You wrote: 1) "Is yours a P-TIP too OC ?" Yes. My 68 inch diameter by 69 inch pitch Prince prop was purchased in 2001 for a total cost of $1509 US. It is referred to in the correspondence of that time as a "composite" P-Tip and I can see a faint fiber weave pattern showing through the gray paint so I assume that is fiberglass covering the laminated wood core. The carbon fiber props described in the present day Prince web site are finished with a clear coating over the carbon fiber unless paint is specifically requested. 2) "When I bought mine, Prince claimed that a P-Tip versjon would "act" like a normal version with 4inch or so larger diameter and same pitch." Here is Prince's web site for quick access: http://www.princeaircraft.com/ And here are his current claims for P-Tip and scimitar blade shape performance: http://www.princeaircraft.com/TheProp.aspx OC PS: I flew a rented TCM IO-240 B3B powered Diamond Katana DA 20-C1 airplane for a few years while I was building my KIS TR-1. It had a gray painted Sensenich prop and it took me several attempts to determine that it was indeed a painted wood prop rather than a painted metal prop. ========================================================= From: "Hans Christian Erstad" Sent: Saturday, February 26, 2011 2:38 AM Subject: SV: KIS-List: Re: KIS landings Hello OC As I reported earler I usually get 2200 RPM static and 2800 WOT (and maybe exceeding 2800 after a minute or so, but I never run wide open and 2800 for longer times) at 2-3000' altitude This is with IO-240A and Prince P-TIP with 62 dia and 68 pich. (manufactured around 1997-1998) Is yours a P-TIP too OC ? When I bought mine, Prince claimed that a P-Tip versjon would "act" like a normal version with 4inch or so larger diameter and same pitch. (I cannot remember exatly what he said) So the only reason to have a P-Tip would be to increase ground clerance and decrease tip speed. Less tip speed could in theory result in less noise (one of the reasons I went for Prince and P-Tip). In case someone is not familiar with the Prince term "P-Tip", it is sort of a winglet, and I am sure Prince web site explain it all. (but have not checked) Regads Hans Christian, TR-1 #032 ________________________________ Message 2 _____________________________________ Time: 02:24:59 PM PST US From: Subject: KIS-List: KIS TR-1 Propeller 2/26/2011 Hello Alfred, You wrote: "........ I'll be using airfields at 6000 ft AMSL at temperature of 35 to 40 degrees C." That helps me understand your desire / need for more takeoff / climb RPM / power out of your engine - prop combination than I am faced with. The Prince propeller selection Wizard is a bit puzzling because it has two different propeller recommendations for what appears to be the same airplane and engine combination. A) If you follow the input trail of "KIS TR 1 IO - 240 - 125HP" you wind up with a 68 X 69 propeller recommendation. (Which is what I have.) B) If you follow the input trail of "KISS - IO 240 - 125 HP" you wind up with a 62 X 68 propeller recommendation. See here: http://www.princeaircraft.com/PriceOrder.aspx One would think that the 62 X 68 prop would be more of a takeoff / climb prop than the 68 X 69 version. Maybe a conversation with Lonnie Prince is in order to sort out and refine / clarify the recommendation. 'OC' Baker Says: "The best investment we can make is the time and effort to gather and understand knowledge." PS: What part of the world will you be operating in with those field / density altitudes and temperatures? ============================================= From: "Alfred Prosser" Sent: Saturday, February 26, 2011 9:09 AM Subject: RE: KIS landings Thanks for the info on your propeller performance OC. Thing is, I have to rig my plane for operating at density altitudes of 10,000+ feet because I'll be using airfields at 6000 ft AMSL at temperature of 35 to 40 degrees C. That's a different kettle of fish altogether. Hence the need for every ounce of power I can get out of the engine at take-off.
