Connect? par Motorola robert gill via KRnet <krnet at list.krnet.org> a ?crit?: HI, i'm after some info about installing a Rotax 912 ULS 100 hp in my kr2. I am replacing the Revmaster R2300, I am sick of spending more hours fixing the engine than flying it. about 150 hrs flight time and 300 hours repair time.what I need to know is, has any one out there have a 912 ULS in there KR2, what my concern is with the reduction drive at 2.43 equating to 2380 RPM at the prop would a 58" diameter prop be enough for take off, then in min cruise power with 2057 RPM at the prop is it still going to work, currently with the R2300 'when its going' I am getting 135 KT cruise at 3000 RPM.what I am guessing is with a 58" prop (max dia I can safely go) it would have to have a hell of a lot of pitch on it to get the engine loaded right, then with that much pitch am i going to have more trouble with the prop stalling say when trying to take off? prop manufacturer here in Oz. said that that engine and there prop would give me an estimated cruise about 150-160 kt cruise WOW!! if it works. I know its not the correct way to look at this but 2000 RPM at the moment i'm barely keeping the plane flying?If anyone has installed a 912 with a 58" prop what prop are they using, and how much success are they having with it.Another engine option I am considering is the new D-MOTOR LF26 specs look really good to suit a KR2, direct drive, 92 Hp @ 3000 RPM, water cooled, EFI, 88 Hp @ 2800 RPM for cruise,8 liter/hour 2.1 gal/hour for the yanks, (that near the doubles my fuel endurance), 67 kg ready to fly weight and its tiny and apparently very quite. and has down loadable diagnostics which can be sent to the manufacturer for analysis or tuning, and cheaper than a 912 'not by much'. _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
