop, higher RPM and a medium pitch? > >My setup will be a 2-blade prop without starter (hand prop), most likely a Prince P-Tip. > >I am at a loss, so any inputs would be of tremendous help. > >The unfrozen-caveman-airplane-builder seeking guidance in a modern world! > >Respectfully, >Dave "Zipper" Goodman > -- Flying is Fun and a Thrill that nearly nothing else can compare. __________________________________________________________________ Your favorite stores, helpful shopping tools and great gift ideas.

He installed a standard metal prop for the 150 Lyc., I don't know what pitch, and got a better rate of climb and about 5 to 7 mph better cruise. He may have had a prop to engine mis-match or something but I'd sure check it out before spending that kind of money.
